applications linked with Linux-PAM will still work.
Remove pam_get_pass(); OpenPAM has pam_get_authtok().
Remove pam_prompt(); OpenPAM has pam_{,v}{error,info,prompt}().
Remove pam_set_item(3) man page as OpenPAM has its own.

doesn't really make any difference, except it matches wtmp(5) better.
Don't do anything in pam_sm_close_session(); init(8) will take care of
utmp and wtmp when the tty is released. Clearing them here would make it
possible to create a ghost session by logging in, running 'login -f $USER'
and exiting the subshell.
