Fix for shutdown -h. Change shutdown -r to use soft reboot (which does

not currently work, but there seems to be no way to make the hardware
reboot work reliably).  Also change the soft reboot to set the watchdog
timer so that if it *doesn't* work the hardware reboot gets used (it does
sometimes work...)
