This function combines g_menu_attribute_iter_next() with
g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value().
First the iterator is advanced to the next (possibly first) attribute.
If that fails, then %FALSE is returned and there are no other
effects.
If successful, @name and @value are set to the name and value of the
attribute that has just been advanced to. At this point,
g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value() will
return the same values again.
The value returned in @name remains valid for as long as the iterator
remains at the current position. The value returned in @value must
be unreffed using g_variant_unref() when it is no longer in use.
