IMO we should address this separately, first with absolute volume
control and then add media browsing.

Probably not necessary since the sender + object path should give us a
unique name we can use to identify different players.

No idea why you need this, but I guess this is for media browsing so I
would have in separate.

This is way too big, I guess we can group the passthrough in a single
one since if the player doesn't support some it can just ignore, also
for browsing we might have a different interface since the database
may not be directly handled by the player. Actually I strong believe
browsing would fit better as an OBEX based profile because of the
operations and the relation with a database is very similar to other
OBEX based profiles such as PBAP and MAP, but I guess it is too late
to do something about it.

Im afraid Volume belong to MediaTransport not to MediaPlayer,
otherwise we are just able to change the volume of the addressed
player not the master volume of the headset itself which the playback
can be mixed with different audio source.
