Following up on this on (time flies!) I have moved the code
up into the arch-independent hw_random code and split it into 3
patches. First generate the injection point for true HWRNGs,
then create a thread that makes use of it and finally add
some simple on/off switch. The latter could be replaced with
something far more sophisticated if desired.
