- reentrant lock was not being used correctly
- fixHashGroup in group handler was not updating global store correctly
- linkUp was not being noted in seenLinks if configuration came after switches connected
- serialization error in global objective store due to missing kryo for Sets
- damaged routepath computation was not taking pair-devs into account
- switch failures were leading to improper ecmpSpg graph updates, and missed hash-group changes
- implemented more next-objective verification as group sub-system can go out-of-sync with objective-store

Two things:
- In dual (paired) ToR scenarios it is possible to have the same outport
in multiple buckets in a hash group, as long as they have different labels.
When adding buckets this was taken into account. But when removing buckets,
only outport was being checked. This bug fix ensures that labels are checked
as well when removing buckets.
- In dual ToR scenarios, getting the right set of hash buckets proved difficult
with existing 'retryHash' mechanism. Repealed and replaced with a bucket corrector
mechanism that periodically corrects the hash group buckets when the topology
has been stable for the last 10 secs. Required the introduction of a VERIFY
operation in Next Objectives. Also added a cli command to trigger this
operation manually.

Also include following refactoring
- Refactor the way we generate ARP probe
- Remove some unused code
Change-Id: I96b1c47bd5731b7b38ef4d19a941d231b5d0054c
In addition,
- Block ARP/NDP on pair port from being sent to controller
- Block DAD on pair port from flooded back to the originated host
- Minor refactoring

Introduces the concept of edge-pairs (or paired-ToRs) which
can have some subnets/prefixes reachable by both ToRs.
- Each ToR can also have prefixes reachable only by itself,
even though it is part of an edge-pair.
- The paired link between ToRs in an edge-pair is ignored
for ECMP calculations.
- Required a change in how destinations and next-hops are stored.
The neighborSet is now a destinationSet, and no longer carries
next-hop info, which is now stored in NextNeighbors. As a result,
the DestinationSetNextObjectiveStoreKey and ECMP group id do not
change as next-hops come and go.
- It is now possible to have buckets in hash groups with the same
outport but different labels.
- DefaultRoutingHandler has been rearraged to be more readable, and
clearly highlight the three major ways that routing changes can
happen in the network.
Also fixes the case where config is added after switches connect to the controller.

- DHCP relay doesn't set destination MAC properly when forwarding the reply
- SR doesn't properly turn off the arp handler in dhcp relay
Change-Id: I7f7660bfe70fee14abcfdd3abb750e4a88b6ec42
- to better align with current BUCK behaviour which only includes java sources
- and few other pom fixes
