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 = ?>>)

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.

Instead we just build the iterator using our

Use the index range (0..0x10000) as an iterator, map() it
to yield a subdirectory iterator for each index, then
flatten it.
