Also switch to using tags instead of raw commit hashes. Makes testing
easier and also removes the risk of Github deleting commits due to

* Remove global fDIP0003ActiveAtTip and fix wrong use of VersionBitsState in auto IX (#2380)

* Remove global fDIP0003ActiveAtTip flag and always use VersionBitsState

fDIP0003ActiveAtTip was used much more often when introduced but turned out
to be not very useful in most places. Always use VersionBitsState now.

* Fix wrong use of VersionBitsState auto IX

* Make sure isAutoLockBip9Active flag is reset in case of chain reorgs

* Fix prepare_masternodes/create_masternodes in DashTestFramework (#2382)

Specify masternodeblsprivkey which is required in masternode mode now.
This should fix IS test failures which occur because of `Warning: You should specify a masternodeblsprivkey in the configuration. Please see documentation for help.` init error (there are other issues, so auto-IS test are still going to fail).

* Implement mt_pooled_secure_allocator and use it for BLS secure allocation (#2375)

* Add pooled_secure_allocator and mt_pooled_secure_allocator

* Use mt_pooled_secure_allocator for BLS secure allocation

The old solution relied on thread-local-storage and was thus not compatible
to libc6 2.11 (which is the minimum supported version we use).

Also, the old solution turned out to be erroneous. It would have crashed
or memory leaked when ownership of CBLSPrivateKey would be handled over
to another thread.

* Add new header files to Makefile.am

* Fix copyright headers of new files

* Bail out early from secure deallocation

* Clean up global BLS keys when shutting down

* Rewrite handling of too long depends builds in .travis.yml (#2385)

The old solution was unnecessarily complicated and resulted in failed tests
to be shown as successful (the exit code was ignored).

* Support "fast" mode when calling sync_masternodes (#2383)

This will call "mnsync next" multiple times to force finishing of mnsync.
Also reduce sleep time to 200ms.

* Implement RemoveAskFor to indicate that we're not interested in an item anymore (#2384)

* Implement RemoveAskFor to indicate that we're not interested in an item anymore

When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.

RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).

* Call RemoveAskFor whenever we receive a message

* Only pass hash instead of CInv object to RemoveAskFor

* Don't revert to INV based block announcements when the previous block is the devnet genesis block (#2388)

Assume that the other node already has the previous block if it matches
the devnet genesis block.

* Prepare DIP3 for testnet and reuse DIP3 deployment for autoix deployment (#2389)

* Add BIP9 parameters for DIP3 deployment on testnet

* Remove autoix BIP9 deployment and reuse DIP3 deployment

* Add BIP9CheckMasternodesUpgraded to chain params

This controls if miners should check for upgraded masternodes first before
adding BIP9 bits to the block version. This only makes sense in network
where masternodes are up and running before BIP9 activation, which is not
necessarely the case in regtest and devnet.

Also refactor ComputeBlockVersion to use fCheckMasternodesUpgraded instead
of the inverse fAssumeMasternodeIsUpgraded. It is set to false by default
and only set to true in CreateNewBlock.

* Check for upgraded masternodes for DIP3 activation (only mainnet and testnet)

* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION

We probably have nodes with 70211 already running on testnet.

* Bump version to 0.13.0 (#2386)

* Fix crash when deterministic MN list is empty and keep paying superblocks in this case (#2387)

* Don't crash when spork15 is enabled but no MNs have been registered

* Don't bail out when no masternode payee is found

We should pay superblocks even if no masternode payee is found.

* Add missing newline to LogPrint call

* Handle review comments

* Add merkle tree and coinbase transaction to the `protx diff` rpc command (#2392)

* PrivateSend spending txes should have "outgoing" icon on overview screen (#2396)

* Relay txes through MN network faster than through regular nodes (#2397)

* Half the delay for relaying txes to Masternode outbound peers comparing to regular ones

* No delay for relaying txes if our node is a Masternode

* Force fvisibility=hidden when compiling on macos (#2398)

This should remove tons of warnings about mismatching visibility

* Do not ignore patches in depends (#2399)

* Ensure correct order of destruction for BLS secure allocator (#2401)

Uses the same trick as LockedPoolManager::Instance()

* Undefine DOUBLE after include Chia BLS headers (#2400)

These cause compilation errors on some platforms.
Observed this when I tried to cross compile win32
locally on a Debian Stretch machine.

