- Don't log dlopen() failures, since they're rarely interesting;
instead, log a failure if no module was found at all.
- When loading a versioned module, store its logical name in the
module structure rather than its physical name, since it will be
looked up by its logical name if it's needed again.
- Initialize module->next->prev when adding a module to the cache.
- Set modules to NULL when releasing the last module in the cache.

support for module versioning. OpenPAM will prefer a PAM module with
the same version number as the library itself to one with no version
number at all.
