Disallow thread creation and fork at interpreter finalization.
in the following functions, check if interpreter is finalizing and raise `RuntimeError` with appropriate message:
* `_thread.start_new_thread` and thus `threading`
* `posix.fork`
* `posix.fork1`
* `posix.forkpty`
* `_posixsubprocess.fork_exec` when a `preexec_fn=` is supplied.

When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types.
We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.
Add ".. class::" markups in the wave documentation.
* Reformat also wave.py (minor PEP 8 changes).
* Remove redundant "import struct": it's already imported at top
level.
* Remove wave.rst from .nitignore
In gh-103912 we added tp_bases and tp_mro to each PyInterpreterState.types.builtins entry. However, doing so ignored the fact that both PyTypeObject fields are public API, and not documented as internal (as opposed to tp_subclasses). We address that here by reverting back to shared objects, making them immortal in the process.
`PurePath.match()` now handles the `**` wildcard as in `Path.glob()`, i.e. it matches any number of path segments.
We now compile a `re.Pattern` object for the entire pattern. This is made more difficult by `fnmatch` not treating directory separators as special when evaluating wildcards (`*`, `?`, etc), and so we arrange the path parts onto separate *lines* in a string, and ensure we don't set `re.DOTALL`.

Faster __repr__ with str.__add__ moved inside the f-string. For __eq__ comp;are field by field instead of building temporary tuples.

Subclassing `os.PathLike` rather than using `register()` makes
initialisation slower, due to the additional `__isinstance__` work.
This partially reverts commit bd1b6228d1.

Add a keyword-only *follow_symlinks* parameter to `pathlib.Path.glob()` and`rglob()`.
When *follow_symlinks* is `None` (the default), these methods follow symlinks except when evaluating "`**`" wildcards. When set to true or false, symlinks are always or never followed, respectively.
* gh-104497: Make tkinter test pass with tk 8.7
For test_widgets.MenuTest.test_configure_type, the options
in the error message change to alphabetical order.
* Update Lib/test/test_tkinter/test_widgets.py

Pass any ASAN_OPTIONS environment variable through to the child process
so that leak sanitizer being disabled on our CI and buildbots stays
true in the children.
For backwards compatibility, accept backslashes as path separators in
`PurePosixPath` if an instance of `PureWindowsPath` is supplied.
This restores behaviour from Python 3.11.

Use `str.lower()` rather than `ntpath.normcase()` to normalize case of
Windows paths. This restores behaviour from Python 3.11.

* Remove the Lib/test/imghdrdata/ directory.
* Copy 5 pictures (gif, png, ppm, pgm, xbm) from removed
Lib/test/imghdrdata/ to a new Lib/test/tkinterdata/ directory.
* Update Sphinx from 4.5 to 6.2 in Doc/requirements.txt.
Reduced _idle_semaphore.release calls in concurrent.futures.thread._worker
_idle_semaphore.release() is now only called if only work_queue is empty.

Wait until the thread spawn by the import completes to avoid dangling
threads. With this fix, the following command no longer fails:
./python -m test --fail-env-changed test_importlib -m test_side_effect_import -F -j20
In Python 3.8 and prior, `pathlib.Path.__exit__()` marked a path as closed;
some subsequent attempts to perform I/O would raise an IOError. This
functionality was never documented, and had the effect of making `Path`
objects mutable, contrary to PEP 428. In Python 3.9 we made `__exit__()` a
no-op, and in 3.11 `__enter__()` began raising deprecation warnings. Here
we remove both methods.
Having a separate lock means Thread.join() doesn't need to wait for the thread to be cleaned up first. It can wait for the thread's Python target to finish running. This gives us some flexibility in how we clean up threads.
(This is a minor cleanup as part of a fix for gh-104341.)
