import/switch of: init, getty, reboot, halt, shutdown, wall, last changes: . change reboot() call to netbsd prototype and args . allows pristine <utmp.h> . use clean <sys/reboot.h> instead of <minix/reboot.h> . implement TIOCSCTTY for use by getty so getty can get controlling terminal from init's child(ren) . allow NULL envp for exec Change-Id: I5ca02cb4230857140c08794bbfeba7df982c58a3
