* new index and structure in db_store * syncronisation: iterator more efficient * syncer history sync is simplified * swarm/api: fix tests NOTE: this represents an interim fix until network layer rewrite is complete Update cleandb.go Just a comment, not to forget fixing this. Update dbstore.go Added a TODO comment to refactor the database constructor. swarm/storage: Adding bucketed chunk counters to chunk database cmd/swarm: cleandb now takes proper PO function based on bzzaccount swarm/storage: fix bucketcount stats in dbstore swarm/storage, cmd/swarm: add db dump as command
