  Don't leave the console TTY constantly open.
  
  When we leave the console TTY constantly open, we never reset the
  termios attributes. This causes output processing, echoing, etc. not to
  be reset to the proper values when going into single user mode after the
  system has booted. It also causes nl-to-crnl-conversion not to take
  place during shutdown, which causes a `staircase effect'.
  
  This patch adds a new TTY flag, TF_OPENED_CONS, which is set when the
  TTY is opened through /dev/console. Because the flags are only used by
  the kernel and the pstat(8) utility, I've decided to renumber the TTY
  flags. This shouldn't be an issue, because the TTY layer is not yet part
  of a stable release.
