ce16be91dc (Merge 3.2) Issue #11768: The signal handler of the signal module only calls 
Py_AddPendingCall() for the first signal to fix a deadlock on reentrant or
parallel calls. PyErr_SetInterrupt() writes also into the wake up file.

a4de6d885f Improve faulthandler.enable(all_threads=True) 
faulthandler.enable(all_threads=True) dumps the tracebacks even if it is not
possible to get the state of the current thread

Create also the get_thread_state() subfunction to factorize the code.

de10f4054b faulthandler: one more time, fix usage of locks in the watchdog thread 
* Write a new test to ensure that dump_tracebacks_later() still works if
   it was already called and then cancelled before
 * Don't use a variable to check the status of the thread, only rely on locks
 * The thread only releases cancel_event if it was able to acquire it (if
   the timer was interrupted)
 * The main thread always hold this lock. It is only released when
   faulthandler_thread() is interrupted until this thread exits, or at Python
   exit.

da9edae1f4 Issue #11753: faulthandler thread uses pthread_sigmask() 
The thread must not receive any signal. If the thread receives a signal,
sem_timedwait() is interrupted and returns EINTR, but in this case,
PyThread_acquire_lock_timed() retries sem_timedwait() and the main thread is
not aware of the signal. The problem is that some tests expect that the main
thread receives the signal, not faulthandler handler, which should be
invisible.

On Linux, the signal looks to be received by the main thread, whereas on
FreeBSD, it can be any thread.

f309134eff Issue #11393: fix usage of locks in faulthandler 
* faulthandler_cancel_dump_tracebacks_later() is responsible to set running
   to zero (so we don't need the volatile keyword anymore)
 * release locks if PyThread_start_new_thread() fails

assert(thread.running == 0) was wrong in a corner case

a4d4f1b4cb Issue #11393: New try to fix faulthandler_thread() 
Always release the cancel join.

Fix also another corner case: _PyFaulthandler_Fini() called after setting
running variable to zero, but before releasing the join lock.

1c76b7f5e5 Issue #11393: Fix faulthandler_thread(): release cancel lock before join lock 
If the thread releases the join lock before the cancel lock, the thread may
sometimes still be alive at cancel_dump_tracebacks_later() exit. So the cancel
lock may be destroyed while the thread is still alive, whereas the thread will
try to release the cancel lock, which just crash.

Another minor fix: the thread doesn't release the cancel lock if it didn't
acquire it.
