Made tst_QWidget::updateWhileMinimized() pass.

This requires adding a couple of window system interface events, namely
Map, Unmap, and Expose. When a widget is minimized on X11 it is
unmapped, and thus update requests should not be delivered. Instead the
event will delivered when the widget is mapped, which causes an Expose
event to be sent. The Unmap and Expose event thus need to be handled in
QWidgetWindow, and Map is also added for the purpose of API symmetry
(and for future needs).
