39f18b30b6 src/backup/data_blob.rs: new load_from_reader(), which verifies the CRC 
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())

c687da9e8e datastore: chown base dir on creation 
When creating a new datastore the basedir is only owned by the backup
user if it did not exist beforehand (create_path chowns only if it
creates the directory), and returns false if it did not create the
directory).

This improves the experience when adding a new datastore on a fresh
disk or existing directory (not owned by backup) - backups/pulls can
be run instead of terminating with EPERM.

Tested on my local testinstall with a new disk, and a existing directory:

a3f3e91da2 backup/chunk_store: rework chunk iterator 
We can now use iter::from_fn() which makes for a much nicer
logic. The only thing better is going to be when we can use
generators with `yield`.

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.

c7f481b642 backup: replace ChunkIterator 
Instead we just build the iterator using our
tools::fs::read_subdir iterator as follows:
Use the index range (0..0x10000) as an iterator, map() it
to yield a subdirectory iterator for each index, then
flatten it.
