Cygwin/X: Internal WM workaround for Java AWT bug

Browse Source 
Java applications using AWT on JRE 1.6.0 break with non-reparenting WMs AWT
doesn't explicitly know about (See sun bug #6434227)

XDecoratedPeer.handleConfigureNotifyEvent() only processes non-synthetic
ConfigureNotify events to update window location if it's identified the
WM as a non-reparenting WM it knows about (compiz or lookingglass)

Rather than tell all sorts of lies to get XWM to recognize us as one of
those, simply send a synthetic ConfigureNotify for every non-synthetic one
