New machine-independant /dev/random driver.
This is work-in-progress, and the entropy-gathering routines are not yet present. As such, this should be viewed as a pretty reasonable PRNG with _ABSOLUTELY_NO_ security!! Entropy gathering will be the subject of ongoing work. This is written as a module, and as such is unloadable, but there is no refcounting done. I would like to use something like device_busy(9) to achieve this (eventually). Lots of useful ideas from: bde, phk, Jeroen van Gelderen Reviewed by: dfr