* Properly escape $ in Jenkinsfile.gitian (#2404)

* Sign ProRegTx collaterals with a string message instead of payload hash, split `protx register` into `prepare`/`submit` (#2395)

* RPC: Add help details for the bls RPC (#2403)

* RPC: Add help details for the bls RPC

* RPC: Refactor to match gobject RPC behavior

* RPC: Use command instead of strCommand for consistency within file

* RPC: BLS help cleanup

* RCP: Remove leading underscore on bls_help

* A couple of fixes for init steps (#2405)

* fLiteMode should be set via GetBoolArg before first usage

Also move related stuff to be closer to each other

* Cleanup Dash-specific init steps

* Move deterministicMNManager creation slightly higher for consistensy

* A couple of fixes for shutdown sequence (#2406)

* Do not run scheduled DoMaintenance if shutdown was requested

* Don't dump cache files if the load sequence was interrupted

* Stop privatesend and release keys before wallet flush

* fix typo

* Trivial: Protx operator reward clarification (#2407)

Add decimal places to clarify:
1. Non-integers are valid (e.g. 3.25)
2. Granularity - anything beyond x.xx is rounded (e.g. 3.259 -> 3.26)

This is due to DIP3 allowing values 0-10000 for operator reward (1/10000
= 0.01%)

* Fix p2p-instantsend.py test (#2408)

* Update Chia bls-signature to latest version (#2409)

Brings in:

* Explicitly specify which branch of Wine to install (#2411)

Specifying only `wine` results in this message under Ubuntu Bionic:

Package wine is a virtual package provided by:
  wine-stable 3.0-1ubuntu1
  wine-development 3.6-1
You should explicitly select one to install.

Compilation

* Allow collaterals for non-DIP3 MNs which were created after DIP3/BIP9 activation (#2412)

* Remove reference to now removed "protocolVersion"

* Allow to use non-DIP3 collaterals after DIP3 activation

This removes a rule which only made sense when we assumed all collaterals
would remain in DIP3 ProRegTx transactions after DIP3 activation.

As we allow to refer external collaterals now, this rule should vanish as
well.

* Sleep in case block time is ahead of real time

See comment. This was not a problem before as we had enough time passed
between the last block that caused this and the start-alias call.
Now we added another start-alias call which is directly after we generated
many blocks.

* Fix auto-IS tests (#2414)

* no `-debug` by default (it's too heavy)

* drop useless `sync_masternodes` calls and add a couple where they could be actually usefull

* change autoix-mempool.py test logic:
1. use separate nodes to send test txes
2. sync nodes while filling the mempool

* Add 5th denom, drop deprecated logic and bump min PS version (#2318)

* Bump PS
- add 5th denom (0.001)
- always allow OP_RETURN in PS collaterals
- collateral amount is always 1/10 of the smallest denom
- bump MIN_PRIVATESEND_PEER_PROTO_VERSION to 70211

* drop backward compatibility in dsa/dsq serialization

* Use GetSmallestDenomination() in GetCollateralAmount()

* Allow reusing of external collaterals in DIP3 (#2427)

* Allow to reuse collaterals and addresses in ProRegTx

This also requires to move out the duplication check from CheckService to
the 2 individual ProTx check methods.

* Implement replacement logic for reused collaterals

* Add tests for new replacement logic

* Parallel ASN resolve and allow passing of input file names to makeseeds.py (#2432)

* Also include confirmedHash in DIP4

* Implement CalculateQuorum and CalculateScores in CDeterministicMNList

* Use new ProRegTx based scoring function in GetMasternodeScores

* Update test vectors for simplifiedmns_merkleroots tests

* Restart MNs in DIP3 tests even if collateral has not moved (#2441)

These need to be restarted even in this case as keys are cycled when
upgrade_mn_protx is called. This resulted in invalid IX votes but was not
noticed because only 2 MNs were affected (still 8 of 10 votes succesful)

* Make error messages re payload a bit more specific

* Log mempool payload errors instead of crashing via assert

* no cs_main in specialtxes

* Be more specific about tx version in conditions

We don't want to set rules for version 4+ txes atm.

