* src/gzip/ftgzip.c (HAVE_HIDDEN): Do not define; it is no longer needed
because everything is static.
(HAVE_MEMCPY): Define.
(zcalloc, zcfree): Remove no longer needed definitions (because `Z_SOLO` is
active).
* src/gzip/patches/freetype-zlib.diff: Regenerated.
Fixes#1146.

Description:
"A massively spiffy yet delicately unobtrusive compression library."
'zlib' is a free, general-purpose, legally unencumbered lossless
data-compression library. 'zlib' implements the "deflate"compression
algorithm described by RFC 1951, which combines the LZ77 (Lempel-Ziv)
algorithm with Huffman coding. zlib also implements the zlib (RFC 1950) and
gzip (RFC 1952) wrapper formats.
Local Modifications:
The files in this directory have been prepared as follows.
- Take the unmodified source code files from the zlib distribution that are
included by `ftgzip.c`.
- Copy `zconf.h` to `ftzconf.h` (which stays unmodified otherwise).
- Run zlib's `zlib2ansi` script on all `.c` files.
- Apply the diff file(s) in the `patches` folder.
