Ignore deprecated LIBINPUT_EVENT_POINTER_AXIS events and handle LIBINPUT_EVENT_POINTER_SCROLL_WHEEL, LIBINPUT_EVENT_POINTER_SCROLL_FINGER and LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS instead. The scroll source is now encoded in the event type making libinput_event_pointer_get_axis_source and translate_scroll_source redundant.
