  SVN rev 217750 on 2011-01-23 14:22:26Z by jilles
  
  init: Only run /etc/rc.shutdown if /etc/rc was run.
  
  It does not make sense to shut down daemons that were not started. In
  particular, this fixes loss of mixer settings when shutting down using
  shutdown(8), init(8) or ctrl+alt+del from single-user mode.
  
  If /etc/rc reboots, /etc/rc.shutdown is not run.
  
  Also fix segfaults and other erratic behaviour if init receives SIGHUP or
  SIGTSTP while in single-user mode.
  
  This commit does not attempt to fix any badness with signal handlers
  (assumption that pointers can be read and written atomically, EINTR race
  condition). I believe it does not make this badness any worse.
