Moving this to my own branch (I am forking it)

This deletes/add flows from the switch out of forwarding when the firewall rule changes.

Fixed my delete test case by making sure the message written was correct. (This will be expanded upon in the future).

Added test cases for Forwarding if there is a decision packet.

Updated Firewall.java so that addRule and deleteRule and enableFirewall announce that a rule is being changed in the firewall. Then the IRoutingDecisionChangedListener shall alert Forwarding to update the flowtable accordingly.  None of this is tested and the TopologyManager needs to be fixed.  I might even want to move the change out of TopologyManager altogether since RoutingDecisionChange doesn't concern it.

Changes were made to the FirewallTest.java unit test in order to test if the correct descriptor was added to the RoutingDecisions.

TODO:
   * RoutingDecisionsChanged event
      * Define Listener class
      * Add Listener registration/messaging (probably going into IRoutingService)
      * Add code to fire event when firewall rules change.
      * Add code to fire event when firewall enable/disable happens.
      * Add code to handle RoutingDecisionsChanged in Forwarding
   * Unit tests
   * Functional tests

Changed DeviceResource to return a JSON object instead of returning a list.

Many REST ingest schemes (e.g. Graylog "JSON path from HTTP") expect servers to return well-formed JSON objects.  Floodlight is sometimes returning values that lack root objects.

Was:
   [ <list-of-device-objects>]

Now:
   { 'devices' : <list-of-device-objects> }

Add ability to permit all origins when using REST API

Add default of FALSE to allowing all origins in cross-domain requests. Remove old CORS code that was commented out.

Update Web UI to default to /ui/index.html for any request to /ui/. Also add in a filter for allowing any origin.

Update to a new web user interface

Java 8

Update travis-ci to test against oraclejdk8. openjdk8 is not supported yet, apparently (but should still work w/Floodlight).

Updated to Java 8, junit-4.12, easymock-3.4. Still having trouble having unit tests pass in Eclipse for DeviceManagerImplTest, but they work find in maven and ant. testPacketInBasic and testPacketInBasicIPv6 are the trouble makers (fail occasionally).

Improve in_port match and output action handling in Static Flow Pusher

Update MatchUtils and ActionUtils to fully support parsing 32-bit signed and unsigned port numbers in hex and decimal from strings. Also improved and added more keywords for ingress and output ports to support local, table, normal, controller, in_port, all, and flood without care for the openflow version.

Remove Forwarding's stale flows upon port/link failures

Handle link and port down events in Forwarding. Remove flows ingress and egress a failed port or link to eliminate stale entries. This is done in Forwarding instead of the Link Discovery Manager, since some user modules might not want their flows removed and wish for them to persist until the link comes back up.

Do not send LLDP if we're in SLAVE role

Need to check for empty Optional instead of null

Oh, Brocade...

keystore path doesn't matter if we're using vanilla HTTP

Add link speed to statistics module's link utilization tracking
