Instead of having one touch events representing different types of touch events by providing a touch type, have one separate event type per touch type. This means the LIBINPUT_EVENT_TYPE_TOUCH is replaced with LIBINPUT_EVENT_TYPE_TOUCH_DOWN, LIBINPUT_EVENT_TYPE_TOUCH_MOTION, LIBINPUT_EVENT_TYPE_TOUCH_UP and LIBINPUT_EVENT_TYPE_TOUCH_CANCEL.