* More checks for tx type

* Revert #2441 and retry fixing (#2444)

* Revert "Restart MNs in DIP3 tests even if collateral has not moved (#2441)"

This reverts commit 153afb9.

* Reuse old legacy MN key when upgrading to protx

* Remove restriction that forced use of same addresses for payout and collateral

* Allow P2SH for payout scripts

* Move internal collateral check to the else branch of the external collateral check

* Also forbid reusing collateral key for owner/voting keys

We previously only checked for the payee key.

* GetMasternodeInfo with payee argument should do nothing when DIP3 is active

Also change ComputeBlockVersion to directly use mnList.GetMNPayee()

* Do not use keyIDCollateralAddress anymore when spork15 is active

* Fix check for number of params to protx_update_service (#2443)

* Pass "-parallel=3" to reduce load on Travis nodes while testing

* Make sure protx_update_registrar adds enough funds for the fees

FundSpecialTx must take the size of signature into account.

* Test P2SH/multisig payee addresses in DIP3 tests

* Fix test_fail_create_protx in DIP3 tests

This slipped through in a previous pull request and makes tests fail.

* Allow to specify how log to sleep between attempts in wait_until

* Use ForEachMN and GetMN in BuildDiff instead of directly accessing mnMap

* Implement BuildSimplifiedDiff in CDeterministicMNList

And use it instead of BuildDiff in DIP4

* Allow P2SH/multisig addresses for operator rewards

There is no reason left to stick with the P2PKH limitation

* Sleep longer between attempts in sync_blocks

* Remove few leftovers of `-instantsenddepth`

* Update manpages

* Install libxkbcommon0 in gitian-linux.yml

This fixes an issue reported by users on Ubuntu 18.04 LTS. They got the
following error message when starting dash-qt:

xkbcommon: ERROR: failed to add default include path auto
Qt: Failed to create XKB context!
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ':' as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see http://cgit.freedesktop.org/xkeyboard-config/ .

Dash-qt starts then, but does not accept any input from the keyboard.
The reason is that qt tries to find the xkb config root in the configure
phase, but fails to find it. To make this detection work, libxkbcommon
has to be installed on the host system, even though it is then never used.

* Fix issues in zh_CN

* Add platform dependent include_directories in CMakeLists.txt (#2455)

This gives much better auto-completion and code analysis in CLion.

Also add src/qt/forms to include path.

* Let ccache compress the cache by itself instead of compressing ccache.tar (#2456)

The cache can become quite large and uncompressing/recompressing it is slow.
Better to let ccache handle compression as it will then only perform it
on files which are actually used.

* Corrections to incorrect syntax in RPC help (#2466)

* Fix incorrect inline help for "protx update_registrar"

Initial ProRegTx does not define a field named "collateralAddress". It is not necessary to use the collateral address to receive payout, any Dash address can be defined here.

* Fix incorrect syntax for "protx revoke" inline help

"operatorKey" is required here

* Do not hold cs_main while emitting messages in WalletModel::prepareTransaction (#2463)

* Fix review comments

* Use ParseFixedPoint instead of ParseDoubleV in "protx register" commands (#2458)

* Few trivial fixes for DIP2/DIP3 (#2474)

* Fix wrong index for argument to protx_update_service when error is thrown

* Unify and fix variable name in TxToJSON

The UniValue variable name for TRANSACTION_COINBASE was wrong and is fixed
now. Also changed names for all other special TXs to unify names. This
should avoid such errors in the future when new "else if" branches are
copy/pasted.

* Use "proRegTx" instead of "proTx" as key TRANSACTION_PROVIDER_REGISTER payloads

* Forbid version=0 in special TXs (#2473)

* Base dsq/dstx thresholold on total number of up to date masternodes (#2465)

Mixing on a newer version with small number of upgraded masternodes
causes mixing txes to "stuck" - old nodes refuse to relay dstxes from new ones because
they come from the same masternodes too often. Basing threshold on the total number
of up to date masternodes and not only on a newer (enabled) ones should solve this.
This however will cause mixing to fail if there are not enough masternodes
on the needed protocol version (i.e. at least GetMinMasternodePaymentsProto())
but it's better to stop mixing than having funds kind of spent yet not confirmed
for a long time.

