Fixed some more unit tests. In the process, discovered some errors in more overridden equals(). Also, discovered I had inadvertently commented out an important few lines the routing module uses to set the ingress port of flows used in the route. Those lines are now ported and use MatchUtils to copy the Match properly.

Fixed lots of compile errors in unit tests; mostly involved replacing longs with DatapathIds, byte[]s with MacAddresses and Ipv4Addresses, and shorts with OFPorts and VlanVids; some refactoring of flow mod contruction was also done to align with loxi's builders. The static flow puser now supports IP TOS for OF1.0 and for OF1.1+ it supports match/rewrite to either ECN or DSCP bits.

This reverts commit 4ae94669.

Refactored structure of core components to work with openflowj-loxi.
Presently refactoring Routing, Firewall, Forwarding, DeviceManager,
LinkDiscovery, Topology, and LearningSwitch.
Hub has been refactored.

bootstrap a cluster without needing to use SyncClient manually
2) Configure sync service to use authenticated connections by default
3) Set up VM with a default set of authentication credentials which
at the moment are simply generated a VM build time.
4) Some improvements to cleanup of netty to avoid leaving around
non-daemon timer threads that prevent clean shutdown.

Add support for autobootstrapping a cluster without relying on manul configuration or configuration in cassandra

Support for the role request/reply vendor extensions used in OVS.
