gh-109521: Fix obscure cases handling in PyImport_GetImporter() (GH-109522)
PyImport_GetImporter() now sets RuntimeError if it fails to get sys.path_hooks
or sys.path_importer_cache or they are not list and dict correspondingly.
Previously it could return NULL without setting error in obscure cases,
crash or raise SystemError if these attributes have wrong type.

gh-109582: test_fork_signal_handling should wait for event (GH-109605)
Sometimes the child_handled event was missing because either
the child quits before it gets a chance to handle the signal,
or the parent asserts before the event notification is
delivered via IPC. Synchronize explicitly to avoid this.

gh-109613: _pystat_fromstructstat() checks for exceptions (GH-109618)
Fix os.stat() and os.DirEntry.stat(): check for exceptions.
Previously, on Python built in debug mode, these functions could
trigger a fatal Python error (and abort the process) when a function
succeeded with an exception set.
_pystat_fromstructstat() now exits immediately if an exception is
raised, rather only checking for exceptions at the end. It fix
following fatal error in fill_time():
Fatal Python error: _Py_CheckSlotResult:
Slot * of type int succeeded with an exception set

gh-103053: Skip test_freeze_simple_script() on PGO build (#109591)
Skip test_freeze_simple_script() of test_tools.test_freeze if Python
is built with "./configure --enable-optimizations", which means with
Profile Guided Optimization (PGO): it just makes the test too slow.
The freeze tool is tested by many other CIs with other (faster)
compiler flags.
test.pythoninfo now gets also get_build_info() of
test.libregrtests.utils.

gh-108973: Fix asyncio test_subprocess_consistent_callbacks() (GH-109431)
SubprocessProtocol process_exited() method can be called before
pipe_data_received() and pipe_connection_lost() methods. Document it
and adapt the test for that.
Revert commit 282edd7b2a.
_child_watcher_callback() calls immediately _process_exited(): don't
add an additional delay with call_soon(). The reverted change didn't
make _process_exited() more determistic: it can still be called
before pipe_connection_lost() for example.

gh-107219: Fix concurrent.futures terminate_broken() (GH-109244)
Fix a race condition in concurrent.futures. When a process in the
process pool was terminated abruptly (while the future was running or
pending), close the connection write end. If the call queue is
blocked on sending bytes to a worker process, closing the connection
write end interrupts the send, so the queue can be closed.
Changes:
* _ExecutorManagerThread.terminate_broken() now closes
call_queue._writer.
* multiprocessing PipeConnection.close() now interrupts
WaitForMultipleObjects() in _send_bytes() by cancelling the
overlapped operation.
