* libguile/generalized-vectors.h:
* libguile/generalized-vectors.c: Add a registry of vector constructors.
(scm_make_generalized_vector): New public function, constructs a
vector of a given type.
* libguile/bitvectors.c:
* libguile/bytevectors.c:
* libguile/srfi-4.c:
* libguile/strings.c:
* libguile/vectors.c: Register vector constructors.
* libguile/extensions.c (scm_init_extensions): No need to NULL the list
of registered extensions here, the static init does it for us. Allows
scm_c_register_extension to be called before scm_init_extensions.
* libguile/init.c (scm_i_init_guile): Move array initialization earlier,
so e.g. scm_init_strings has access to a valid list of array element
types when registering its vector constructor.
* libguile/Makefile.am:
* libguile/vectors.c:
* libguile/vectors.h:
* libguile/generalized-vectors.c:
* libguile/generalized-vectors.h: Move generic vector ops off into their
own file too. The implementation is now based on the generic
array-handle infrastructure.
* libguile.h:
* libguile/array-map.c:
* libguile/bitvectors.c:
* libguile/random.c:
* libguile/srfi-4.c: Update includers.
