llimport(8): Import lastlog into utmpx

[Ed Schouten]

Hi all,

I think not long after I replaced utmp with utmpx, I got requests to add
utilities to convert the old utmp databases to the new formats. I added
wtmpcvt(1) for /var/log/wtmp*, but I didn't add any tools for the other
databases. Even though it's a bit overdue (more than one year later?), I
think it wouldn't be a bad idea to add a utility to import lastlog for
people who are going to upgrade from 7.x/8.x to 9.0.

I've written a utility called llimport(8), which imports entries from
lastlog into utx.lastlogin for users which do not already have an entry
in the latter. I've also added an rc-script, which executes llimport
when /var/log/lastlog is present and renames the old database to
/var/log/lastlog.old.

Any objections if I commit the following patch to HEAD one of these
days? I will remove it from HEAD not long after we release 9.0, since an
upgrade from 8.x to 10.x should go through 9.x anyway.

It would be nice if someone could look at the rc script. I think it
should be okay, but it's not a part of the tree I'm familiar with.
