character for most keys, and an integer for special keys, instead of always
returning an integer. So it is now possible to distinguish special keys like
keypad keys.

Fix issue 13370: Ensure that ctypes works on Mac OS X when Python is compiled using the clang compiler

fromlist of __import__ propagate.

The problem previously was that if something listed in fromlist didn't
exist then that's okay. The fix for that was too broad in terms of
catching ImportError.

The trick with the solution to this issue is that the proper
refactoring of import thanks to importlib doesn't allow for a way to
distinguish (portably) between an ImportError because finders couldn't
find a loader, or a loader raised the exception. In Python 3.4 the
hope is to introduce a new exception (e.g. ModuleNotFound) to make it
clean to differentiate why ImportError was raised.
