This adds a thin type that holds the state associated with the leveldb.DB, leaving the huge Instance type more or less stateless. Also moves some keying stuff into the DB package so that other packages need not know the keying specifics. (This does not, yet, fix the cmd/stindex program, in order to keep the diff size down. Hence the keying constants are still exported.)
