Update loose_objects_cache when udpating the loose objects map. This
oidtree is used to discover which oids are possibilities when
resolving short names, and it can support a mixture of sha1
and sha256 oids.
With this any oid recorded objects/loose-objects-idx is usable
for resolving an oid to an object.
To make this maintainable a helper insert_loose_map is factored
out of load_one_loose_object_map and repo_add_loose_object_map,
and then modified to also update the loose_objects_cache.

As part of the transition plan, we'd like to add a file in the .git
directory that maps loose objects between SHA-1 and SHA-256. Let's
implement the specification in the transition plan and store this data
on a per-repository basis in struct repository.
