* 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.

This can be tested by building with the Unix development build
make setup devel
make
or by building the freetype-demos programs with
meson setup build -Dfreetype2:zlib=internal
meson compile -C out
and trying to run `ftview` with a `.pcf.gz` font file.
* src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also
remove the temporary fix introduced in commit 6a431038 to work around the
fact that the internal sources were too old.
* src/gzip/README.freetype: New file describing the origin of the sources
and how they were modified.
* src/gzip/patches/*: Patch files applied to original sources.
* src/gzip/*: Updated zlib sources with the patch file(s) from
`src/gzip/patches/` applied, followed by a conversion with zlib's
`zlib2ansi` script.
