Generate a build error on ``unguarded-availability`` in portable macOS builds (i.e. using MACOSX_DEPLOYMENT_TARGET), preventing invalid use of symbols that are not available in older versions of the OS.
Modifies _PYTHON_HOST_PLATFORM to include the compiler version under
Emscripten. The Emscripten compiler version is the platform version
compatibility identifier.
On Linux, threading.Thread now sets the thread name to the operating
system.
* configure now checks if pthread_getname_np()
and pthread_setname_np() functions are available.
* Add PYTHREAD_NAME_MAXLEN macro.
* Add _thread._NAME_MAXLEN constant for test_threading.

Moves the Emscripten web example into a standalone folder, and updates
Makefile targets to build the web example. Instructions for usage have
also been added.
This unifies the code for nodejs and the code for the browser. After this
commit, the browser example doesn't work; this will be fixed in a
subsequent update.
Before #126387, if we didn't detect float word order we'd raise the following
configure error:
Unknown float word ordering. You need to manually preset
ax_cv_c_float_words_bigendian=no (or yes) according to your system.
This puts it back (except for ARM or WASM, which as hardcoded).
Eventually wasm32-wasi will represent WASI 1.0, and so it's currently deprecated so it can be used for that eventual purpose. wasm32-wasip1 is also more specific to what version of WASI is currently supported.

The following variables are now used in compiler checks:
- $ac_cv_gcc_compat is set to 'yes' for GCC compatible compilers
(the C preprocessor defines the __GNUC__ macro)
- for compiler basename checks, use $CC_BASENAME
(may contain platform triplets)
- for the rest, use $ac_cv_cc_name
(does not contain platform triplets)
* Remove references to `Modules/_blake2`.
* Remove `Modules/_blake2` entry from CODEOWNERS
The folder does not exist anymore.
* Remove `Modules/_blake2` entry from `Tools/c-analyzer/TODO`
In Emscripten and other cross builds, the build file system and the host file
system look different. For instance, we may want to install into
`cross-build/$TARGET/lib`, and then mount that as `/lib` in the host file
system. This change adds a distinction between:
* `prefix` -- the path in the build file system where we want to install the files
* `host_prefix` -- the path in the host file system where getpath.c will look for the files
And similarly for `exec_prefix` and `host_exec_prefix`. At present, this is only
used for Emscripten.
Workaround for old libffi versions is added.
Module ctypes now supports C11 double complex only with libffi >= 3.3.0.

We previously used `AC_RUN_IF_ELSE` with a short test program to detect
if `-latomic` is needed, but that requires choosing a specific default
value when cross-compiling because the test program is not run.
Some cross compilation targets like `wasm32-emscripten` do not support
`-latomic`, while other cross compilation targets, like
`arm-linux-gnueabi` require it.

This replaces the existing hashlib Blake2 module with a single implementation that uses HACL\*'s Blake2b/Blake2s implementations. We added support for all the modes exposed by the Python API, including tree hashing, leaf nodes, and so on. We ported and merged all of these changes upstream in HACL\*, added test vectors based on Python's existing implementation, and exposed everything needed for hashlib.
This was joint work done with @R1kM.
See the PR for much discussion and benchmarking details. TL;DR: On many systems, 8-50% faster (!) than `libb2`, on some systems it appeared 10-20% slower than `libb2`.
