Since 27e1e22 (prune: factor out loose-object directory
traversal, 2014-10-15), we now have a generic callback
system for iterating over the loose object directories. This
is used by prune, count-objects, etc.
We did not convert git-fsck at the time because it
implemented an inode-sorting scheme that was not part of the
generic code. Now that the inode-sorting code is gone, we
can reuse the generic code. The result is shorter,
hopefully more readable, and drops some unchecked sprintf
calls.
