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 = ?>>)

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).

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.
