    This patch is a v4l2 update.  Changes:
    
    * added new ioctls (VIDIOC_G_PRIORITY, VIDIOC_S_PRIORITY) to give v4l apps
      priorities for tuning and other controls.  Main purpose is that backgrounds
      applictions like nxtvepg which are fishing informations from /dev/vbi
      (teletext, epg, ...) can run at lower priority than interactive tv apps and
      thus the user isn't annonyed with unexpected channel switches.
    
    * add a set of helper functions to handle priorities to the v4l2-common
      module.
    
    * minor fixes in the v4l1-compat module.
    
    * minor header file fixes.
