Deprecate the pieceinfo database, and start storing piece info as a header to
piece files. Institute a "storage format version" concept allowing us to handle
pieces stored under multiple different types of storage. Add a piece_expirations
table which will still be used to track expiration times, so we can query it, but
which should be much smaller than the pieceinfo database would be for the
same number of pieces. (Only pieces with expiration times need to be stored in piece_expirations, and we don't need to store large byte blobs like the serialized
order limit, etc.) Use specialized names for accessing any functionality related
only to dealing with V0 pieces (e.g., `store.V0PieceInfo()`). Move SpaceUsed-
type functionality under the purview of the piece store. Add some generic
interfaces for traversing all blobs or all pieces. Add lots of tests.
checker_segment_total_count - Number of total segments in pointer during checker iteration
checker_segment_healthy_count - Number of healthy segments in pointer during checker iterationn
time_since_checker_queue - Seconds elapsed between checker queue and beginning repair
time_for_repair - Seconds elapsed between beginning repair and ending repair/dequeueing
