* Raise PicklingError instead of UnicodeEncodeError, ValueError
and AttributeError in both implementations.
* Chain the original exception to the pickle-specific one as __context__.
* Include the error message of ImportError and some AttributeError in
the PicklingError error message.
* Unify error messages between Python and C implementations.
* Refer to documented __reduce__ and __newobj__ callables instead of
internal methods (e.g. save_reduce()) or pickle opcodes (e.g. NEWOBJ).
* Include more details in error messages (what expected, what got).
* Avoid including a potentially long repr of an arbitrary object in
error messages.
* protect macros expansion via `do { ... } while (0)` constructions in `_decimal.c`
* Use public macro `Py_UNUSED`
This replaces the usages of the `UNUSED` macro which
was not consistent with the `Py_UNUSED` macro itself.
In addition, this amends the parameter names so that
they match their semantic meanings.
* Remove redundant `PyCFunction` casts
Add PyConfig_Get(), PyConfig_GetInt(), PyConfig_Set() and
PyConfig_Names() functions to get and set the current runtime Python
configuration.
Add visibility and "sys spec" to config and preconfig specifications.
_PyConfig_AsDict() now converts PyConfig.xoptions as a dictionary.

Switch more _Py_IsImmortal(...) assertions to _Py_IsImmortalLoose(...)
The remaining calls to _Py_IsImmortal are in free-threaded-only code,
initialization of core objects, tests, and guards that fall back to
code that works with mortal objects.
This checks are redundant in normal circumstances and can only work if
the extension registry was intentionally broken.
* The Python implementation now raises exception for the extension code
with false boolean value.
* Simplify the C code. RuntimeError is now raised in explicit checks.
* Add many tests.
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`.
There were a still a number of gaps in the tests, including not looking
at all the builtin types and not checking wrappers in subinterpreters
that weren't in the main interpreter. This fixes all that.
I considered incorporating the names of the PyTypeObject fields
(a la gh-122866), but figured doing so doesn't add much value.
* Parameters after the var-positional parameter are now keyword-only
instead of positional-or-keyword.
* Correctly calculate min_kw_only.
* Raise errors for invalid combinations of the var-positional parameter
with "*", "/" and deprecation markers.
Return -1 and set an exception on error; return 0 if the iterator is
exhausted, and return 1 if the next item was fetched successfully.
Prefer this API to PyIter_Next(), which requires the caller to use
PyErr_Occurred() to differentiate between iterator exhaustion and errors.

Fix _PyArg_UnpackKeywordsWithVararg for the case when argument for
positional-or-keyword parameter is passed by keyword.
There was only one such case in the stdlib -- the TypeVar constructor.
Fix PyEval_GetLocals() to avoid SystemError ("bad argument to
internal function"). Don't redefine the 'ret' variable in the if
block.
Add an unit test on PyEval_GetLocals().
