- disable pads when going to PAUSED, we want to make sure no data is passing when an element is not PLAYING.

Browse source 
Original commit message from CVS:
- disable pads when going to PAUSED, we want to make sure no data is
passing when an element is not PLAYING.
- changed the clock sync API, element should now get a ClockID first and
sync on that. This makes it possible to cancel clock requests.
