Heap frame "stack holders" are raw scm_vm / scm_vm_cont pointers

Browse source 
* libguile/frames.h (struct scm_frame): stack_holder is a void*.
* libguile/frames.c (scm_i_frame_stack_base, scm_i_frame_offset): Expect
  stack_holder to be the raw struct scm_vm or scm_vm_cont.

* libguile/continuations.c (scm_i_continuation_to_frame):
* libguile/stacks.c (scm_make_stack)
* libguile/vm.c (vm_dispatch_hook): Adapt creators.
