Add support for an extended style of _NET_WM_SYNC_REQUEST_COUNTER

Browse Source 
If an application provides two values in _NET_WM_SYNC_REQUEST_COUNTER,
use that as a signal that the applications wants an extended behavior
where it can update the counter as well as the window manager. If the
application updates the counter to an odd value, updates of the
window are frozen until the counter is updated again to an even value.
