[PATCHv3 0/2] Port `git submodule init` from shell to C

[Stefan Beller <sbeller@xxxxxxxxxx>]

This applies on top of sb/submodule-parallel-update, replacing
sb/submodule-init.

Fixes:

 * a more faithful conversion by staying on stdout (We switch to stderr later
   in another series)
 * use the existing find_last_dir_sep instead of reinventing the wheel.

Stefan Beller (2):
  submodule: port resolve_relative_url from shell to C
  submodule: port init from shell to C
