This is based on Jeff's most excellent work to identify why
non-recursive listing under postgreskv was phenomenally slow. It turns
out PostgreSQL's query planner was actually using two sequential scans
of the pathdata table to do its job. It's unclear for how long that has
been happening, but obviously it won't scale any further.
The main change is propagating bucket association with pathnames through
the CTE so that the query planner lets itself use the pathdata index on
(bucket, fullpath) for the skipping-forward part.
Jeff also had some changes to the range ends to keep NULL from being
used- I believe with the intent of making sure the query planner was
able to use the pathdata index. My tests on postgres 9.6 and 11
indicate that those changes don't make any appreciable difference in
performance or query plan, so I'm going to leave them off for now to
avoid a careful audit of the semantic differences.
There is a test included here, which only serves to check that the new
version of the function is indeed active. To actually ensure that no
sequential scans are being used in the query plan anymore, our tests
would need to be run against a test db with lots of data already loaded
in it, and that isn't feasible for now.

* put TestCreateV0 back in StoreForTest
* avoid direct handles to V0 pieceinfo db
* type mismatch fix
* use storage.Blobs interface in store_test.go
..instead of filestore.Store. this will allow filestore.Store to become
unexported.
* unexport filestore.Store
rename it to blobStore. things should use the storage.Blobs interface
instead. changes in this commit are purely mechanical (made through the
"refactor" tool in Gocode followed by search/replace on the word "Store"
within the storage/filestore/ directory).
* kill filestore.StoreForTest
now that filestore.blobStore is unexported, there isn't a need for a
specialized wrapper type. this (not coincidentally) also makes it
possible for the WriterForFormatVersion() method on
storagenode/pieces.StoreForTest to work, without requiring everything to
wrap the store.blobs attribute in a filestore.StoreForTest, which was
impractical.
We don't use reverse listing in any of our code, outside of tests, and
it is only exposed through libuplink in the
lib/uplink.(*Project).ListBuckets() API. We also don't know of any users
who might have a need for reverse listing through ListBuckets().
Since one of our prospective pointerdb backends can not support
backwards iteration, and because of the above considerations, we are
going to remove the reverse listing feature.

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.
* pkg/datarepair/repairer: Track always time for repair
Make a minor change in the worker function of the repairer, that when
successful, always track the metric time for repair independently if the
time since checker queue metric can be tracked.
* storage/postgreskv: Wrap error in Get func
Wrap the returned error of the Get function as it is done when the
query doesn't return any row.
* satellite/metainfo: Move debug msg to the right place
NewStore function was writing a debug log message when the DB was
connected, however it was always writing it out despite if an error
happened when getting the connection.
* pkg/datarepair/repairer: Wrap error before logging it
Wrap the error returned by process which is executed by the Run method
of the repairer service to add context to the error log message.
* pkg/datarepair/repairer: Make errors more specific in worker
Make the error messages of the "worker" method of the Service more
specific and the logged message for such errors.
* pkg/storage/repair: Improve error reporting Repair
In order of improving the error reporting by the
pkg/storage/repair.Repair method, several errors of this method and
functions/methods which this one relies one have been updated to be
wrapper into their corresponding classes.
* pkg/storage/segments: Track path param of Repair method
Track in monkit the path parameter passed to the Repair method.
* satellite/satellitedb: Wrap Error returned by Delete
Wrap the error returned by repairQueue.Delete method to enhance the
error with a class and stack and the
pkg/storage/segments.Repairer.Repair method get a more contextualized
error from it.
* added scopelint and correcte issues found
