mining and the amount of space available for priority transactions.

For steady-state operation, this reduces the average time between wallet disk
writes from once per block to once per hour.

On -rescan, witness caches are only written out at the end along with the best
block, increasing speed while ensuring that on-disk state is kept consistent.

Witness caches are now never recreated during a -reindex, on the assumption that
the blocks themselves are not changing (the chain is just being reconstructed),
and so the witnesses will remain valid.
