Simplify interfaces to scm_TYPEvector_(writable_)elements

Browse source 
Nothing is lost in these since the functions already required true typed
vectors, the extra arguments didn't serve any purpose.

Changing my mind from (vec) to (vec, lenp), though. Will fix
vector/bitvector next.

* libguile/srfi-4.h: scm_TYPEvector_(writable_)elements take (vec, lenp).
* libguile/srfi-4.c: Fix implementation.
* libguile/bitvectors.c: Fix use.
* test-suite/standalone/test-srfi-4.c: Fix old test and write variant
  with full array handle interface.
* doc/ref/srfi-modules.texi: Fix doc for srfi-4
  scm_TYPEvector_(writable_)elements.
