Xi: update the core listener state if we delivered the touch event

Browse source 
If a TouchBegin is sent to a core client, that client is now the owner.

By the time the TouchEnd is being processed, the client cannot replay
anymore, so we can assume that this is the final touch end and we can clean
up the touch record.

Note: DeliverTouchEmulatedEvent is called for all listeners and immediately
bails out if the client is not the owner and thus shouldn't yet get the
event. Thus, check the return code.
