I started on top of nd/multiple-work-trees but it conflicts badly with
rs/ref-transaction-0 because this is basically code move. So I think
we should make it a separate topic instead, based on latest 'master'.
Junio, you still hit conflicts when merging this with nd/multiple-work-trees,
but that's simpler to resolve (git_snpath -> strbuf_git_path). I
promise to replace the "ref:" code in checkout.c later when both
topics graduate.

So.. first cut. The end result looks nice.

Nguyễn Thái Ngọc Duy (4):
  strbuf.c: keep errno in strbuf_read_file()
  refs.c: refactor resolve_ref_unsafe() to use strbuf internally
  refs.c: move ref parsing code out of resolve_ref()
  refs.c: rewrite resolve_gitlink_ref() to use parse_ref()
