For elabinelab, snmpit -t (-r) no longer does an individual trunk
enable/disable on each port (one XMLRPC per). Instead, do this as part of the remotedovlans and remotedestroyvlans. Some reorg in doVlansFromTables() do deal with vlans that need to be trunked in dual mode. That vlan must be created first, the ports trunked, and the rest of the vlans created.
