Typically, when we have repo_* and non-repo_* variants, we use a "static
inline" function, e.g. from refs.h:

  int repo_dwim_ref(struct repository *r, const char *str, int len,
        struct object_id *oid, char **ref, int nonfatal_dangling_mark);

  static inline int dwim_ref(const char *str, int len, struct object_id *oid,
          char **ref, int nonfatal_dangling_mark)
  {
    return repo_dwim_ref(the_repository, str, len, oid, ref,
            nonfatal_dangling_mark);
  }

I think we should do the same here, instead of using "#ifndef
NO_THE_REPOSITORY_COMPATIBILITY_MACROS".

From I can gather from "git log -S
NO_THE_REPOSITORY_COMPATIBILITY_MACROS", that macro was introduced
in e675765235 (diff.c: remove implicit dependency on the_index,
2018-09-21) and all instances of that macro were introduced around that
time. At the time, there was an effort to get rid of the_repository and
the_index almost everywhere (except builtins), and the macro would
ensure that we did this successfully.

We did such a good job with the_index that we flipped the default from
NO_THE_INDEX_COMPATIBILITY_MACROS to USE_THE_INDEX_COMPATIBILITY_MACROS
(f8adbec9fe (cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch,
2019-01-24)) but it looks like we never got there with the_repository.
I couldn't find any instances of "#define
NO_THE_REPOSITORY_COMPATIBILITY_MACROS", so I think we should just use
"static inline" instead.

Alternatively, one could get rid of the non-repo_* variant and adjust
all existing callers to use "struct repository", but that's a lot of
churn and may conflict with other in-flight series, so that's probably
left for another time.
