[PATCH damageproto] Add XDamageSubtractAndTrigger operation

XDamageSubtractAndTrigger behaves exactly like
XDamageSubtract except it receives an optional
fence sync object. If the value of this object
is not None, it is triggered by X once all the
rendering associated with the damage regions
being subtracted has completed.
