This PR makes some minor linting adjustments to the Lib/test module
caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments
are all related to the `F541 f-string without any placeholders` issue.

This is strictly about moving the "obmalloc" runtime state from
`_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation
between interpreters, specifically most of the memory (incl. objects)
allocated for each interpreter's use. This is important for a
per-interpreter GIL, but such isolation is valuable even without it.
FWIW, a per-interpreter obmalloc is the proverbial
canary-in-the-coalmine when it comes to the isolation of objects between
interpreters. Any object that leaks (unintentionally) to another
interpreter is highly likely to cause a crash (on debug builds at
least). That's a useful thing to know, relative to interpreter
isolation.
sockserver gains ForkingUnixStreamServer and ForkingUnixDatagramServer classes for consistency with all of the others. Ironically these existed but were buried in our test suite.

This speeds up `super()` (by around 85%, for a simple one-level
`super().meth()` microbenchmark) by avoiding allocation of a new
single-use `super()` object on each use.
bpo-37222: Fix for CacheFTPHandler in urllib
A call to FTP.ntransfercmd must be followed by FTP.voidresp to clear
the "end transfer" message. Without this, the client and server get
out of sync, which will result in an error if the FTP instance is
reused to open a second URL. This scenario occurs for even the most
basic usage of CacheFTPHandler.
Reverts the patch merged as a resolution to bpo-16270 and adds a test
case for the CacheFTPHandler in test_urllib2net.py.

This is the implementation of PEP683
Motivation:
The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime.
Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
* bugfix: let the HTTP- and HTTPSHandlers respect the value of http.client.HTTPConnection.debuglevel
* add tests
* add news
* ReSTify NEWS and reword a bit.
* Address Review Comments.
* Use mock.patch.object instead of settting the module level value.
* Used test values to assert the debuglevel.

I recently added some tests to test_imp, but @warsaw is removing that file in gh-98573. The tests are worth keeping so here I'm moving them to test_import.
For example:
class Book(StrEnum):
title = auto()
author = auto()
desc = auto()
Book.author.desc is Book.desc
but
Book.author.title() == 'Author'
is commonly expected. Using upper-case member names avoids this confusion and possible performance impacts.

We no longer add a root to device paths such as `//./PhysicalDrive0`,
`//?/BootPartition` and `//./c:` while normalizing. We also avoid adding a
root to incomplete UNC share paths, like `//`, `//a` and `//a/`.

Fixes unittest.mock.patch not enforcing function signatures for methods
decorated with @classmethod or @staticmethod when patch is called with
autospec=True.
* gh-95299: Rework test_cppext.py to not invoke setup.py directly
* Add tests/cppextdata data to `TESTSUBDIRS`
* Revert "Add tests/cppextdata data to `TESTSUBDIRS`"
This reverts commit 635492e539.
* Revert "gh-95299: Rework test_cppext.py to not invoke setup.py directly"
This reverts commit 41c5a667b5.
* Build and install the extension in a temporary directory instead
* Pull in wheels for setuptools and wheel for testing extension builds
* The majority of the monitoring code is in instrumentation.c
* The new instrumentation bytecodes are in bytecodes.c
* legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs
Improve performance of path construction by skipping the addition of the path anchor (`drive + root`) to the internal `_parts` list. Rename this attribute to `_tail` for clarity.
* Quote paths in os.spawn tests on Windows so they work with spaces
* Add NEWS entry for os spawn test fix
* Fix code style to avoid double negative in os.spawn tests

The function is like Py_AtExit() but for a single interpreter. This is a companion to the atexit module's register() function, taking a C callback instead of a Python one.
We also update the _xxinterpchannels module to use _Py_AtExit(), which is the motivating case. (This is inspired by pain points felt while working on gh-101660.)
* bpo-22708: Upgrade HTTP CONNECT to protocol HTTP/1.1 (GH-NNNN)
Use protocol HTTP/1.1 when sending HTTP CONNECT tunnelling requests;
generate Host: headers if one is not already provided (required by
HTTP/1.1), convert IDN domains to punycode in HTTP CONNECT requests.
* Refactor tests to pass under -bb (fix ByteWarnings); missed some lines >80.
* Use consistent 'tunnelling' spelling in Lib/http/client.py
* Lib/test/test_httplib: Remove remnant of obsoleted test.
* Use dict.copy() not copy.copy()
* fix version changed
* Update Lib/http/client.py

Fix an issue where `__new__()` and `__init__()` were not called on subclasses of `pathlib.PurePath` and `Path` in some circumstances.
Paths are now normalized on-demand. This speeds up path construction, `p.joinpath(q)`, and `p / q`.
