gh-117953: Small Cleanup of Extensions-Related Machinery Code (gh-118167)
This is a collection of very basic cleanups I've pulled out of gh-118116. It is mostly renaming variables and moving a couple bits of code in functionally equivalent ways.
bpo-18108: Adding dir_fd and follow_symlinks keyword args to shutil.chown (GH-15811)
* Adding dir_fd and follow_symlinks keyword args to shutil.chown
* Extending test_shutil.TestShutil.test_chown to include new kwargs
* Updating shutil.chown documentation
gh-115961: Add name and mode attributes for compressed file-like objects (GH-116036)
* Add name and mode attributes for compressed and archived file-like objects
in modules bz2, lzma, tarfile and zipfile.
* Change the value of the mode attribute of GzipFile from integer (1 or 2)
to string ('rb' or 'wb').
* Change the value of the mode attribute of ZipExtFile from 'r' to 'rb'.

GH-112855: Speed up `pathlib.PurePath` pickling (#112856)
The second item in the tuple returned from `__reduce__()` is a tuple of arguments to supply to path constructor. Previously we returned the `parts` tuple here, which entailed joining, parsing and normalising the path object, and produced a compact pickle representation.
With this patch, we instead return a tuple of paths that were originally given to the path constructor. This makes pickling much faster (at the expense of compactness).
It's worth noting that, in the olden times, pathlib performed this parsing/normalization up-front in every case, and so using `parts` for pickling was almost free. Nowadays pathlib only parses/normalises paths when it's necessary or advantageous to do so (e.g. computing a path parent, or iterating over a directory, respectively).
gh-116818: Make `sys.settrace`, `sys.setprofile`, and monitoring thread-safe (#116775)
Makes sys.settrace, sys.setprofile, and monitoring generally thread-safe.
Mostly uses a stop-the-world approach and synchronization around the code object's _co_instrumentation_version. There may be a little bit of extra synchronization around the monitoring data that's required to be TSAN clean.
Before this PR tests decorated with a `requires_singlephase_init` helper
did not run because of an incorrect call to the `requires_gil_enabled`
helper.
gh-116931: Add fileobj parameter check for Tarfile.addfile (GH-117988)
Tarfile.addfile now throws an ValueError when the user passes
in a non-zero size tarinfo but does not provide a fileobj,
instead of writing an incomplete entry.
We were under-counting calls in `_PyEvalFramePushAndInit`
because the `CALL_STAT_INC` macro was redefined to a no-op
for the Tier 2 interpreter. The fix is not to `#undef` it at all.
This results in ~37% more "Frames pushed" reported
under "Call stats".
gh-87969: Align docs and docstrings with implementation for ctypes' [w]string_at() (#25384)
The implementation uses 'ptr' for the name of the first parameter of
ctypes.string_at() and ctypes.wstring_at(). Align docs and docstrings
with the naming used in the implementation.

gh-117657: Quiet erroneous TSAN reports of data races in `_PySeqLock` (#117955)
Quiet erroneous TSAN reports of data races in `_PySeqLock`
TSAN reports a couple of data races between the compare/exchange in
`_PySeqLock_LockWrite` and the non-atomic loads in `_PySeqLock_{Abandon,Unlock}Write`.
This is another instance of TSAN incorrectly modeling failed compare/exchange
as a write instead of a load.
gh-117657: Fix data races in the method cache in free-threaded builds (#117954)
Fix data races in the method cache in free-threaded builds
These are technically data races, but I think they're benign (to
the extent that that is actually possible). We update cache entries
non-atomically but read them atomically from another thread, and there's
nothing that establishes a happens-before relationship between the
reads and writes that I can see.

Test: Get the smtp test server using os.getenv() (#117979)
The smtp test server can be set via CPYTHON_TEST_SMTP_SERVER environment variable.
If not set, it uses the default value smtp.gmail.com
This is needed because the network I'm on filters access to
smtp.gmail.com resulting in a failing test.

gh-117845: Detect libedit hook function signature in configure (#117870)
Older libedit versions (like Apple's) use a different type signature
