Now pam_nologin(8) will provide an account management function

instead of an authentication function.  There are a design reason
and a practical reason for that.  First, the module belongs in
account management because it checks availability of the account
and does no authentication.  Second, there are existing and potential
PAM consumers that skip PAM authentication for good or for bad.
E.g., sshd(8) just prefers internal routines for public key auth;
OTOH, cron(8) and atrun(8) do implicit authentication when running
a job on behalf of its owner, so their inability to use PAM auth
is fundamental, but they can benefit from PAM account management.

Document this change in the manpage.

Modify /etc/pam.d files accordingly, so that pam_nologin.so is listed
under the "account" function class.

Bump __FreeBSD_version (mostly for ports, as this change should be
invisible to C code outside pam_nologin.)
