[recipes/wip/clone: 1/2] Add gr_recipe_clone

[Matthias Clasen <matthiasc src gnome org>]

commit ff3ceafcc42b8efbf048e5bc3839789803e08c48
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue May 23 22:43:08 2017 -0400

    Add gr_recipe_clone
    
    This will be used to make copies of existing recipes.
    Still to be determined: Do we want to keep a reference
    to the original?
