-Add fence sync objects -Add fence sync devPrivates -Add a X sync module screen private -Add wrappable functions to create and destroy fence sync objects -Give fence sync objects wrappable functions to trigger, test, and reset their 'triggered' value. -Give fence sync objects wrappable functions to notify driver when adding/removing triggers to/ from the sync object.
