The ulog_login_pseudo(3) and ulog_logout_pseudo(3) interfaces provide a functionality identical to what libutempter has to offer. Just transform libutempter's calls into the before mentioned functions. libutempter doesn't work with utmpx, so instead of fixing I thought the easiest way would be to integrate this functionality. libutempter is used by applications like xterm and the KDE libraries, so if I ever change the underlying file format, these applications will keep working automatically. Also increase __FreeBSD_version to indicate the addition (as well as the import of libulog).
