    1. We now allow lans to be implemented by a path. We did not allow this
       before, cause some of the sanity checking code was a pain to
       implement for lans. Well, no more sanity checking, the user is
       responsible for doing things correctly (after all, they are doing
       experiments with their own switches!).
    
    2. We now allow topologies with more then one switch to be wired
       together. The wires between switches are marked as "trunk" wires,
       which informs the configuration generation code in libosload_switch
       to create the trunks and do the little tagged/untagged magic that is
       required on procurve switches. The same information is used to mark
       the the logical wires between switches as trunks.
    
       Aside: this stuff needs some work; we have spanning tree on by
       default, which causes the trunks to not work correctly. When I turn
       that off, things start working. So need some help from others who now
       about spanning tree stuff.
    
    3. Serious kludging in the Interface and Port libraries related to
       choice of primary keys in the wires table. In order to insert a
       logical wire (or interface) that represents a connection setup by the
       apcon, we have to overload the primary key since the node_id1 side of
       the logical wires is the same as the physical wire to the apcon. We
       have to have overload the node_id2 side too, but that is really just
       a problem when wiring two switches together. Anyway, the kludge just
       maps card1 to a different id, and the Port library unmaps it. It will
       do for now, but really need logical wires to be done better then
       this.
