  git_futils_mkdir_*: make a relative-to-base mkdir
  
  Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter
  assumes that we own everything beneath the base, as if it were
  being called with a base of the repository or working directory,
  and is tailored towards checkout and ensuring that there is no
  bogosity beneath the base that must be cleaned up.
  
  This is (at best) slow and (at worst) unsafe in the larger context
  of a filesystem where we do not own things and cannot do things like
  unlink symlinks that are in our way.
