Before the next release:

 - Complete the transition from PAM_LOG_DEBUG to PAM_LOG_LIBDEBUG.

Whenever:

 - Implement mechanism to enable / disable optional features.  Use it
   to disable strict error checking so pamtest and unit tests can do
   things that we don't allow in production.

 - Rewrite the module-loading code.
