Make mixer support setting the mute attribute at audio driver level, if one exists separately from volume. As of this commit, no libao2 driver exposes such an attribute yet; that will be added in later commits. Since the mute status can now be set externally, it's no longer completely obvious when the player should automatically disable mute when uninitializing an audio output. The implemented behavior is to turn mute off at uninitialization if we turned it on and haven't noticed it turn off (by external means) since.