* Add univalue test for real numbers (#2460)

* Properly initialize confirmedHash in CSimplifiedMNListEntry (#2479)

* Properly initialize confirmedHash in CSimplifiedMNListEntry

* Add consensus params for temporary hard-fork on testnet

This hard-fork is required on testnet as we have to fix a few consensus
bugs in DIP3/DIP4. It will also be required to introduce LLMQ commitments
to testnet.

* Add temporary fork-logic for testnet, which sets confirmedHash to null

...before fork activation. Otherwise we'd invalidate all DIP3 blocks on
testnet.

* Bump nTemporaryTestnetForkHeight to 273000

* Fix filtering of the lock votes for SPV nodes. (#2468)

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of dashpay/dips#31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork

* Implement PoSe based on information from LLMQ commitments (#2478)

Members which are not in the validMembers bitsets are now PoSe punished.
The maximum PoSe score is dynamic and mostly identical to the number of
registered MNs. Added PoSe scores for failures are then a percentage of
the maximum score, so that we can better control how often failures are
allowed per payment cycle. For LLMQ failures, this is 66% to allow
approximately 2 failures per payment cycle.

* Bump nTemporaryTestnetForkHeight to 274000 (#2498)

* Perform less instant send tests in DIP3 tests (#2499)

These take quite some time on Travis.

* Try to fix a few sporadic instant send failures in DIP3 tests  (#2500)

* Sleep in wait_for_instant_lock when TX is not known yet

We'll otherwise stress the CPU quite a lot, which might in turn result in
instant send timeouts.

* Wait for all nodes to have the instant send lock

Otherwise individual nodes might end up not being able to catch up,
especially when it's the last iteration and we generate 6 blocks after it.

* Use getrawtransaction in wait_for_instant_lock instead of gettransaction

gettransaction fails if the TX is not owned by the wallet

* Give instant send tests more time after DIP3 activation

Signature verification changes to BLS when DIP3 gets activated, which is
much more resource hungry. Give instant send tests more time after DIP3
activation until we do proper batched verification of instant send
signatures.

* Disconnect peers with version < 70212 after DIP3 activation via BIP9 (#2497)

* Implement CDummyDKG and CDummyCommitment until we have the real DKG merged

This is only used on testnet/devnet/regtest and will NEVER be used on
mainnet. It is NOT SECURE AT ALL!

See comment in quorums_dummydkg.h for more details.

This reverts commit ebb120005292bc077d6dd7c4ce8adbe25167bf16.

* Put height into mined commitments and use it instead of the special handling of quorumVvecHash (#2501)

* Allow to skip sig verification for CFinalCommitment::Verify

* Add CFinalCommitmentTxPayload and CheckLLMQCommitment and use it

As described in dashpay/dips#31 (see discussion).

* Properly ban nodes for invalid commitments

* Add quorumModifierHash to instant send lock vote (#2505)

* Let GetMasternodeRank also return the block hash at the given height

* Add outpointConfirmedBlock to CTxLockVote and verify it

* Match order of parameters with member order

* Rename outpointConfirmedBlock to quorumModifierHash

* Add overload of GetMasternodeRank that does not return the block hash

* Fix crashes in "protx" RPCs when wallet is disabled (#2509)

* Fix check for nTemporaryTestnetForkDIP3Height (#2508)

This caused a crash when performing a full-sync.

* Use "registered" as default for "protx list" (#2513)

"wallet" was confusing too many users as it shows an empty list if the local
wallet does not own any keys for any MN.

* Deserialize CFinalCommitmentTxPayload instead of CFinalCommitment in TxToJSON (#2510)

* Deserialize CFinalCommitmentTxPayload instead of CFinalCommitment in TxToJSON

* Implement ToJson for CFinalCommitmentTxPayload and use it in TxToJSON

Otherwise the nVersion and nHeight members of it are not shown.

