goutmp - Minimal bindings to C stdlib pututmpx(), getutmpx() (/var/log/wtmp) and /var/log/lastlog

Any Go program which allows user shell access should update the standard UNIX files which track user sessions: /var/log/wtmp (for the 'w' and 'who' commands), and /var/log/lastlog (the 'last' and 'lastlog' commands).
