README: Update bin sizes for 2.9.5.

Signed-off-by: Paul Sokolovsky <[email protected]>

.gitignore: Ignore archive, map, and executable files

defl_static: Get rid of "code" field in len_coderecord altogether.

Saves 88 bytes on ARM.

defl_static.h: Add license blurb.

These can be considered to be "automatically generated metadata", and
also were changed in noticeable ways comparing to original Simon Tatham's
code, so not trying to make a claim that these are copyright by him.
Instead, just use the generic copyright notice and the license of the
uzlib project.

README: Update bin sizes for 2.9.1.

Makefile: Add top-level makefile to build/clean everything.

tinflate: Explicitly get length/invlength as little-endian.

Previosuly, the statements looked like:

length = uzlib_get_byte(d) + 256 * uzlib_get_byte(d);

But the C standard doesn't define in which order function calls are made,
and different compilers/their options may use different order. So, break
the statement above in two, to guarantee the proper computation order.

Reported in #8.

tinflate: When using sliding dictionary, check that offset lies withi…

…n it.

tinfgzip: Fixes for pedantic compiler warnings.

adler32, crc32: Consistently use stdint types.
