* gh-94949: Disallow parsing parenthesised ctx manager with old feature_version
* 📜🤖 Added by blurb_it.
* Allow it with feature_version=(3, 9) as well

Support for bytes broke sometime between Python 3.2 and 3.6 and has been broken ever since. Trying to bring back supports is surprisingly difficult in the face of -b and checking for keys in sys.path_importer_cache. Since the support was broken for so long, trying to overcome the difficulty of bringing back the support has been deemed not worth it.

* Add additional pointers to pathlib's mapping to os.path functions
os.path.splitext has a somewhat quirky signature since it mixes the path and filename components but I wanted the documentation to mention `PurePath.stem` as the natural counterpart to `PurePath.suffix` for the common use of `os.path.splitext` to turn "file.py" into "file" and "py".
Technically this could have some discussion of how to handle the parent directory hierarchy but that seems a bit out of keeping with the spirit of this table so I omitted mentioning `PurePath.parents` here.
* Update Doc/library/pathlib.rst

The case where there are more than (1 << 15) lines was not covered.
I don't know if increasing test coverage requires a blurb -- let me know if it does.

When binding a unix socket to an empty address on Linux, the socket is
automatically bound to an available address in the abstract namespace.
>>> s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
>>> s.bind("")
>>> s.getsockname()
b'\x0075499'
Since python 3.9, the socket is bound to the one address:
>>> s.getsockname()
b'\x00'
And trying to bind multiple sockets will fail with:
Traceback (most recent call last):
File "/home/nsoffer/src/cpython/Lib/test/test_socket.py", line 5553, in testAutobind
s2.bind("")
OSError: [Errno 98] Address already in use
Added 2 tests:
- Auto binding empty address on Linux
- Failing to bind an empty address on other platforms
Fixes f6b3a07b7d (bpo-44493: Add missing terminated NUL in sockaddr_un's length (GH-26866)
This makes calls to co_lnotab to exercise this code, as well
as generating synthetically large code to exercise the corner
cases where line numbers need multiple bytes.

The current status quo is that private attribute names are not
mangled when a class is matched. I've added a test to
document/legimize this behaviour.
