Eric House de3107271d changes to make hashing work -- make sure unused space in structs is 0
-- and to detect when an incoming move doesn't make sense.  These
latter changes may not be necessary now that hash code is checked
first thing, but can't hurt, and there will be devices without hash
codes for a while.
