This is v2 of a patch series to implement iteration over references
via iterators. Thanks to Ramsay, Eric, Junio, and David for their
feedback about v1 [1]. I think I have addressed all of the points that
were raised.
Changes from v1 -> v2:
* In "refs: introduce an iterator interface":
* Fix some comments.
* Remove a redundant call to `sort_ref_dir()`.
* Rename the parameters to `overlay_ref_iterator` from `iter0` and
`iter1` to `front` and `back`, and reverse their order.
* Add a comment explaining why merge_ref_iterator_begin() can't do
an is_empty_ref_iterator() optimization.
* In "dir_iterator: new API for iterating over a directory tree":
* Fix some comments.
* Add a warning if `lstat()` fails for a reason other than `ENOENT`.
This patch series applies on top of mh/split-under-lock. It can also
be obtained from my GitHub repo [2] as branch "ref-iterators".
