dix: Each device needs to differ between a core grab and an XI grab,

Browse Source 
otherwise a Xi grab may overwrite or release a core grab.
        Replace grab and associates with coreGrab and deviceGrab structures,
        adjust rest of dix/Xi/etc to compile.

xfree86: Don't check for core devices, we'll have the virtual ones anyway.
         If we check, the first mouse device is duplicated and sends
         double events.
