[zlib] Re-sync with zlib 1.2.12, patch 15 of N

The last two changes came from the 'develop' branch of canonical
zlib and should address some issues on 1.2.12 that are going to
be featured on the upcoming 1.2.12.x.

With this patch landing, Chromium's zlib will be 1.2.12 + fixes
(plus our optimizations).

Ported:
 - Eliminate use of ULL constants.
 - Fix crc32.c to compile local functions only if used.
 - zlib 1.2.12
 - Silence some warnings from Visual Studio C.
 - Correct incorrect inputs provided to the CRC functions.
