This adds `_PyMem_FreeDelayed()` and supporting functions. The
`_PyMem_FreeDelayed()` function frees memory with the same allocator as
`PyMem_Free()`, but after some delay to ensure that concurrent lock-free
readers have finished.
<pycore_time.h> include is no longer needed to get the PyTime_t type
in internal header files. This type is now provided by <Python.h>
include. Add <pycore_time.h> includes to C files instead.
Restore support of such combination, disabled in gh-113796.
csv.writer() now quotes empty fields if delimiter is a space and
skipinitialspace is true and raises exception if quoting is not possible.
This avoids filling the memory occupied by ob_tid, ob_ref_local, and
ob_ref_shared with debug bytes (e.g., 0xDD) in mimalloc in the
free-threaded build.
This change adds an `eval_breaker` field to `PyThreadState`. The primary
motivation is for performance in free-threaded builds: with thread-local eval
breakers, we can stop a specific thread (e.g., for an async exception) without
interrupting other threads.
The source of truth for the global instrumentation version is stored in the
`instrumentation_version` field in PyInterpreterState. Threads usually read the
version from their local `eval_breaker`, where it continues to be colocated
with the eval breaker bits.
Keep the old private _PyCFunctionFastWithKeywords name (Python 3.7)
as an alias to the new public name PyCFunctionFastWithKeywords
(Python 3.13a4).
_PyCFunctionWithKeywords doesn't exist in Python 3.13a3, whereas
_PyCFunctionFastWithKeywords was removed in Python 3.13a4.
The charset name "Windows-31J" is registered in the IANA Charset Registry[1]
and is implemented in Python as the cp932 codec.

* test.bisect_cmd now exit with code 0 on success, and code 1 on
failure. Before, it was the opposite.
* test.bisect_cmd now runs the test worker process with
-X faulthandler.
* regrtest RunTests: Add create_python_cmd() and bisect_cmd()
methods.
Fix the exceptions raised by posixpath.commonpath
Raise ValueError, not IndexError when passed an empty iterable. Raise
TypeError, not ValueError when passed None.
It expects priority to be capped with 19, which is the cap for Linux,
but for FreeBSD the cap is 20 and the test fails under the similar
conditions. Tweak the condition to cover FreeBSD as well.