* Still support "protx list" and "protx diff" when wallet is disabled at compile time (#2511)

* Don't fully remove protx commands when ENABLE_WALLET is not set

* Check for wallet support at run-time for protx commands

* Only show subcommands that require the wallet when ENABLE_WALLET is set

* Add and use CheckWalletOwnsKey which is able to check wallet support at runtime

* Properly handle disabled wallets in "protx list"

This now also handles the case where ENABLE_WALLET is not defined.

* Drop comment that doesn't fully apply anymore

* Clear votes which were created before spork15 activation and use operator key for non-funding votes (#2512)

* Clear votes which were created before spork15 activation

* Reject incoming votes which were created pre-DIP3

* Only use voting keys for VOTE_SIGNAL_FUNDING

The other vote signals are meant to be emitted by sentinel and must thus
be signed with the operator key.

* Simplify GetMinVoteTime

* Review suggestions/fixes

* Add missing mutex in CGovernanceObject::RemoveOldVotes

* Print the state object when ProcessSpecialTxsInBlock fails in ConnectBlock (#2516)

Currently, when any DIP2/3/6 validation fails, there is no error message
printed that shows what exactly went wrong.

* Punish nodes which keep requesting and then rejecting blocks (#2518)

* Move deserialization of REJECT message fields out of if(fDebug)

* Ban nodes which keep requesting and then rejecting blocks

* Don't read/deserialize reject hash twice

* Only use ban score of 1

* Fix GUI warnings in debug.log (#2521)

Specifically:

```
GUI: QMetaObject::connectSlotsByName: No matching signal for on_extraInfoDIP3_doubleClicked()
GUI: QMetaObject::connectSlotsByName: No matching signal for on_copyProTxHash_clicked()
GUI: QMetaObject::connectSlotsByName: No matching signal for on_copyCollateralOutpoint_clicked()
```

* Call ProcessTick every second, handle tick cooldown inside (#2522)

* Bail out from GetBlockTxOuts in case nBlockHeight is above tip+1 (#2523)

In the future, we should make sure that this method is only called for the
currently mined block or for old blocks, but never for non-existing blocks
further in the future.

* Drop pre-DIP3 votes from current votes per MN per object (#2524)

* Avoid printing DIP3/DIP4 related logs twice (#2525)

All logging that happens in BuildNewListFromBlock is currently printed twice.
This is because BuildNewListFromBlock is called while processing the block
and also while calculating the DIP4 MN list commitment.

This commit adds the debugLogs to this method to allow omitting logs while
called from the DIP4 code.

* Fix multiple issues with governance voting after spork15 activation (#2526)

* Check resulting signature for validity when signing with BLS operator keys

* Support specifying proTxHash when using "gobject vote-alias"

The "alias-name" is now interpreted as proTxHash when deterministic MN lists
are active.

The classical "alias" as found in masternode.conf has no meaning after
spork15 activation.

* Don't use masternode.conf list in gobject_vote_many when spork15 is active

Keys don't match anymore so we should only rely on the deterministic list
and the local wallet's keys.

* Check for pwalletMain not being null in gobject_vote_many

* Allow to use vote-conf for non-proposal votes when spork15 is active

This fixes sentinel not being able to create triggers on testnet.

* Fix error message

* Fix no-wallet compilation and check for pwalletMain at runtime

* Don't respond with getdata for legacy inv types when spork15 is active (#2528)

Avoid unnecessary traffic from non-upgraded nodes.

* Also stop asking other peers for a TX when ProcessTxLockRequest fails (#2529)

This is moving up the RemoveAskFor call above the ProcessTxLockRequest
call. If ProcessTxLockRequest fails, we should not re-request the same
TX/IX from other nodes as it will continue to fail.

* Add dummy/hidden column to carry the proTxHash per MN list entry... (#2530)

...and use this in GetSelectedDIP3MN. This fixes copy/paste issues with MNs
that don't have a valid address (PoSe banned).

