Rename Position::list Use Position::square and Position::squares instead. This allow us to remove king_square(), simplify endgames and to have more naming uniformity. Moreover, this is a prerequisite step in case in the future we decide to retire piece lists altoghter and use pop_lsb() to loop across pieces and serialize the moves. In this way we just need to change definition of Position::square to something like: template<PieceType Pt> inline Square Position::square(Color c) const { return lsb(byColorBB[c]); } No functional change.
