libz sync with develop branch, discussed with deraadt

Apart from cosmetics, this includes the following commits:

Add LIT_MEM define to use more memory for a small deflate speedup.

A bug fix in zlib 1.2.12 resulted in a slight slowdown (1-2%) of
deflate. This commit provides the option to #define LIT_MEM, which
uses more memory to reverse most of that slowdown. The memory for
the pending buffer and symbol buffers is increased by 25%, which
increases the total memory usage with the default parameters by
about 6%.

Bump zlib version to 1.3

We have been pulling in all actual changes over the past months, so this
is only a version number bump. The relevant entries of the ChangeLog are:

* Building using K&R (pre-ANSI) function definitions is no longer supported.
* Fixed a bug in deflateBound() for level 0 and memLevel 9.
* Fixed a bug when gzungetc() is used immediately after gzopen().
* Fixed a bug when using gzflush() with a very small buffer.
* Fixed a crash when gzsetparams() is attempted for a transparent write.

This mostly moves from K&R prototypes to ANSI prototypes and includes a

will allow us to undo some hacks that jca applied to make the kernel build
with clang 15.

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.

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.
