[PATCH 0/4] Fix bugs related to real_path()

["Alexandr Miloslavskiy via GitGitGadget" <gitgitgadget@gmail.com>]

The issue with `real_path()` seems to be long-standing, where multiple
people solved parts of it over time. I'm adding another part here
after I have discovered a crash related to it.

Even with this step, there are still problems remaining:
* `read_gitfile_gently()` still uses shared buffer.
* `absolute_path()` was not removed.

These issues remain because there're too many code references and I'd like
to avoid submitting a single topic of a scary size.

Alexandr Miloslavskiy (4):
  set_git_dir: fix crash when used with real_path()
  real_path: remove unsafe API
  real_path_if_valid(): remove unsafe API
  get_superproject_working_tree(): return strbuf
