callees now check their args, cons rest list, reserve locals

* gdbinit: Ignore SIGPWR and SIGXCPU, which the BDW GC seems to use.

* libguile/vm-engine.h (FETCH_WIDTH): Remove unused macro.
  (INIT_ARGS, INIT_FRAME): Remove; callees now check their args and
  reserve space for their locals.

* libguile/vm-engine.c:
* libguile/vm-i-system.c: Turn on callee arg checking and local
  reservation. Seems to work!
