PyArg_Parse instead of PyArg_ParseTuple if possible.

(empty) definition of the methoddef macro: it's only generated once, even
if Argument Clinic processes the same symbol multiple times, and it's emitted
at the end of all processing rather than immediately after the first use.

@unittest.skipUnless(ssl, '...') doesn't work because the class body uses the
nntplib.NNTP_SSL attribute which doesn't exist.

* Rename check_socket_and_wait_for_timeout() to PySSL_select()
* PySSL_select() is now clearly splitted betwen poll() and select()
* Add empty lines for readability

* Use the new _PyTime_FromSeconds() function to set the timeout to -1 second
  for socket.settimeout(None). It avoids a special case in internal_select()
  because of a rounding issue: -1 nanosecond is rounded to 0 millisecond which
  means non-blocking, instead of blocking.
* Check if the interval the negative in sock_call_ex() instead of doing the
  check in internal_select(). sock_call_ex() remembers if the socket has a
  timeout or not, which avoids a race condition if the timeout is modified in a
  different thread.

Fix also _Py_InitializeEx_Private(): initialize time before initializing
import, import_init() uses the _PyTime API (for thread locks).

store the result of sendto() instead of the C int type.

(The bug was already fixed in the default branch, but differently.)

result of sendto() instead of the C int type.

See the PEP 475 for the rationale.

sock_call_ex() gets the socket error code when the socket function fails.
sock_connect_impl() didn't set the error correctly.
