gh-134696: align OpenSSL and HACL*-based hash functions constructors AC signatures (#134713) 
OpenSSL and HACL*-based hash functions constructors now support both `data` and `string` parameters.
Previously these constructor functions inconsistently supported sometimes `data` and sometimes `string`,
while the documentation expected `data` to be given in all cases.

gh-131418: remove unused legacy typedefs in {md5,sha1}module.c (#131420) 
- Remove legacy typedefs `MD5_INT32` and `MD5_INT64` in `Modules/md5module.c`
- Remove legacy typedefs `SHA1_INT32` and `SHA1_INT64` in `Modules/sha1module.c`.

Those legacy typedefs were used to detect whether the host platform could
correctly implement MD5 and SHA-1, but this is no longer needed as we now
fallback to HACL* implementations.

Cosmetics:

- suppress unused return values
- remove redundant casts in constructors
- suppress unused parameters in `{md5,sha*,blake2}module.c`

gh-116322: Add Py_mod_gil module slot (#116882) 
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).

gh-99108: Release the GIL around hashlib built-in computation (#104675)

purpose and explain the lock strategy in both existing and new code.

bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157) 
setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every
module defines the macro before #include "Python.h" unless
Py_BUILD_CORE_BUILTIN is already defined.

Py_BUILD_CORE_BUILTIN is defined for every module that is built by
Modules/Setup.

The PR also simplifies Modules/Setup. Makefile and makesetup
already define Py_BUILD_CORE_BUILTIN and include Modules/internal
for us.

7cad53e6b0 bpo-9216: Add usedforsecurity to hashlib constructors (GH-16044) 
The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes.  Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it.
