    Allow forcing the creation or renaming of references
    
    Add internal reference create and rename functions which take a force
    parameter, telling them to overwrite an existing reference if it
    exists.
    
    These functions try to update the reference if it's of the same type
    as the one it's going to be replaced by. Otherwise the old reference
    becomes invalid.
