gh-90155: Fix bug in asyncio.Semaphore and strengthen FIFO guarantee (#93222)
The main problem was that an unluckily timed task cancellation could cause
the semaphore to be stuck. There were also doubts about strict FIFO ordering
of tasks allowed to pass.

The Semaphore implementation was rewritten to be more similar to Lock.
Many tests for edge cases (including cancellation) were added.

Revert "gh-87079: Warn on unintended signal wakeup fd override in asyncio (#96807)" (#96898)
This reverts commit 0587810698.
Reason: This broke buildbots (some warnings added by that commit are turned to errors in the SSL buildbot).
Repro:  ./python Lib/test/ssltests.py

gh-87079: Warn on unintended signal wakeup fd override in asyncio (#96807)
Warn on loop initialization, when setting the wakeup fd disturbs a previously set wakeup fd, and on loop closing, when upon resetting the wakeup fd, we find it has been changed by someone else.

GH-95704: Don't suppress errors from tasks when TG is cancelled (#95761)
When a task catches CancelledError and raises some other error,
the other error should not silently be suppressed.

Any scenario where a task crashes in cleanup upon cancellation
will now result in an ExceptionGroup wrapping the crash(es)
instead of propagating CancelledError and ignoring the side errors.

NOTE: This represents a change in behavior (hence the need to
change several tests).  But it is only an edge case.

GH-94398: TaskGroup: Fail create_task() during shutdown (GH-94400)
Once the task group is shutting down, it should not be possible to create a new task.
Here "shutting down" means `self._aborting` is set, indicating that at least one task
has failed and we have cancelled all others.

gh-84753: Make inspect.iscoroutinefunction() work with AsyncMock (#94050)
The inspect version was not working with unittest.mock.AsyncMock.

The fix introduces special-casing of AsyncMock in
`inspect.iscoroutinefunction` equivalent to the one
performed in `asyncio.iscoroutinefunction`.

gh-93852: Add test.support.create_unix_domain_name() (#93914)
test_asyncio, test_logging, test_socket and test_socketserver now
create AF_UNIX domains in the current directory to no longer fail
with OSError("AF_UNIX path too long") if the temporary directory (the
TMPDIR environment variable) is too long.

Modify the following tests to use create_unix_domain_name():

* test_asyncio
* test_logging
* test_socket
* test_socketserver

test_asyncio.utils: remove unused time import.

test_asyncio: run_until() implements exponential sleep (#93866)
run_until() of test.test_asyncio.utils now uses an exponential sleep
delay (max: 1 second), rather than a fixed delay of 1 ms. Similar
design than support.sleeping_retry() wait strategy that applies
exponential backoff.

gh-90978: asyncio TestSSL uses SHORT_TIMEOUT (#92642)
TestSSL of asyncio now uses support.SHORT_TIMEOUT rather than

gh-90978: test_ssl of test_asyncio uses LONG_TIMEOUT (#92402)
On slow buildbot workers, some test_ssl tests fail randomly because
of short timeout (30 seconds). Use support.LONG_TIMEOUT instead which
is longer and also adjusted (by regrtest --timeout option) on
buildbot workers known to be slow.

gh-82616: Add process_group support to subprocess.Popen (#23930)
One more thing that can help prevent people from using `preexec_fn`.

Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related.

gh-79156: Add start_tls() method to streams API (#91453)
The existing event loop `start_tls()` method is not sufficient for
connections using the streams API. The existing StreamReader works
because the new transport passes received data to the original protocol.
The StreamWriter must then write data to the new transport, and the
StreamReaderProtocol must be updated to close the new transport
correctly.

The new StreamWriter `start_tls()` updates itself and the reader
protocol to the new SSL transport.
