session: rules tables
This introduces 5-tuple lookup tables that may be used to implement custom session layer actions at connection establishment time (session layer perspective). The rules table build mask-match-action lookup trees that for a given 5-tuple key return the action for the first longest match. If rules overlap, ordering is established by tuple longest match with the following descending priority: remote ip, local ip, remote port, local port. At this time, the only match action supported is to forward packets to the application identified by the action.
