Fix bug in ActionUtils. OF1.0 transport ports were being parsed as shorts. For ports above 32767, this is bad.

Fixed action serializer for actions that do not have values e.g. strip_vlan and such. Added in a 'n/a' value for the JSON key's value. Perhaps we should rethink how a list of actions is serialized to avoid the 'n/a' all together.

Let's try this again. Fixed the two SFP bugs (Maxence's bug and another that prevented adding drop flows with null or empty-string actions). Also, replaced netty with a newer version in preparation for SSL support.

Revert "Fixed a couple bugs in SFP. (1) Always check the switch we're pushing a new flow to to see if an old flow needs to be removed from another switch (Maxence's bug). (2) Check for empty string in action lists and only print/add actions if they are specified. This allows an empty string or null to mean 'drop.'"

This reverts commit e2458ef3.

Just kidding. Went ahead and added a general try-catch in for actions and matches. In the next minor release, these messages will be returned as errors via the REST API so that partial flows cannot be inserted (based on the correct portions of the JSON-defined flow) and so that the log will not need to be inspected to find the root cause.

Removed all deprecated FlowReconcileManager stuff from unit tests, which is just now showing up as a warning... Also clarified debug message in ActionUtils for actions that do not take the form 'key=value' e.g. 'pop_vlan'. It was phrased as if the action was bad, but it's okay for some that do not take a value.

IPv6 support updated

Support for IPv6

Tweaked SFP syntax (changed my mind about dl and nw as opposed to eth and ipv4). Added acceptance of hex and decimal input for values. Added previously unimplemented matches/actions in loxi to the SFP. Removed all the FlowReconcileManager stuff from DeviceManagerImpl.

Fixed SFP REST API. Forgot to add new flow's DPID to entry2dpid map, thus flow removal never triggered a flow-del message to the switch. Also, added a serializer for OFFlowMod and for OFFlowModMap. The latter is for the double-map of switch-dpid --> map of flow-name --> OFFlowMod object. The former has been separated, since it a JSON serializer for OFFlowMod might come in handy in the future. A present limitation is that the JSON serializer does not use the same syntax as is used to insert a flow-mod via the SFP REST API. This might be confusing for people if they get different output than what they put in. It's a lot less work to implement the serializer as-is though. The next step will be to match the SFP syntax on a per-field basis in the OFFlowModSerializer class.

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.

Static Flow Pusher supports all OF1.3 matches and most OF1.3 actions (with the exception of masks). LoadBalancer corrected; OFFlowAdd used instead of OFFlowModify and OFPort.ZERO correct to OFPort.ANY. ActionUtils, MatchUtils, and InstructionUtils added to support static flow pusher. Strings defining flow fields *standardized* for Floodlight in the new utils classes. This means the REST API for the SFP will expect a sligthly different syntax than the current REST API (for master and 0.90). We can change the field names easily though in the utils files. These names are also referenced for the keys the SFP uses to store flow match fields and actions, just to be consistent.

Fixed build.xml. Fixed/implemented workaround for remaining debug counter compile errors to allow compilation with ant. Static Flow Pusher now matches on all OF1.3 match fields; all OF1.3 actions/set-field are in progress now, but basic out-port action works.
