The new package sorted/kvtest provides a generic KeyValue test for all
implementations. Memory, SQLite, and kvfile now use it.
This speeds up the index slurping start-up of my personal Camlistore
server from 30 seconds (when it was doing 17,000+ queries in small
windows) to now just 5 seconds. That 5 seconds can be improved yet
further.
