Updates to DeviceManagerImplTest to take into account attachment point computation changes due to topology last updated time.

Updates to DeviceManagerImplTest corresponding to changes in attachment point computation using topology last changed time.

Topology module provides last update time.  Device manager ignores entities whose last seen are earlier than the topology update time.

Small cleanups.

Remove useless extra logging of stack trace and Don't try to clean out old ports in case they're not really in storage (https://github.com/floodlight/floodlight/pull/163)

Send LLDPs for all the switches first; then followed by BDDPs. (https://github.com/floodlight/floodlight/pull/162)

When sending LLDPs and BDDPs from all the switches, send LLDPs first and then BDDPs. This would enable direct links to be detected first and reduced instability.

Register everything as an HA role listener where it was missing (https://github.com/floodlight/floodlight/pull/155)

VirtualNetworkFilter now allows any DHCP traffic. (https://github.com/floodlight/floodlight/pull/161)

Fix build issues caused by the introduction of PacketFactory. Now the net.floodlightcontroller.core.test.* files will not try to be run as jUnit tests.

Document the new ITopologyService method (https://github.com/floodlight/floodlight/pull/158)

Read port data from storage when switching to master state (https://github.com/floodlight/floodlight/pull/159)

Change app ID for VirtualNetworkFilter. (https://github.com/floodlight/floodlight/pull/157)

get link notification from topology instead of linkDiscovery. (https://github.com/floodlight/floodlight/pull/156)

topology keeps a list of applied link updates. topologyAware modules can query updated links after getting topologyChanged event

add FlowReconcileService to DeviceManager's dependency list (https://github.com/floodlight/floodlight/pull/153)

Added method to get blocked ports as part of ITopologyService.

Fix warning (https://github.com/floodlight/floodlight/pull/151)

Minor adjustment to link discovery and add switch broadcast cache to ForwardingBase (https://github.com/floodlight/floodlight/pull/150)

Add a flow reconciliation pipeline (https://github.com/floodlight/floodlight/pull/149)

Update to attachment point flapping logic.

Update to attachment point flapping logic.  Use active time instead of last seen to order the entities.  Corresponding changes to unit tests.
