[libgit2-glib] Make the submodule api to build again.

[Ignacio Casal Quinteiro <icq src gnome org>]

commit 4d692c0d8fbd916382196aabaf4682074f8d6663

    Make the submodule api to build again.
    
    See that we still need to add the missing api, update the docs
    and fix the foreach_submodule as it seems inconsistent with
    the rest of the API. I sent a mail to the list asking for
    help on this issue.
