This commit adds functionality to include the space used in the trash
directory when calculating available space on the node.
It also includes this trash value in the space used cache, with methods
to keep the cache up-to-date as files are trashed, restored, and
emptied.
As part of the commit, the RestoreTrash and EmptyTrash methods have
slightly changed signatures. RestoreTrash now also returns the keys that
were restored, while EmptyTrash also returns the total disk space
recovered. Each of these changes makes it possible to keep the cache
up-to-date and know how much space is being used/recovered.
Also changed is the signature of PieceStoreAccess.ContentSize method.
Previously this method returns only the content size of the blob,
removing the size of any header data. This method has been renamed
`Size` and returns both the full disk size and content size of the blob.
This allows us to only stat the file once, and in some instances (i.e.
cache) knowing the full file size is useful.
Note: This commit simply adds the trash size data to the piece size data
we were already collecting. The piece size data is not accurate for all
use-cases (e.g. because it does not contain piece header data); however,
this commit does not fix that problem. Now that the ContentSize (Size)
method returns the full size of the file, it should be easier to fix
this problem in a future commit.

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.
* Added a gc package at satellite/gc, which contains the gc.Service, which runs garbage collection integrated with the metainfoloop, and the gc PieceTracker, which implements the metainfo loop Observer interface and stores all of the filters (about which pieces are good) for each node.
* Added a gc config located at satellite/gc/service.go (loop disabled by default in release)
* Creates bloom filters with pieces to be retained inside the metainfo loop
* Sends RetainRequests (or filters with good piece ids) to all storage nodes.
* 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
* Add in-memory cache for bandwidth and space usage monitoring
* moved some structs around and added error handling for get piece size query
* added to existing bandwidth test. fixed typo
* added test, updates from PR review, added monkit for new methods
* PR review updates. renamed space used methods
* changed bw cache so that only Add updates the cache and it only overwrites when the date moves forward
* moved bandwidth usage to bw and space usage to pieceinfodb
* fixed interface comment
* removed pointer from sync.Once
* remove infodb locks and give a unique name for each in memory created.
* changed max idle and open to 1 for memory DBs. fixes table locking errors
* fixed race condition
* added file based infodb test
* added busy timeout parameter to the file based infodb for testing
* fixed imports
* removed db.locked() after merge from master
