Todd Gruben 547ee14f5b all test green on rbf. WOOT.
- rbf had races around the new rootRecords cache in tx
 - rbf tx needed a write lock on the db now that rootRecords are written
 - added a global registry for rbfDB to correctly dedup instances
 - implement DeleteFragment, DeleteIndex for rbf
 - use badger style keys for rbf to allow content checksumming to be list
    containers in the same order
 - lots of other integration of rbf into pilosa layer.
