Some systematic clean-up.

- UNUSED macro that expands to __attribute__((unused)) for gcc
- move rcsid around so that they can be tagged UNUSED.
- activate -Wunused.
- use UNUSED instead of kludgy junk for function arguments.
- add extern to all extern prototypes.
- update comments in lst.h.
- clean up var.c a little bit, constifying arguments, updating comments...
