/**
* Submodules
* ----------
*
* If you want to iterate the refs of a submodule you first need to add the
* submodules object database. You can do this by a code-snippet like
* this:
*
* const char *path = "path/to/submodule"
* if (add_submodule_odb(path))
* die("Error submodule '%s' not populated.", path);
*
* `add_submodule_odb()` will return zero on success. If you
* do not do this you will get an error for each ref that it does not point
* to a valid object.
*
* Note: As a side-effect of this you cannot safely assume that all
* objects you lookup are available in superproject. All submodule objects
* will be available the same way as the superprojects objects.
*
* Example:
* --------
*
* ----
* static int handle_remote_ref(const char *refname,
* const unsigned char *sha1, int flags, void *cb_data)
* {
* struct strbuf *output = cb_data;
* strbuf_addf(output, "%s\n", refname);
* return 0;
* }
*
