Remove rootfs service in place of snapshot service. Adds
diff service for extracting and creating diffs. Diff
creation is not yet implemented. This service allows
pulling or creating images without needing root access to
mount. Additionally in the future this will allow containerd
to ensure extractions happen safely in a chroot if needed.

No need to have a util package under a package... er, package.
We should move most of this functionality to continuity.

btrfs build tag to turn off building the btrfs snapshot support.

Rollback was not being called when the function was called with
a key which does not exist. This failure to call rollback kept
the database open and caused all new requests to block.

The split between provider and ingester was a long standing division
reflecting the client-side use cases. For the most part, we were
differentiating these for the algorithms that operate them, but it made
instantation and use of the types challenging. On the server-side, this
distinction is generally less important. This change unifies these types
and in the process we get a few benefits.
The first is that we now completely access the content store over GRPC.
This was the initial intent and we have now satisfied this goal
completely. There are a few issues around listing content and getting
status, but we resolve these with simple streaming and regexp filters.
More can probably be done to polish this but the result is clean.
Several other content-oriented methods were polished in the process of
unification. We have now properly seperated out the `Abort` method to
cancel ongoing or stalled ingest processes. We have also replaced the
`Active` method with a single status method.
The transition went extremely smoothly. Once the clients were updated to
use the new methods, every thing worked as expected on the first
compile.
