Don't copy a full Position object in print() Function move_to_san() requires the Position to be passed by referenced because a do/undo move is done inside the function to detect a possible mate and to add to the san string the corresponding '#' suffix. Instead of passing a copy of current position pass directly the original position object after const casting it. This has the advantage to avoid a costly Position copy, on the down side a bench test could report different searched nodes if print(move) is used, due to the additionals do_move() calls. No functional change.
