zlib: sync with upstream

More Windows #ifdef shuffling. Only one change relevant for OpenBSD:
Make deflateBound() more conservative and handle Z_STREAM_END.

libz: sync with upstream

- fix type of local variable in deflate_stored()
- more Windows compat shuffling
- wrap overlong line in gzread

pull in another upstream tweak for windows

sync with upstream

Update to zlib 1.3.1

Since we already pulled in all fixes, this only bumps version/magic numbers
and copyright years. The fixes relevant to OpenBSD are:

- Fix bug in inflateSync() for data held in bit buffer
- Add LIT_MEM define to use more memory for a small deflate speedup
- Add bounds checking to ERR_MSG() macro, used by zError()
- Various portability and appearance improvements

libz: sync with upstream's develop branch as of Jan 18

Pull in two #undef from upstream's develop branch

ok guenther

Update libz to the HEAD of the develop branch

This mostly moves from K&R prototypes to ANSI prototypes and includes a
handful of bug fixes that are nice to have. The corresponding sys commit
will allow us to undo some hacks that jca applied to make the kernel build
with clang 15.

Drop RCS ids in upstream zlib source

We're not maintaining a this as a fork, it's upstream source with a handful
of patches. Thus, the RCS ids aren't particularly useful or important. They
are a bit of a maintenance burden and generate noise in diffs.

Update to zlib 1.2.12

Build tests by myself for amd64 and arm64, sthen and inoguchi for i386
and gkoehler for macppc and powerpc64, thanks!

Detailed changelog is part of the committed diff.

Add missing RCS tags

Update libz to zlib 1.2.11 and reapply local patches as far as this
made sense.

Tested in snaps for a few days. deraadt helped with fitting things on
floppies and jmatthew found a bug I introduced.
