Brings in the following changes
- Fix a bug when getting a gzip header extra field with
inflateGetHeader(). This remedies CVE-2022-37434.
- Fix a bug in block type selection when Z_FIXED used. Now the smallest
block type is selected, for better compression.
- Fix a configure issue that discarded the provided CC definition.
- Correct incorrect inputs provided to the CRC functions. This mitigates
a bug in Java.
- Repair prototypes and exporting of the new CRC functions.
- Fix inflateBack to detect invalid input with distances too far.
Mark zlib-1.2.12 as obsolete.

Bring in the following changes
- Fix a deflate bug when using the Z_FIXED strategy that can result in
out-of-bound accesses.
- Fix a deflate bug when the window is full in deflate_stored().
- Speed up CRC-32 computations by a factor of 1.5 to 3.
- Use the hardware CRC-32 instruction on ARMv8 processors.
- Speed up crc32_combine() with powers of x tables.
- Add crc32_combine_gen() and crc32_combine_op() for fast combines.
Drop two patches that have been applied upstream and regenerate the
remaining two.
