gh-111777: Fix assertion errors on incorrectly still-tracked GC object destruction (GH-111778)
In PyObject_GC_Del, in Py_DEBUG mode, when warning about GC objects that
were not properly untracked before starting destruction, take care to
untrack the object _before_ warning, to avoid triggering a GC run and
causing the problem the code tries to warn about. Also make sure to save and
restore any pending exceptions, which the warning would otherwise clobber or
trigger an assertion error on.

Fix undefined behaviour in datetime.time.fromisoformat() (GH-111982)
Fix undefined behaviour in datetime.time.fromisoformat() when parsing a string without a timezone. 'tzoffset' is not assigned to by parse_isoformat_time if it returns 0, but time_fromisoformat then passes tzoffset to another function, which is undefined behaviour (even if the function in question does not use the value).

GH-111804: Drop posix.fallocate() under WASI (GH-111869)
Drop posix.fallocate() under WASI.
The underlying POSIX function, posix_fallocate(), was found to vary too
much between implementations to remain in WASI. As such, while it was
available in WASI preview1, it's been dropped in preview2.

gh-111881: Import doctest lazily in libregrtest (GH-111884)
In most cases, doctest is not needed. So don't always import it at
startup. The change reduces the number of modules already
imported when a test is run.

gh-111644: Fix asyncio test_unhandled_exceptions() (GH-111713)
Fix test_unhandled_exceptions() of test_asyncio.test_streams: break
explicitly a reference cycle.
Fix also StreamTests.tearDown(): the loop must not be closed
explicitly, but using set_event_loop() which takes care of shutting
down the executor with executor.shutdown(wait=True).
BaseEventLoop.close() calls executor.shutdown(wait=False).

gh-111644: Fix support threading_cleanup() (GH-111714)
Copy the list of dangling threads to make sure that the list of
"Dangling thread" is complete. Previously, the list was incomplete if
threads completed just before the list was displayed.
Changes:
* Rewrite the warning to make it easier to understand.
* Use support.sleeping_retry().
* threading_cleanup() no longer copies threading._dangling,
but only counts the number of dangling thread.
* Remove support.gc_support() call.
