Issue #23485: select.select() is now retried automatically with the recomputed

timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.

The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.
