Bug #317 - add fuzzing.h to dist

This should fix parallel build.

add tcpreplay_opts.h to list of BUILT_SOURCES

improve fuzzing documentation

Bug #329 fix -l0 print logic

The option `--fuzz-seed` feeds the system's random seed. Although this produces consistent results between runs on a given platform, results will be inconsistent on other platforms. Therefore a test cannot be produced tht is multi-platform.

Alternately a separate random number generated could be implemented, bypassing the system. This would ensure consistency across platforms.

Bug #316 fuzz test fails osx

-O3 can have adverse effects and may result in slower code, so users should be able to set and/or override it in USER_CFLAGS.

* Enhancement #334 - Fix warnings on debug

Latest changes caused multiple declarations of $VERSION and $PRODUCT, which caused `configure` test failures. The result was that tests failed where they otherwise would pass. Result was `-Wno-format-contains-nul` was not defined.

Fix is to remove effectively duplicate declarations of the within `configure.ac`.

* Enhancement #334 - fix build error

For example, this means :
- skipping TCP SYN packets
- no ethertype, ip addresses, not port number will be modified
