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.
