My initial gut feeling is that this should be adapter based, though that
might be partly fueled by the fact that that's also how the current
pairing and authorization agent is designed. However, I do remember us
discussing this earlier and the outcome back then was (at least based on
your API suggestion) to have a per-device agent. I can't remember the
exact supporting arguments for this, but at least the API does get
simpler since then we don't need a new interface for both adapter and
device objects and the parameter lists of the HandsfreeAgent interface
methods become shorter since we don't need to have the remote device
object path there.
