RFC: Routing and Priority lists

Hi,

I apologize for the slow reaction.

Voice guided navigation should never be routed to the earpiece (the
built-in mono speaker) because if you would listen you would not able
to see the map. However, during a phone call navigation instructions
might follow the normal audio targets for the call and be routed to the
earpiece. In addition the incoming call should not ring just beep, but
that is not a routing issue.

So either we would need to dynamically change the priority list or use
multiple priority lists. From Colin comments I understood so that the
multiple lists are preferred. So the priority lists might stay 'static' but
some policy module need to maintain a property on the navigation
stream that tells the 'mode' (ie. in call or not).

That's fine if we do not run to the trouble that some of those path's are
considered as duplicate and filtered out.
