Export TouchEventRejected as TouchRejected 

This function is mostly correct for early reject usage. With a small
change to pass the client resource explicitly and making the
TouchOwnership event optional, it is usable for all rejection scenarios.
This change exports it for use outside Xi/exevents.c and modifies the
name accordingly.
