Carlos Garnacho 55cc9f3339 gdk: Add _gdk_x11_event_translator_get_window()
This method can be implemented by event translators so they
return the right window from XGenericEventCookie events, as
ev->xany.window isn't meaningful for these.

GdkEventSource now also uses this to find out the right window
filters to apply.
