This adds basic support to override default messages for domain errors
in the math_1() helper. The sqrt(), atanh(), log2(), log10() and log()
functions were modified as examples. New macro supports gradual
changing of error messages in other 1-arg functions.

Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack()
during late Python finalization.
* Call _PyTraceMalloc_Fini() later in Python finalization.
* Test also PyTraceMalloc_Untrack() without the GIL
* PyTraceMalloc_Untrack() now gets the GIL.
* Test also PyTraceMalloc_Untrack() in test_tracemalloc_track_race().
This fixes UBSan failures for the following objects:
- `DictRemoverObject` and `StructParamObject`,
- `CDataObject` and `CFieldObject`, and
- `PyCFuncPtrObject` and `PyCArgObject`.
On the default build, we convert the `LOCK_PTR` and `UNLOCK_PTR` macros to
functions with an unused parameter to ease "unused variable" compiler warnings
suppression. Finally, we also remove some redundant casts to `PyObject *`.
Remove _PyInterpreterState_GetConfigCopy() and
_PyInterpreterState_SetConfig() private functions. PEP 741 "Python
Configuration C API" added a better public C API: PyConfig_Get() and
PyConfig_Set().
In the free threading build, the per thread reference counting uses a
unique id for some objects to index into the local reference count
table. Use 0 instead of -1 to indicate that the id is not assigned. This
avoids bugs where zero-initialized heap type objects look like they have
a unique id assigned.
Implement set_name() with SetThreadDescription() and _get_name() with
GetThreadDescription(). If SetThreadDescription() or
GetThreadDescription() is not available in kernelbase.dll, delete the
method when the _thread module is imported.
Truncate the thread name to 32766 characters.

tracemalloc_alloc(), tracemalloc_realloc(), tracemalloc_free(),
_PyTraceMalloc_TraceRef() and _PyTraceMalloc_GetMemory() now check
'tracemalloc_config.tracing' after calling TABLES_LOCK().
_PyTraceMalloc_TraceRef() now always returns 0.
* Use TABLES_LOCK() to protect 'tracemalloc_config.tracing'.
* Hold TABLES_LOCK() longer while accessing tables.
* tracemalloc_realloc() and tracemalloc_free() no longer
remove the trace on reentrant call.
* _PyTraceMalloc_Stop() unregisters _PyTraceMalloc_TraceRef().
* _PyTraceMalloc_GetTraces() sets the reentrant flag.
* tracemalloc_clear_traces_unlocked() sets the reentrant flag.
* ssl: Add hex error code to "unknown error" messages
To make it easier to vary the individual parts of the message,
replace the if-ladder with constant format strings by building
the string piece-wise with PyUnicodeWriter.
Use "unknown error (0x%x)" rather than just "unknown error" if we
can't get a better error message. (Hex makes sense as the error
includes two packed parts.)
This change, along with the LOAD_ATTR specializations, makes the
"thread_local_read" micro benchmark in Tools/ftscalingbench/ftscalingbench.py
scale well to multiple threads.
* Makes `_asyncio.Task` and `_asyncio.Future` thread-safe by adding critical sections
* Add assertions to check for thread safety checking locking of object by critical sections in internal functions
* Make `_asyncio.all_tasks` thread safe when eager tasks are used
* Add a thread safety test
