with 128B/sec, a satellite with 10min default timeout could already
closed its connection to a node even though the node was able to
compelete the transfer.

..before they are transferred to another node and submitted to the
satellite as successful piece transfers, because if we submit an invalid
signature, the node will be marked as a cheater and disqualified
immediately.
These signatures should have been validated when the piece was
originally stored, but bitrot does happen and needn't be cause for an
immediate DQ.

Most places now need the NodeURL rather than the ID and Address
separately. This simplifies code in multiple places.

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.

Fixes a data race caused by not waiting for workers to finish
before shutting down. Currently this ended up failing logging
because it was closed when test tried to write to it.

* 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.
* Make the exiting node check piece hashes, piece IDs, and piece hash signatures before relaying successful transfer data to the satellite.
* Enable immediate graceful exit failure for "successful" transfers that fail satellite-side validation.
* Move transfer piece logic in storagenode worker to separate function (to make the worker easier to understand)
