[Telepathy] Handle Uniqueness

[Daniel d'Andrada Tenório de Carvalho]

Hi,

The spec (.13) currently doesn't make any statement about its handle 
uniqueness. It's not clear whether, within a connection, a handle alone 
identifies a resource uniquely or if only a tuple (handle_type, handle) 
does that.

By the methods' signatures the second option seens to be the case, but I 
think that having handle uniqueness (instead of per type) would make the 
spec more elegant (as a handle alone would have a unique ID status, 
which is a widespread concept) and you would also discard the 
handle_type parameter from HoldHandles, InspectHandles and ReleaseHandles.

Anyway, regardless of what option is finally chosen, the uniqueness 
concept adopted must be clearly stated in the spec.
