The existing code is pretty ancient and is unreliable on modern hardware.
Generally it will hang.
We can use port 0xcf9 to initiate reset on more modern hardware (say in the
last 10 years). Update the reset_cpu() function to do this, and add a new
'full reset' function to perform a full power cycle.
