+CRUDE HACK ALERT: this patch adds a new device control (DEVICE_RAWEVENT)
+which cannot be exported in the protocol because the xDeviceRaweventCtl
+carries a C pointer to the tslib event hook. For lack of a better idea,
+I added this to get the event hook pointer from Xext/xcalibrate.c into
+tslib.c, where the now-private _raw_event_hook and _raw_event_closure
+pointers are manipulated instead of, like before, in the Xcalibrate
+extension itself.
