Ah ok, got it. I think it would be better to move utility/next_prior.hpp to
the Boost.Iterator module.

After the move, the Boost.Iterator module will have:
- include/boost/iterator/next_prior.hpp
  * Contains the actual code for `next` and `prior`.
    (Personally, I'd like to add `boost::prev` as a synonym of `boost::prior`.)
- include/boost/utility/next_prior.hpp
  * Just includes <boost/iterator/next_prior.hpp>.

This is how utility/declval.hpp was moved to the Boost.TypeTraits module.
