On Android orientation changes are reported from the DisplayListener.onDisplayChanged() method, while the screen size changes are reported from QtLayout.onSizeChanged(). In practice these callbacks come in random order, so rotating the screen multiple times might result in inconsistent order of signals and events. This patch makes sure that size change events always happen before orientation changes. This is done by caching the new orientation values and reporting them only when needed. At this point we also need to use QMetaObject::invokeMethod() for orientation change, like it is done for geometry change. Otherwise the orientation update can still be processed earlier than the geometry change. Also note that at some point we might get an orientation change without a size change (for example Qt::LandscapeOrientation -> Qt::InvertedLandscapeOrientation). That is the reason for isSimilarRotation() helper function. As a drive-by: ignore size changes with inconsistent values when window size is reported to have old orientation, while the screen has already been rotated. In such cases a new size change will be triggered shortly with normal value.
