Victor Stinner 44378d46f6 Issue #11393: signal of user signal displays tracebacks even if tstate==NULL
* faulthandler_user() displays the tracebacks of all threads even if it is
   unable to get the state of the current thread
 * test_faulthandler: only release the GIL in test_gil_released() check
 * create check_signum() subfunction

Victor Stinner 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

Victor Stinner 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.

Victor Stinner 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.
