> - Unify CallApi*Stub, for * in Function, Accessor,
>   FunctionWithFixedArgs.
>   (Since these are now all doing the same thing.)
> - Rename the unified stub (and interface descriptors) to
>   *ApiCallback*, since that's really what they're doing.
> - Refuse inlining an API callback if its number of
