Commit ID 2218a5836a48a764e9b57f5996520b48e0b3d236

Rewrite do_null_move() Use a more traditional approach, along the same lines of do_move(). It is true that we copy more in do_null_move(), but we save the work in undo_null_move(). Speed test shows the new code to be even a bit faster. No functional change.
