session: generalize handling of network transports
- compute session type out of transport and network protos - make session, session lookup and session queue code network protocol agnostic This does not update the session layer to support non-ip network layer protocols Change-Id: Ifc2f92845e158b649d59462eb7d51c12af536691 Signed-off-by: Florin Coras <fcoras@cisco.com>
