Add weak-vector-length, weak-vector-ref, weak-vector-set!
* libguile/weaks.c (scm_is_weak_vector, scm_c_weak_vector_length):
(scm_c_weak_vector_ref, scm_c_weak_vector_set_x): New interfaces for
dealing with weak vectors from C.
(scm_weak_vector_length, scm_weak_vector_ref, scm_weak_vector_set_x):
New Scheme interfaces to weak vectors; to be used instead of
vector-length, vector-ref, etc.
* module/ice-9/weak-vector.scm: Export the new interfaces.
* doc/ref/api-memory.texi (Weak vectors): Document them.
