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.

gh-110367: Make regrtest --verbose3 compatible with --huntrleaks -jN (GH-111577)
"./python -m test -j1 -R 3:3 --verbose3" now works as expected, since
run_single_test() does not replace sys.stdout with StringIO in this
case.

gh-79033: Try to fix asyncio.Server.wait_closed() again (GH-111336)
* Try to fix asyncio.Server.wait_closed() again
I identified the condition that `wait_closed()` is intended
to wait for: the server is closed *and* there are no more
active connections.
When this condition first becomes true, `_wakeup()` is called
(either from `close()` or from `_detach()`) and it sets `_waiters`
to `None`. So we just check for `self._waiters is None`; if it's
not `None`, we know we have to wait, and do so.
A problem was that the new test introduced in 3.12 explicitly
tested that `wait_closed()` returns immediately when the server
is *not* closed but there are currently no active connections.
This was a mistake (probably a misunderstanding of the intended
semantics). I've fixed the test, and added a separate test that
checks exactly for this scenario.
I also fixed an oddity where in `_wakeup()` the result of the
waiter was set to the waiter itself. This result is not used
anywhere and I changed this to `None`, to avoid a GC cycle.
* Update Lib/asyncio/base_events.py

- `ThreadedChildWatcher.close()` is now *officially* a no-op; `_join_threads()` never did anything.
- Threads created by that class are now named `asyncio-waitpid-NNN`.
- `test.test_asyncio.utils.TestCase.close_loop()` now waits for the child watcher's threads, but not forever; if a thread hangs, it raises `RuntimeError`.

asyncio.TaskGroup and asyncio.Timeout classes now raise proper RuntimeError
if they are improperly used.
* When they are used without entering the context manager.
* When they are used after finishing.
* When the context manager is entered more than once (simultaneously or
sequentially).
* If there is no current task when entering the context manager.
They now remain in a consistent state after an exception is thrown,
so subsequent operations can be performed correctly (if they are allowed).
