Add a function that wraps hbitmap_iter_next() and always calls it in
26ba25
non-advancing mode first, and in advancing mode next.  The result should
26ba25
always be the same.
26ba25
26ba25
By using this function everywhere we called hbitmap_iter_next() before,
26ba25
we should get good test coverage for non-advancing hbitmap_iter_next().
