Issue #23836 : Fix the faulthandler module to handle reentrant calls
...
to its signal handlers.
Use also _Py_write_noraise() instead of write() to retry write() if it is
interrupted by a signal (fail with EINTR).
faulthandler.dump_traceback() also calls PyErr_CheckSignals() to call the
Python signal handler if a signal was received.

(Merge 3.4) faulthandler: test_gil_released() now uses _sigsegv() instead of
...
_read_null(), because _read_null() cannot be used on AIX. On AIX, reading from
NULL is allowed: the first page of memory is a mapped read-only on AIX.
_read_null() and _sigabrt() don't accept parameters.

faulthandler: dump all threads by default
...
* Set the default value of all_threads arguments to True
* Py_FatalError() dumps all threads, instead of only the current thread
Dump only the current thread is not reliable. In some cases, Python is unable
to retrieve the state of the current thread and so is unable to dump the
traceback. faulthandler keeps a reference to the interpreter and so is always
able to dump the traceback of all threads.

* 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.
