f7d090c165 bpo-30796: Fix failures in signal delivery stress test (#2488) 
* bpo-30796: Fix failures in signal delivery stress test

setitimer() can have a poor minimum resolution on some machines,
this would make the test reach its deadline (and a stray signal
could then kill a subsequent test).

* Make sure to clear the itimer after the test

32eb840a42 Issue #26566: Rewrite test_signal.InterProcessSignalTests 
* Add Lib/test/signalinterproctester.py
* Don't disable the garbage collector anymore
* Don't use os.fork() with a subprocess to not inherit existing signal handlers
  or threads: start from a fresh process
* Don't use UNIX kill command to send a signal but Python os.kill()
* Use a timeout of 10 seconds to wait for the signal instead of 1 second
* Always use signal.pause(), instead of time.wait(1), to wait for a signal
* Use context manager on subprocess.Popen
* remove code to retry on EINTR: it's no more needed since the PEP 475
* remove unused function exit_subprocess()
* Cleanup the code

38c707e7e0 Issue #21741: Update 147 test modules to use test discovery. 
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.

749a6a85c6 Issue #23485: Fix test_signal, select.select() now retries the syscall if the 
signal handler does not raise an exception

a453cd8d85 Issue #23715: signal.sigwaitinfo() and signal.sigtimedwait() are now retried 
when interrupted by a signal not in the *sigset* parameter, if the signal
handler does not raise an exception. signal.sigtimedwait() recomputes the
timeout with a monotonic clock when it is retried.

Remove test_signal.test_sigwaitinfo_interrupted() because sigwaitinfo() doesn't
raise InterruptedError anymore if it is interrupted by a signal not in its
sigset parameter.

79d68f929d Issue #23646: If time.sleep() is interrupted by a signal, the sleep is now 
retried with the recomputed delay, except if the signal handler raises an
exception (PEP 475).

Modify also test_signal to use a monotonic clock instead of the system clock.

56e8c29a4e Issue #22018: Add _testcapi.raise_signal() 
- Use _testcapi.raise_signal() in test_signal
- close also os.pipe() file descriptors in some test_signal tests where they
  were not closed properly
- Remove faulthandler._sigill() and faulthandler._sigbus(): reuse
  _testcapi.raise_signal() in test_faulthandler
