* 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.
instead of raising InterruptedError if the connection is interrupted by
signals, signal handlers don't raise an exception and the socket is blocking or
has a timeout.
socket.socket.connect() still raise InterruptedError for non-blocking sockets.
The BEGIN_SELECT_LOOP and END_SELECT_LOOP macros of socketmodule.c don't handle
EINTR. Functions using these macros use an inner loop to handle EINTR, but they
don't recompute the timeout.
This changes replaces the two macros with a new sock_call() function which
takes a function as a parameter. sock_call() recomputes the timeout, handle
false positive and handle EINTR.
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.
Call PyErr_CheckSignals() immediatly if connect() or select() fails with EINTR
in internal_connect().
Refactor also the code to limit indentaton and make it more readable.
The function now returns the error code instead of using the global errno
(POSIX) or WSAGetLastError() (Windows).
internal_connect() now returns errno if getsockopt() fails.
Fixed ambigious reverse mappings. Added many new mappings. Import mapping
is no longer applied to modules already mapped with full name mapping.
Added tests for compatible pickling and unpickling and for consistency of
_compat_pickle mappings.

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.
