Build structure for contribified Linux-PAM, plus some home-grown
modules for FreeBSD's standard authentication methods. Although the Linux-PAM modules are present in the contrib tree, we don't use any of them. The main library "libpam" is composed of sources taken from three places. First are the standard Linux-PAM libpam sources from the contrib tree. Second are the Linux-PAM "libpam_misc" sources, also from the contrib tree. In Linux these form a separate library. But as Mike Smith pointed out to me, that seems pointless, so I have combined them into the libpam library. Third are some additional sources from the "src/lib/libpam" tree with some common functions that make it easier to write modules. Those I wrote myself. This work has been donated to FreeBSD by Juniper Networks, Inc.
