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.

All these functions only accept positive timeouts, so this change has no effect
in practice.

Modify devpoll_flush() to use _Py_write() instead of calling directly write().

* _Py_open() now raises exceptions on error. If open() fails, it raises an
  OSError with the filename.
* _Py_open() now releases the GIL while calling open()
* Add _Py_open_noraise() when _Py_open() cannot be used because the GIL is not
  held

Cast from time_t (64 bit) to long (32 bit). It should fix a compiler warning.

It should make test_asyncio more reliable, especially test_timeout_rounding() test.

Improve also debug info to analyze the issue

instead of rounding towards zero. For example, a timeout of one microsecond is
now rounded to one millisecond, instead of being rounded to zero.

The bug was introduced with the select.epoll module! So it's 5 years old :-)

Add also tests on fileno() method and closed attribute of select.epoll and select.kqueue.
