[3.12] gh-103186: Fix or catch 'extra' stderr output from unittests (GH-103196) (#106605)
gh-103186: Fix or catch 'extra' stderr output from unittests (GH-103196)
Reduce test noise by fixing or catching and testing stderr messages from individual tests.
test_cmd_line_script.test_script_as_dev_fd calls spawn_python and hence subprocess.Popen with incompatible arguments. On POSIX, pass_fds forces close_fds to be True (subprocess.py line 848). Correct the call.
test_uuid.test_cli_namespace_required_for_uuid3: when the namespace is omitted, uuid.main calls argparse.Argument_Parser.error, which prints to stderr before calling sys.exit, which raises SystemExit. Unittest assertRaises catches the exception but not the previous output. Catch the output and test it.
test_warnings.test_catchwarnings_with_simplefilter_error similarly prints before raising. Catch the output and test it.

Clarify how topics.py gets created. (GH-106121)
When changing docs, it was easy to find text in topics.py, and I
wondered whether I was supposed to edit it. Thankfully, the top of the
file says it's auto-generated, so I knew I didn't have to edit it. But I
didn't know what started the auto-generation process.

Some items remained uninitialized if _sre.template() was called with invalid
indices. Then attempt to clear them in the destructor led to dereferencing
of uninitialized pointer.

gh-90876: Restore the ability to import multiprocessing when `sys.executable` is `None` (GH-106464)
Prevent `multiprocessing.spawn` from failing to *import* in environments
where `sys.executable` is `None`. This regressed in 3.11 with the addition
of support for path-like objects in multiprocessing.
Adds a test decorator to have tests only run when part of test_multiprocessing_spawn to `_test_multiprocessing.py` so we can start to avoid re-running the same not-global-state specific test in all 3 modes when there is no need.

This ensures that `commoninstall` is completed before `bininstall` is
started when parallel builds are used (`make -j install`), and so the
`python3` symlink is only installed after all standard library modules

[3.12] GH-106330: Fix matching of empty path in `pathlib.PurePath.match()` (GH-106331) (GH-106372)
We match paths using the `_lines` attribute, which is derived from the
path's string representation. The bug arises because an empty path's string
representation is `'.'` (not `''`), which is matched by the `'*'` wildcard.
