Robustify frozen file format.

placeholder if builtin is not found, rather than warning.
* src/m4.h (m4_placeholder): New prototype.
* src/builtin.c: Unify error message style.
(m4_placeholder): New function, warn if invoked.
(builtin_tab): Add m4_placeholder.
(m4_defn): Warn if placeholder is encountered.
(find_builtin_by_addr): Handle placeholder.
(find_builtin_by_name): Return placeholder on failure.
(m4_builtin): Treat placeholder as undefined.
* doc/m4.texinfo (Frozen files): Document changes in V and F.
* NEWS: Document this change.
