This change updates the storagenode piecestore apis to expose access to
the full piece size stored on disk. Previously we only had access to
(and only kept a cache of) the content size used for all pieces. This
was inaccurate when reporting the amount of disk space used by nodes.
We now have access to the total content size, as well as the total disk
usage, of all pieces. The pieces cache also keeps a cache of the total
piece size along with the content size.

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.
* storagenode: remove datetime calls in favor of UTC
datetime only has second level granularity whereas string
comparisons don't. Since we're wiping everything anyway, it's
easier to just use UTC everywhere rather than migrate to
datetime calls.
* add utcdb to check that arguments are utc
* storagenodedb: add trivial tests to ensure calls work
This at least tests that all of the timestamps passed in are
in the UTC timezone.
* fix truncated comment and change migrations to be UTC
- Drops some unused indexes
- Applies a computed index to timestamp columns
- Applies a partial index for expired pieces
- Uses BETWEEN to avoid some datetime calls
- Filters expired piece search by those that aren't NULL
