Module Name:    src

Modified Files:
        src/sys/kern: kern_entropy.c

Log Message:
Make rndctl -E/-C reset entropy accounting.

If we don't trust a source, it's unreasonable to trust any entropy it
previously provided, and we don't have any way to undo only the
effects of that source, so just zero our estimate of the entropy in
the pool and start over.

(However, keep the samples already in the pool -- just treat them as
though they had zero entropy and start gathering more.)
