* libguile/array-map.c
- rafill, ramap, rafe, racp: object from SCM_I_ARRAY_V always
has base 0, lbnd 0 and inc 1; make use of this.
* libguile/arrays.c
- array_handle_ref, array_handle_set: idem.
- array_get_handle: sanity check.
* libguile/generalized-vectors.c
- scm_c_generalized_vector_ref, scm_c_generalized_vector_set_x:
pos should be base when idx is lbnd. Furthermore, pos should be signed and
have its overflow checked; do this by handling the job to
scm_c_array_ref_1, scm_c_array_set_1_x.
* libguile/generalized-vectors.h
- fix prototypes.
