Add a new "add-config" subcommand to `git submodule--helper` with the
goal of converting part of the shell code in git-submodule.sh related to
`git submodule add` into C code. This new subcommand sets the
configuration variables of a newly added submodule, by registering the
url in local git config, as well as the submodule name and path in the
.gitmodules file. It also sets 'submodule.<name>.active' to "true" if
the submodule path has not already been covered by any pathspec
specified in 'submodule.active'.
This is meant to be a faithful conversion from shell to C, although we
add comments to areas that could be improved in future patches, after
the conversion has settled.

The v3 mostly looks good to me. Just one style nit:
[ ... ]
+static void configure_added_submodule(struct add_data *add_data)
+{
+ char *key;
+ char *val = NULL;
+ struct child_process add_submod = CHILD_PROCESS_INIT;
+ struct child_process add_gitmodules = CHILD_PROCESS_INIT;
+
+ key = xstrfmt("submodule.%s.url", add_data->sm_name);
+ git_config_set_gently(key, add_data->realrepo);
+ free(key);
+
+ add_submod.git_cmd = 1;
+ strvec_pushl(&add_submod.args, "add",
+ "--no-warn-embedded-repo", NULL);
+ if (add_data->force)
+ strvec_push(&add_submod.args, "--force");
+ strvec_pushl(&add_submod.args, "--", add_data->sm_path, NULL);
+
+ if (run_command(&add_submod))
+ die(_("Failed to add submodule '%s'"), add_data->sm_path);
+
+ if (config_submodule_in_gitmodules(add_data->sm_name, "path", add_data->sm_path) ||
+ config_submodule_in_gitmodules(add_data->sm_name, "url", add_data->repo))
+ die(_("Failed to register submodule '%s'"), add_data->sm_path);
+
+ if (add_data->branch)
+ if (config_submodule_in_gitmodules(add_data->sm_name,
+ "branch", add_data->branch))
+ die(_("Failed to register submodule '%s'"), add_data->sm_path);

As the body of if(add->branch) has a nested if in it and totally spans 3 lines, it might
be a good idea to wrap it in braces like so:
if (add_data->branch) {
if (config_submodule_in_gitmodules(add_data->sm_name,
"branch", add_data->branch))
die(_("Failed to register submodule '%s'"), add_data->sm_path);
}
... or collapse both conditionals into a single if like so:
if (add_data->branch &&
config_submodule_in_gitmodules(add_data->sm_name, "branch", add_data->branch))
die(_("Failed to register submodule '%s'"), add_data->sm_path);