* Fix wrong total MN count in UI and "masternode count" RPC (#2527)

* Use CountMasternodes() in ClientModel::getMasternodeCountString

* Use CountMasternodes() for total count in masternode_count

* Fix CountMasternodes() to give correct number of masternodes with spork15 enabled

Also change CountEnabled to not call CountMasternodes anymore but instead
have its own implementation which uses GetValidMNsCount instead of GetAllMNsCount

* Apply review suggestions

* Allow filtering by proTxHash on DIP3 MN tab (#2532)

* Fix spork propagation while in IBD and fix spork integration tests (#2533)

* Fix spork syncing issue in sporks tests

dashpay/dash#2522 caused an issue with sporks syncing
in tests. The introduced time check in CMasternodeSync::ProcessTick causes
masternode sync to never start when mocktime is enabled, so this commit
disables mocktime for sporks.py.

Disabling mocktime however leads to fInitialDownload never becoming false
in CMasternodeSync::UpdatedBlockTip, so mnsync is never started. To fix
this, the tests now create a block before connecting the last node.

This however doesn't work because node1 will ignore the "getheaders" request
from node2 as it has not finished mnsync yet...so we also have to force
finish mnsync for node1.

* Also respond with getdata for announced sporks while in IBD

There was never a good reason to ignore spork announcements while in IBD.
At the same time, this poses the risk of missing out on sporks while in IBD.
This also fixes an issue in sporks testing, as nodes did not request for
announced sporks.

* Use wait_to_sync instead of custom loop

* Allow skipping of MN payments with zero duffs (#2534)

* Allow skipping of MN payments with zero duffs

In case a MNO uses an operator reward of 100%, the normal reward will be 0
duffs. It doesn't make sense to enforce these payments.

This will cause a fork when miners start to mine with the new version, but
only for nodes that didn't upgrade.

* Apply suggestions from code review

* Use correct time field when removing pre-DIP3 votes (#2535)

nTime is not the timestamp from the vote object. nCreationTime is the
correct field to use.

This fixes continues deletion of votes.

* Remove ProTxs from mempool that refer to a ProRegTx for which the collateral was spent (#2539)

* Track TXs in mempool which refer to an existing ProTx

* When a block is added, remove TXs that refer to ProTxs with spent collaterals

* Initalize evoDb and deterministicMNManager in BasicTestingSetup

instead of TestingSetup. Now that the mempool uses deterministicMNManager,
we need to initialize it for all tests that might use the mempool.

* Watch for changes in operator key and disable local MN (#2541)

* Introduce dummy (ping-like) contributions for the dummy DKG (#2542)

* Implement creation and propagation of dummy contributions

These act as a ping which is broadcast a few blocks before the dummy
commitments are created. They are meant to determine online/offline members.

* Use information about received dummy contributions to determine validMembers

* Fix PoSe tests

* Fix dummy DKG phase progress in PoSe tests and give tests more time

Mine one block at a time until we reach the mining phase.

* Reintroduce BLSInit to correctly set secure alloctor callbacks (#2543)

dashpay/dash#2409 removed the need to call the
Init method of the Chia BLS library, but we also accidently removed the
initialization of the secure allocator.

* Refactor CQuorumBlockProcessor and CDeterministicMNManager (#2536)

* Refactor CDeterministicMNManager::ProcessBlock: pintexPrev -> pindex->pprev and/or adjust logic accordingly

* Refactor CQuorumBlockProcessor::ProcessBlock: pintexPrev -> pindex->pprev and/or adjust logic accordingly

* Drop unused

* Don't delete/add values to the unique property map when it's null (#2538)

* Don't delete/add values to the unique property map when it's null

This happens when revoking operator keys, as the revoked MN will then have
the address and operator keys set to the null representation. We shouldn't
add the null value to the unique property map as otherwise future revokes
crash in an assert.

* Assert that no null values are passed to Add/DeleteUniqueProperty

* Check for null values before calling Add/DeleteUniqueProperty

* Ensure EvoDB consistency for quorum commitments by storing the best block hash (#2537)

* Ensure EvoDB consistency by storing the best block hash

This approach is similar to the one used for chainstate currently.
Ensures that:
- nodes that upgraded after DIP3 has all the data processed correctly (they will crash and require reindex);
- evodb/ is removed when blocks/ is removed (otherwise sync will fail due to duplicate records).

* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION to 70213 (#2557)

* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION to 70213

This will disconnect all nodes from the old testnet chain when DIP3 gets
