- Just like struct utmp, store strings inside struct utmpx itself. This is needed to make things like pututxline() work. - Add ut_id and ut_pid fields, even though they have little use in our implementation. - It turns out our "reboot" wtmp entries indicate a system boot, so remove REBOOT_TIME - Implement getutxline() and pututxline - Add getutxuser() and setutxfile(), which allows us to crawl wtmp and lastlog files as well. - Add _ULOG_POSIX_NAMES, so we can already use the POSIX names if we really want to.
