/* opietest.c: Quick, though definitely not complete, regression test for
               libopie. This is intended to catch two things:

	(1) when changes break something
        (2) if some system wierdness (libc, compiler, or CPU/hardware) is
            not getting along at all with OPIE.

        It's safe to say that, if tests fail, OPIE isn't going to work right
on your system. The converse is not such a safe statement.

        History:

	Modified by cmetz for OPIE 2.4. Use struct opie_key for key blocks.
	Modified by cmetz for OPIE 2.31. Added a couple of new checks,
		removed a few commented-out checks for functions that
		no longer exist, added test-skip capability.
	Modified by cmetz for OPIE 2.3. Use new calling conventions for
		opiebtoa8()/atob8(). opiegenerator() outputs hex now.
	Modified by cmetz for OPIE 2.22. Test opielock()/opieunlock()
		refcount support.
	Created by cmetz for OPIE 2.2.
