dix: add helper functions to create DDX touch recs
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.
