Some small fixes (IndexedEntity, IDevice, tunnelEnabled)

BSC-2116

BSC-2116

Change OFPacketIn.MINIMUM_LENGTH from an int to a short. OFPacketIn.setTotalLength() expects a short.

DeviceManager: handle null entity classes returned by classifyEntity (https://github.com/floodlight/floodlight/pull/205)

Fix Device Manager entity handling code [BSC-2046] (https://github.com/floodlight/floodlight/pull/204)

During flow reconciliation, device manager should not call learnDeviceByEntity, which would incorrectly update timestamps of entities existing in flow cache. It should call findDeviceByEntity instead.

Opcodes for RARP in ARP.java (https://github.com/floodlight/floodlight/pull/203)

generated java file (we do a regex replace.)

Also retab'ed build.xml file

IPv4.java - Add static method for IPv4 from int to byte[]. (https://github.com/floodlight/floodlight/pull/201)

DeviceManager and entity classification updates/fixes

If we cannot find an entity in the primary index we need to
classify it into an IEntityClass and the search in the class index.

* Fixed couple of bugs in Device.getIPv4Addresses().
* Add more debugging output to DeviceManagerImpl

updated CLI (https://github.com/floodlight/floodlight/pull/199)

* implement findDestDeviveByEntity()
* findDevice() and findDestDevice() will now throw an exception of the
  supplied fields are not sufficient for the lookup
* test and comment polishing
* reorganizing testing code

[BSC-1838]

Make getLinkType() in LinkDiscoveryManager public. (https://github.com/floodlight/floodlight/pull/198)

Re-add getLinkType() into LinkDiscoveryManager. (https://github.com/floodlight/floodlight/pull/197)

making it possible to get LinkType information both from LinkInfo.getLin... (https://github.com/floodlight/floodlight/pull/196)

The Web UI now has icons and stuff (https://github.com/floodlight/floodlight/pull/195)

(These icons were designed from scratch by me with ASL 2.0 license.)
Nodes are now labeled with their name (DPID or IP+MAC).
Added a hack to ignore multiple attachment points for hosts, since
Floodlight's concept of attachment points doesn't correspond to the
physical topology.

Fix a NPE in injectOFMessage
