dix: add helper functions to create DDX touch recs

Browse Source 
DDX touch points are the ones that keep records of the driver-submitted
touchpoints. They're unaffected by the grab state and terminate on a
TouchEnd submitted by the driver.

The client ID assigned is server-global.

Since drivers usually submit in the SIGIO handler, we cannot allocate in the
these functions.
