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.
