gh-144545: Improve handling of default values in Argument Clinic (GH-146016)
* Add the c_init_default attribute which is used to initialize the C variable
  if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default from
  default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
  over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII
  and non-printable characters and special characters like backslash or quotes).
* Fix support for str and bytes literals containing trigraphs, "/*" and "*/".
* Improve support for default values in converters "char" and "int(accept={str})".
* Converter "int(accept={str})" now requires 1-character string instead of
  integer as default value.
* Add support for non-None default values in converter "Py_buffer": NULL,
  str and bytes literals.
* Improve error handling for invalid default values.
* Rename Null to NullType for consistency.

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-99108: Add HACL* Blake2 implementation to hashlib (GH-119316)
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`.
