Add wheel_status() function to the ipod "4g" button driver (i.e. all ipods excluding the 3G and 1st gen mini) to read the absolute position the wheel is being touched (0..95 - clockwise from top, or -1 for untouched), plus the wheel_send_events(bool) function to disable/enable sending normal scrolling events - based on patch #4721 from Mikael Magnusson.
