Title: Updates to entropy device support

Allow the nature of the entropy device to be specified in the device

We classify this into `Strongest` for the best one, and `Strong`
and `Weak` if one is to be specifically selected. The default is
`Strongest`, which maps to `/dev/random` on Unix and currently a
weak (but functioning) source on Xen.
