Well, all that really adds is safe checking of size... the structs are the same and they use static sizes.  I suppose it's better to go ahead and change that though in case they are ever switched to use arbitrary length strings instead of predefined character arrays.

I get that it compiles to the same thing because it's a macro... but this construct:

AST_LIST_NEXT(new_menu_action, action) = NULL;

seems a little iffy to me.  It's visually like setting the value of a function return.

This is probably for the best for a couple reasons though. For instance, the CONFBRIDGE function can modify the contents of the datastore allocated menu while the user is still in the conference if it is set via AMI. We probably don't want the menu to be modified in place during this time (even if it would be cool to be able to edit a menu while the conference is in progress).
