Peter Hutterer 5d0260cc98 dix: add helper functions for adding/removing touch listeners ...

The DIX will call TouchSetupListeners once for a new touch. After that
the listener list remains static, with listeners only dropping out when they
either reject the grab or disappear.

Exception: if grabs activate they are prefixed to the listeners.
