expand_stack intrinsic takes thread

Browse source 
* libguile/intrinsics.h (scm_t_thread_sp_intrinsic): Change to take
  thread instead of vp.
  (SCM_FOR_ALL_VM_INTRINSICS): Change expand_stack to expect thread, not
  vp.
* libguile/vm-engine.c (ALLOC_FRAME): Call expand_stack with thread.
* libguile/vm.c (thread_expand_stack, scm_bootstrap_vm): Adapt.
