Cosmo's _Cz_crc32() function now goes 73 GiB/s on Threadripper. This will significantly improve the performance of the PKZIP file format. This algorithm is also used by apelink, to create deterministic ids. |

LOCAL CHANGES
- Use X86_HAVE() for runtime dispatching
- Changed Trace(stderr) calls to use kprintf()
- Made the type signature of crc32_z() less obnoxious
- Fix a Chromium Zlib regression where malloc() failures inside
deflateInit2() will result in a segmentation fault
- Provide THIRD_PARTY_ZLIB_GZ as a separate package, because it
can't work without malloc/stdio/etc. but the rest of zlib can
