Issue #22818: Splitting on a pattern that could match an empty string now
raises a warning. Patterns that can only match empty strings are now
rejected.

Issue #22445: PyBuffer_IsContiguous() now implements precise contiguity
tests, compatible with NumPy's NPY_RELAXED_STRIDES_CHECKING compilation
flag. Previously the function reported false negatives for corner cases.

Issue #23353: Fix the exception handling of generators in PyEval_EvalFrameEx().
At entry, save or swap the exception state even if PyEval_EvalFrameEx() is
called with throwflag=0. At exit, the exception state is now always restored or
swapped, not only if why is WHY_YIELD or WHY_RETURN. Patch co-written with
Antoine Pitrou.

Issue #23347, asyncio: send_signal(), terminate(), kill() don't check if the
transport was closed. The check broken a Tulip example and this limitation is
arbitrary. Check if _proc is None should be enough.
Enhance also close(): do nothing when called the second time.

Issue #23347: send_signal(), kill() and terminate() methods of
BaseSubprocessTransport now check if the transport was closed and if the
process exited.
Issue #23347: Refactor creation of subprocess transports. Changes on
BaseSubprocessTransport:
* Add a wait() method to wait until the child process exit
* The constructor now accepts an optional waiter parameter. The _post_init()
coroutine must not be called explicitly anymore. It makes subprocess
transports closer to other transports, and it gives more freedom if we want
later to change completly how subprocess transports are created.
* close() now kills the process instead of kindly terminate it: the child
process may ignore SIGTERM and continue to run. Call explicitly terminate()
and wait() if you want to kindly terminate the child process.
* close() now logs a warning in debug mode if the process is still running and
needs to be killed
* _make_subprocess_transport() is now fully asynchronous again: if the creation
of the transport failed, wait asynchronously for the process eixt. Before the
wait was synchronous. This change requires close() to *kill*, and not
terminate, the child process.
* Remove the _kill_wait() method, replaced with a more agressive close()
method. It fixes _make_subprocess_transport() on error.
BaseSubprocessTransport.close() calls the close() method of pipe transports,
whereas _kill_wait() closed directly pipes of the subprocess.Popen object
without unregistering file descriptors from the selector (which caused severe
bugs).
These changes simplifies the code of subprocess.py.

connection is cancelled, by a timeout for example.
