By using random values for ut_id, not based on the TTY name, it is
possible to run for example login(1) multiple times on the same TTY,
without overwriting any previous records.
The output of w(1) will then be as follows:
| 12:26PM up 2 days, 2:31, 5 users, load averages: 0.01, 0.03, 0.03
| USER TTY FROM LOGIN@ IDLE WHAT
| ed pts/2 mekker.80386.nl 12:26PM - w
| root pts/2 - 12:26PM - w
| root pts/2 - 12:26PM - w
| root pts/2 - 12:26PM - w

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible to the user anymore.
- Rename UTXF_* to UTXI_*, indicating the indexation, instead of using
the `antique' filename. If we ever get rid of utmp, it makes little
sense calling it by its old name.
The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).
This also means we must build libulog during bootstrap.

pam_sm_open_session(), avoiding false negatives when no tty is present.

time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:
- time(&ut.ut_time);
+ ut.ut_time = time(NULL);
and similar for ctime(3) etc. I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

- add __unused where appropriate
- PAM_RETURN -> return since OpenPAM already logs the return value.
- make PAM_LOG use openpam_log()
- make PAM_VERBOSE_ERROR use openpam_get_option() and check flags
for PAM_SILENT
- remove dummy functions since OpenPAM handles missing service
functions
- fix various warnings

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.
