vref, vset members of scm_t_array_handle

Browse source 
* libguile/array-handle.h (scm_t_array_ref, scm_t_array_set): Rename
  from scm_i_t_array_ref, scm_i_t_array_set.
  (scm_t_array_handle): Copy vref and vset from impl to handle.
  (scm_array_handle_ref, scm_array_handle_set):

* libguile/array-map.c (racp, ramap, rafe, rafill, array_index_map_1):
* libguile/array-handle.c (scm_array_get_handle): Adapt.
