* 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
This change imports the Swarm protocol codebase. Compared to the 'swarm'
branch, a few mostly cosmetic changes had to be made:
* The various redundant log message prefixes are gone.
* All files now have LGPLv3 license headers.
* Minor code changes were needed to please go vet and make the tests
pass on Windows.
* Further changes were required to adapt to the go-ethereum develop
branch and its new Go APIs.
Some code has not (yet) been brought over:
* swarm/cmd/bzzhash: will reappear as cmd/bzzhash later
* swarm/cmd/bzzup.sh: will be reimplemented in cmd/bzzup
* swarm/cmd/makegenesis: will reappear somehow
* swarm/examples/album: will move to a separate repository
* swarm/examples/filemanager: ditto
* swarm/examples/files: will not be merged
* swarm/test/*: will not be merged
* swarm/services/swear: will reappear as contracts/swear when needed
