Wolfgang Bumiller 7bc1d72778 add IndexFile trait
We want to be able to iterate through digests of index
files, but without always having to distinguish between
dynamic and fixed types, so add a trait we can use as a
trait object.

Unfortunately the iterator needs to yield copies as
iterators cannot yield values with life times when
represented as trait objects (Box<dyn Iterator<Item = ?>>)

Wolfgang Bumiller fded74d0c7 style: BufferedReader -> BufferedRead
Single-method traits usually use the same name as their
method and aren't usually the 'noun' (which is usually an
implementation of them instead).

Wolfgang Bumiller 9ac6ec868a backup/chunk_store: split insert_chunk
The protocol handler will receive chunk data plus a hash
pre-calculated by the client. It will verify the hash before
sending it up to the datastore in order to respond to the
client with an error on a mismatch, so there's no need to
recalculate the hash another time.
