Remove a bunch of difficult and tricky code to test legality of castle and ep moves and instead use a slower but simpler check against the list of generated legal moves. Because these moves are very rare the performance impact is small but code semplification is ver big: almost 100 lines of difficult code removed ! No functionality change. No performance change (strangely enough there is no even minimal performance regression in pgo builds but instead a slightly and unexpected increase).
