  30 /*  FUNCTION
  31         This function will shut down the operating system.
  32
  33     INPUTS
  34         action - what to do:
  35          * SD_ACTION_POWEROFF   - power off the machine.
  36          * SD_ACTION_COLDREBOOT - cold reboot the machine (not only AROS).
  37
  38     RESULT
  39         This function does not return in case of success. Otherwise is returns
  40         zero.
  41
  42     NOTES
  43         It can be quite harmful to call this function. It may be possible that
  44         you will lose data from other tasks not having saved, or disk buffers
  45         not being flushed. Plus you could annoy the (other) users.
