Import OpenPAM.

The basics (pam_start(), pam_end(), pam_strerror(), item-,
data- and environment-related functions and the six PAM
primitives) are implemented. A stub is provided for
pam_get_user(), which is not yet implemented. Stubs are also
provided for XSSO mapping and secondary authentication, though
they are not built and will probably not be implemented for
quite some time.
