regular chunks are only decoded when their contents are accessed, in
which case we need to have the key anyway and want to verify the digest.
for blobs we need to verify beforehand, since their checksums are always
calculated based on their raw content, and stored in the manifest.
manifests are also stored as blobs, but don't have a digest in the
traditional sense (they might have a signature covering parts of their
contents, but that is verified already when loading the manifest).
this commit does not cover pull/sync code which copies blobs and chunks
as-is without decoding them.

And make verify_crc private for now. We always call load_from_reader() to
verify the CRC.
Also add load_chunk() to datastore.rs (from chunk_store::read_chunk())
The download methods used to take the destination by value
and return them again, since this was required when using
combinators before we had `async fn`.
But this is just an ugly left-over now.

futures-0.3 has a futures::future::abortable() function
which does the exact same, returns an Abortable future with
an AbortHandle providing an abort() method.
