  Allow vchans to have their own volume control.

  This means you can use two processes producing audio and change their volume
  independently (if they implement mixer controls themselves).
I know this is kind of a hack, but so useful :)  Plus this is since two years in my tree and just has to get out.

We should think if we can switch our locking to use lockmgr locks, because uaudio is taking some code paths which block and thus panic when using spinlocks.
