Increase support.LOOPBACK_TIMEOUT from 5 to 10 seconds. Also increase

test timeout of 40 minutes (ARM Raspbian 3.x), use LOOPBACK_TIMEOUT
of 20 seconds instead of 5 seconds before.

gh-110429: Fix race condition in "make regen-all" (GH-110433)
"make regen-pegen" now creates a temporary file called "parser.c.new"
instead of "parser.new.c". Previously, if "make clinic" was run in
parallel with "make regen-all", clinic may try but fail to open
"parser.new.c" if the temporay file was removed in the meanwhile.

gh-110167: Fix test_socket deadlock in doCleanups() (GH-110416)
Fix a deadlock in test_socket when server fails with a timeout but
the client is still running in its thread. Don't hold a lock to call
cleanup functions in doCleanups(). One of the cleanup function waits
until the client completes, whereas the client could deadlock if it
called addCleanup() in such situation.
doCleanups() is called when the server completed, but the client can
still be running in its thread especially if the server failed with a
timeout. Don't put a lock on doCleanups() to prevent deadlock between
addCleanup() called in the client and doCleanups() waiting for
self.done.wait of ThreadableTest._setUp().

Fix race conditions in test_threading lock tests. Wait until a
condition is met rather than using time.sleep() with a hardcoded
number of seconds.
* Replace sleeping loops with support.sleeping_retry() which raises
an exception on timeout.
* Add wait_threads_blocked(nthread) which computes a sleep depending
on the number of threads. Remove _wait() function.
* test_set_and_clear(): use a way longer Event.wait() timeout.
* BarrierTests.test_repr(): wait until the 2 threads are waiting for
the barrier. Use a way longer timeout for Barrier.wait() timeout.
* test_thread_leak() no longer needs to count
len(threading.enumerate()): Bunch uses
threading_helper.wait_threads_exit() internally which does it in
wait_for_finished().
* Add BaseLockTests.wait_phase() which implements a timeout.
test_reacquire() and test_recursion_count() use wait_phase().
* gh-109974: Fix more threading lock_tests race conditions (#110089)
* Add context manager on Bunch class.
* Bunch now catchs exceptions on executed functions and re-raise them
at __exit__() as an ExceptionGroup.
* Rewrite BarrierProxy.test_default_timeout(). Use a single thread.
Only check that barrier.wait() blocks for at least default timeout
seconds.
* test_with(): inline _with() function.
* Split test_pycfunction.py: add test_cfunction_full.py.
Split the function into the following 6 functions. In verbose
mode, these "pycfunction" tests now log each tested call.
* Move get_gdb_repr() to PrettyPrintTests.
* Replace DebuggerTests.get_sample_script() with SAMPLE_SCRIPT.
* Rename checkout_hook_path to CHECKOUT_HOOK_PATH.
* Rename gdb_version to GDB_VERSION_TEXT.
* Replace (gdb_major_version, gdb_minor_version) with GDB_VERSION.
* run_gdb() uses "backslashreplace" error handler instead of "replace".
* Add check_gdb() function to util.py.
* Enhance support.check_cflags_pgo(): check also for sysconfig
PGO_PROF_USE_FLAG (if available) in compiler flags.
* Move some SkipTest checks to test_gdb/__init__.py.
* Elaborate why gdb cannot be tested on Windows: gdb doesn't support
PDB debug symbol files.
* gh-104736: Fix test_gdb tests on ppc64le with clang (GH-109360)
Fix test_gdb on Python built with LLVM clang 16 on Linux ppc64le (ex:
Fedora 38). Search patterns in gdb "bt" command output to detect
when gdb fails to retrieve the traceback. For example, skip a test if
"Backtrace stopped: frame did not save the PC" is found.
* gh-110166: Fix gdb CFunctionFullTests on ppc64le clang build (GH-110331)
CFunctionFullTests now also runs "bt" command before "py-bt-full",
similar to CFunctionTests which also runs "bt" command before
"py-bt". So test_gdb can skip the test if patterns like "?? ()" are
found in the gdb output.

gh-109917: Fix test instability in test_concurrent_futures (GH-110306)
The test had an instability issue due to the ordering of the dummy
queue operation and the real wakeup pipe operations. Both primitives
are thread safe but not done atomically as a single update and may
interleave arbitrarily. With the old order of operations this can lead
to an incorrect state where the dummy queue is full but the wakeup
pipe is empty. By swapping the order in clear() I think this can no
longer happen in any possible operation interleaving (famous last
words).

gh-109960: Remove test_pty timeout of 10 seconds (GH-110058)
In 2003, test_pty got a hardcoded timeout of 10 seconds to prevent
hanging on AIX & HPUX "if run after test_openpty":
commit 7d8145268ee282f14d6adce9305dc3c1c7ffec14. Since 2003, test_pty
was no longer reported to hang on AIX. But today, the test can fail
simply because a CI is busy running other tests in parallel.
The timeout of 10 seconds is no longer needed, just remove it.
Moreover, regrtest now has multiple built-in generic timeout
mecanisms.
