better unbound variable errors in the vm

Browse source 
* libguile/vm-i-system.c (variable-ref, toplevel-ref)
  (long-toplevel-ref): Fixup callers.

* libguile/vm-engine.c (vm_error_unbound): Don't use vm-error for
  unbound vars, use misc-error. Don't include VM: in the string. Take
  the name directly in finish_args, not as a list.
