So far KWindowSystem had a custom implementation to monitor the
compositing selection using XFixes and an own event filter. This
change simplifies it by porting to KSelectionWatcher to share more
code. While the XFixes approach is actually better it's also fighting
with Qt which might result in events getting lost. At least we have
reports about the code being racy at startup.
