* aout_Volume* functions now do their own vlc_object_find() on the

  audio output. Consequently, the first argument can be any vlc_object_t.
* modules/gui/macosx/*: greatly simplified volume functions ; you can now
  call aout_Volume* even when there is no audio output, and the volume
  will be saved for later use.
