[PATCH v3 0/3] Keep .lock file paths absolute

v3 requires rs/strbuf-getcwd, turns paths to absolute from the
beginning, and kills the last use of PATH_MAX in lockfile.c thanks to
strbuf_readlink().

Nguyễn Thái Ngọc Duy (3):
  lockfile.c: remove PATH_MAX limitation (except in resolve_symlink)
  lockfile.c: remove PATH_MAX limit in resolve_symlink()
  lockfile.c: store absolute path
