session: allow transports to generate closed notifications
In contrast to the closing notification, whereby a transport informs
the session layer that is beginning the closing procedure, this allows
transports to notify the session layer of the fact that the transport is
"fully" closed, i.e., it expects no more data.
Also:
- adds app closed state for sessions
- changes tcp to have it notify when an active close has finished
Type: feature
