[PATCH 03/24] Xi: if we delivered a TouchEnd to a passive grab, end it

[Peter Hutterer]

ef64b5ee97099618cf2e2cbbd3e471095695ae24 (which introduced the
TOUCH_CLIENT_ID check) has a wrong assumption that generated touch events
(TOUCH_CLIENT_ID) should not terminate passive grabs.
This is untrue, a TouchEnd may be generated in response to a TouchReject
higher up. If we _deliver_ an event to a client, terminate the passive grab.

This requires us to count the actually delivered events too (first hunk).
