Mark Johnston fa8db724ae random: Treat writes to /dev/random as separate from /entropy ...

RANDOM_CACHED is overloaded to refer both to entropy obtained from files
loaded by the boot loader, and entropy obtained via writes to
/dev/random.  Introduce a new source, RANDOM_RANDOMDEV, to refer to the
latter.  This is to enable treating RANDOM_CACHED as a special case in
the NIST health test implementation.

Update the default harvest_mask in rc.conf to include RANDOM_RANDOMDEV,
preserving the old behaviour of accepting writes to /dev/random.

Bump __FreeBSD_version for modules which register a pure source, since
all of their values have now shifted.
