Implement OpenBSD authentication using bsd_auth(3).
OpenBSD does not have nor use pam(8) for password authentication but instead uses bsd_auth(3): add a bsd_auth authentication scheme to make locking possible. This has been a part of gnome-screensaver already but was probably removed at one point. This is mostly identical to that code, with some minor modifications.
