zstd

Update bundled libzstd to 1.5.7

Wheel for linux are here and pipy (built on Ubuntu xenial, gcc-5, manylinux_2_14)

• Make decompression of zstd stream data possible #228 and #100

Wheel for python3.12 amd64 uploaded here

• support of multiple instances of interpreter with own GIL by @domysh

• fix module version string form then building with external system library #203

• find pkg-config in paths defined in PATH environment variable, as suggested by @parona-source
• add new options for development --all-warnings and --all-warnings-errors
• fix action setup for building wheels

• fixed check() function
• fixed various compiller warnings
• added some developer/debug options for compilation

• add missing definitions of multithreading and external library flags
• add new information function about legacy formats support
• fix building with external system library
• added an strict mode to compression function, to no make exception if level or threads count are beyond limitations

Broken check() function

• Add new functions:check(), ZSTD_with_threads(), ZSTD_with_asm()
• fix possible error with null dereference, thanks to @danielg4
• build extension with multi threads and using ASM by default
• fix github actions, build wheels for macos

Broken build with external libzstd.

Update action to genegate wheels

• Update bundled libzstd to 1.5.5
• Fix decompression of multiple concatenated frames in one input string

Wheels

• Generic automated builds are pushed to PyPi.
• x86 and x64 builded under Ubuntu 16.04. And with sse+sse2 optimizations enabled via compiler.
• armhf and arm64 builded under Ubuntu 18.04.
• armhf builded on Raspberry PI 2B and optimized for it.
• arm64 builded on Raspberry PI 4B and optimized for it.
• PyPy builds on arm64 missing 2.7 as it are broken.
• MacOsX builds done inside 11.7 hackintosh

Don't fail with exception if defined number of threads to compress is bigger than libzstd can take. Silently drop it value down to max threads.

Description

Fix a nasty bug - corrupted compression of empty string, and decompression too. Thanks to @nepeat

Add support of setting build options via envvars - PEP 517 compat. Thanx to @mgorny

Changes

Fix tests strings.

Nothing else ~matters~ changed.

Quick fix for build via pypy3.9 - they not implemented bpo-40421 in full.
