When reseeding the DPRNG, we're supposed to hash the current key and
some accumulated entropy twice and use that as the new key.  Due to a
typo, we were using the output of the first hash round instead of the
second.  Correct this, but eliminate temp[] since we can reuse hash[].
Also add comments explaining what is going on and why.
