bitvector work

* test-suite/Makefile.am:
* test-suite/tests/bitvectors.test: Add a new file to test bitvectors.

* libguile/uniform.c (scm_c_uniform_vector_length): Don't call
  scm_uniform_vector_elements, as we don't need to be able to access the
  elements with pointers to bytes. Fixes uniform-vector-length on
  bitvectors.
