Bring in some behind-the-scenes development, mainly By Arthur Mesh,
the rest by me.
o Namespace cleanup; the Yarrow name is now restricted to where it
really applies; this is in anticipation of being augmented or
replaced by Fortuna in the future. Fortuna is mentioned, but behind
#if logic, and is ignorable for now.
o The harvest queue is pulled out into its own modules.
o Entropy harvesting is emproved, both by being made more conservative,
and by separating (a bit!) the sources. Available entropy crumbs are
marginally improved.
o Selection of sources is made clearer. With recent revelations,
this will receive more work in the weeks and months to come.
