* Try to fix asyncio.Server.wait_closed() again
I identified the condition that `wait_closed()` is intended
to wait for: the server is closed *and* there are no more
active connections.
When this condition first becomes true, `_wakeup()` is called
(either from `close()` or from `_detach()`) and it sets `_waiters`
to `None`. So we just check for `self._waiters is None`; if it's
not `None`, we know we have to wait, and do so.
A problem was that the new test introduced in 3.12 explicitly
tested that `wait_closed()` returns immediately when the server
is *not* closed but there are currently no active connections.
This was a mistake (probably a misunderstanding of the intended
semantics). I've fixed the test, and added a separate test that
checks exactly for this scenario.
I also fixed an oddity where in `_wakeup()` the result of the
waiter was set to the waiter itself. This result is not used
anywhere and I changed this to `None`, to avoid a GC cycle.

It now always returns an integer if one or less counting options are specified.
Previously it could return a single count as a 1-tuple, an integer (only if
option "update" was specified) or None if no items found.
The result is now the same if wantobjects is set to 0.
Fixes#109894
* set `interp.static_objects.last_resort_memory_error.args` to empty tuple to avoid crash on `PyErr_Display()` call
* allow `_PyExc_InitGlobalObjects()` to be called on subinterpreter init

Before, the '-s STRIPDIR' option on
compileall lead to some surprising results as it only strips away
path components that match, but leaves alone the non-matching ones
interspersed in between.
For example, with: python -m compileall -s/path/to/another/src
/path/to/build/src/file.py
The resulting written path will be: build/file.py
This fix only strips directories that are a fully matching prefix of the
source path. If a stripdir is provided that is not a valid prefix, a
warning will be displayed (which can be silenced with '-qq').
asyncio.TaskGroup and asyncio.Timeout classes now raise proper RuntimeError
if they are improperly used.
* When they are used without entering the context manager.
* When they are used after finishing.
* When the context manager is entered more than once (simultaneously or
sequentially).
* If there is no current task when entering the context manager.
They now remain in a consistent state after an exception is thrown,
so subsequent operations can be performed correctly (if they are allowed).

Test case matching patterns specified by options --match, --ignore,
--matchfile and --ignorefile are now tested in the order of
specification, and the last match determines whether the test case be run
or ignored.
Add PyUnicode_AsUTF8() function to the limited C API.
multiprocessing posixshmem now uses PyUnicode_AsUTF8() instead of
PyUnicode_AsUTF8AndSize(): the extension is built with the limited C
API. The function now raises an exception if the filename contains an
embedded null character instead of truncating silently the filename.
* PyUnicode_AsUTF8() now raises an exception if the string contains
embedded null characters.
* Update related C API tests (test_capi.test_unicode).
* type_new_set_doc() uses PyUnicode_AsUTF8AndSize() to silently
truncate doc containing null bytes.

Build the _multiprocessing.posixshmem extension with the Limited C
API.
* Add <errno.h> include.
* Replace PyUnicode_AsUTF8() with PyUnicode_AsUTF8AndSize().
* Replace PyStructSequence_SET_ITEM() with
PyStructSequence_SetItem().
* Replace PyTuple_GET_SIZE() with PyTuple_Size().
* Replace PyTuple_GET_ITEM() with PyTuple_GetItem().
Fix detection of gdb built without Python scripting support.
* check_usable_gdb() doesn't check gdb exit code when calling
run_gdb().
* Use shutil.which() to get the path to the gdb program.
The PySys_Audit() function was added in Python 3.8 by the PEP 578
"Python Runtime Audit Hooks".
Add also PySys_AuditTuple() to the limited C API, function added
to Python 3.13.
Move non-limited "PerfMap" C API from Include/sysmodule.h to
Include/cpython/sysmodule.h.
