x11: Partially convert to XCB.

This commit mostly converts the X11 handling to XCB. There are still
some uses of XLib to deal with the X11 session handling modules, however all
client-side code should now be free of XLib and thus this should fix Bug #799

Note that this removes the screen-based changes by Leszek Koltunski
in 65e80, however this will be restored in due course.
