The use of PySys_GetObject() and _PySys_GetAttr(), which return a borrowed
reference, has been replaced by using one of the following functions, which
return a strong reference and distinguish a missing attribute from an error:
_PySys_GetOptionalAttr(), _PySys_GetOptionalAttrString(),
_PySys_GetRequiredAttr(), and _PySys_GetRequiredAttrString().

gh-129838: Don't redefine _Py_NO_SANITIZE_UNDEFINED (GH-129839)
Newer GCC versions accept both __attribute__((no_sanitize("undefined")))
and __attribute__((no_sanitize_undefined)) so check that the macro is
not already defined.

gh-129502: Fix handling errors in ctypes callbacks (GH-129504)
Unlikely errors in preparing arguments for ctypes callback are now
handled in the same way as errors raised in the callback of in converting
the result of the callback -- using sys.unraisablehook() instead of
sys.excepthook() and not setting sys.last_exc and other variables.

gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191)
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().
(cherry picked from commit 46c7e13c05)
tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(),
PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check
tracemalloc_config.tracing after calling TABLES_LOCK().
_PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(),
especially setting tracemalloc_config.tracing to 1.
Add a test using PyTraceMalloc_Track() to test tracemalloc.stop()
race condition.
Call _PyTraceMalloc_Init() at Python startup.

gh-127257: ssl: Raise OSError for ERR_LIB_SYS (GH-127361)
From the ERR_raise manpage:
ERR_LIB_SYS
This "library code" indicates that a system error is
being reported. In this case, the reason code given
to `ERR_raise()` and `ERR_raise_data()` *must* be
`errno(3)`.
This PR only handles ERR_LIB_SYS for the high-lever error types
SSL_ERROR_SYSCALL and SSL_ERROR_SSL, i.e., not the ones where
OpenSSL indicates it has some more information about the issue.

Since MultiByteToWideChar()/WideCharToMultiByte() is not reversible if
the data contains invalid UTF-8 sequences, use binary search to
calculate the number of written bytes from the number of written
characters.
Also fix writing incomplete UTF-8 sequences.
Also fix handling of memory allocation failures.

its state should be removed from interpreter' thread states list

The `methodcaller` C vectorcall implementation uses an arguments array
that is shared across calls. The first argument is modified on every
invocation. This isn't thread-safe in the free threading build. I think
it's also not safe in general, but for now just disable it in the free
threading build.
