The scalbn functions are similar enough that they can easily be made generic. Do so and f16 and f128 versions.

Requires #389, which has a few of its own dependencies.

f16 and f128 versions are untested, blocked until I can figure out how to do that with MPFR.

Edit: done in #392. I cherry picked that commit here but that one should probably merge first.

The `scalbn` functions are similar enough that they can easily be made
generic. Do so and `f16` and `f128` versions.
