* Rewrite barriertest (the old one was useless|incomplete|partial|broken).
* Refactor barrier.py to reduce the public API surface to that which is
  actually required and used.  Cleans up some docstring style as well.

No functional changes.

This prepares for adding site_barrier support in a future patch.
