cleanup unreferenced functions

This is a mechanical cleanup of unused functions.  In the case where the
functions are referenced (in comment form), I've simply commented out the
functions.  A second pass to clean that up is warranted.

The functions which are otherwise unused have been removed.  Some of these were
introduced in the initial commit and not in use prior to that point!
