In Lexical Analysis f-strings section, NULL in the description
of 'literal character' means '\0'. In the format_spec grammar
production, it is wrong with that meaning and redundant if
instead interpreted as <nothing>. Remove it there.

It is confusing, because libc is not imported from ctypes,
but defined in previous examples, which already contain the import.

test_match_tests now saves and restores patterns.
Add get_match_tests() function to libregrtest.filter.

tests once: "./python -m test test_regrtest -R 3:3.

[3.11] gh-116307: Proper fix for 'mod' leaking across importlib tests (GH-116680)
(cherry picked from commit a254807761)
gh-116307: Create a new import helper 'isolated modules' and use that instead of 'Clean Import' to ensure that tests from importlib_resources don't leave modules in sys.modules.
If the `shutdown()` call happens before the worker thread starts executing
the task, then nothing will be printed to stdout.

gh-71052: Use `raise_signal` in `ThreadSignals.test_signals` (GH-116423)
Use `raise_signal` rather than `kill` in `ThreadSignals.test_signals`
(cherry picked from commit 34920f3691)
Co-authored-by: Malcolm Smith <smith@chaquo.com>
This backports:
- GH-115813
- GH-115422
Unlike on the main branch, new directories are added to the end,
so they're a bit easier to patch out if a redistributor needs to do so.
On main & 3.12, there's a special case for `idlelib/idle_test`; on
3.11 TESTSUBDIRS has several more entries that are not in `test/`.
This backport ignores all of them (including idlelib).
(The alternative would be list them, as additions to TEST_HOME_DIR.
But that's probably too invasive; people might split stdlib up in
surprising ways.)

The tests failed (with less than 1% probability) if for example the file
was created at 11:46:03.999, but the record was emitted at 11:46:04.001,
with atTime=11:46:04, which caused an unexpected rollover. Ensure that the
tests are always run within the range of the same whole second.
Also share code between test_rollover_at_midnight and test_rollover_at_weekday.

Fix some test_multiprocessing flakiness.
Potentially introduced by https://github.com/python/cpython/pull/25845
not joining that thread likely leads to recently observed "environment
changed" logically passing but overall failing tests seen on some
buildbots similar to:
```
1 test altered the execution environment (env changed):
test.test_multiprocessing_fork.test_processes
2 re-run tests:
test.test_multiprocessing_fork.test_processes
test.test_multiprocessing_forkserver.test_processes
```

Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425) by adding five new methods:
- `xml.etree.ElementTree.XMLParser.flush`
- `xml.etree.ElementTree.XMLPullParser.flush`
- `xml.parsers.expat.xmlparser.GetReparseDeferralEnabled`
- `xml.parsers.expat.xmlparser.SetReparseDeferralEnabled`
- `xml.sax.expatreader.ExpatParser.flush`
Based on the "flush" idea from #115138 (comment) .
- Please treat as a security fix related to CVE-2023-52425.
