Doug Barton de328d4a59 Avoid complicated tests of whether devices are present or not, and
enable all harvesting options by default since having them on for
devices not present doesn't hurt anything. Leave them on by default
since for the most part they are not producing noticable slowdown,
and are about to get a lot more efficient.

Re-order part of the cheesy entropy process in preparation for
its complete removal.
