Improve --debugmode behavior.
* m4/m4module.h (m4_debug_decode): Simplify interface.
* m4/debug.c (m4_debug_decode): Remove parameter, and handle
setting the new value.
* modules/gnu.c (debugmode): Adjust caller.
* src/freeze.c (reload_frozen_state): Likewise.
* src/main.c (main): Likewise.
(usage): Fix default for --debug.
* doc/m4.texinfo (Debugging options): Add an example.
