Move the heavy lifting in BlockLocator from the syncer to the syncee (#1324)
* Add a new message: BlockLocatorHighestHash.

* Add a new message: IBDBlockLocator.

* Implement HandleIBDBlockLocator.

* Reimplement findHighestSharedBlockHash.

* Make HandleIBDBlockLocator only return hashes that are in the selected parent chain of the target hash.

* Increase the cache sizes of blockRelationStore, reachabilityDataStore, and ghostdagDataStore.

* Fix wrong initial highHash in findHighestSharedBlockHash.

* Make go vet happy.

* Protect against receiving wrong messages when expecting MsgIBDBlockLocatorHighestHash.
