Subject: Packet Number Randomization, 0, or 1

After a lot of back-and-forth on this subject, it seems like the value
of greasing outweighs any particular fixed value.  Let the network
have a 0 (or 1) and it will always expect that value, but if we
randomize then it has nothing.

To that end, I've a PR that increases the amount of randomization so
that we don't forget to randomize the high bit as well.

I have retained 0 as a valid potential value.  There doesn't seem to
be a strong consensus either way on this particular point, so I'm
leaving issue 832 be for the moment.
