Retire the misdesigned StepAttacks array.
StepAttacks is misdesigned, the color dependance is specific to pawns, and trying to generalise to king and knights, proves neither useful nor convinient in practice.
So this patch reformats the code with the following changes:
- Use PieceType instead of Piece in attacks_() functions
- Use PseudoAttacks for KING and KNIGHT
- Rename StepAttacks into PawnAttacks
Original patch and idea from Alain Savard.
No functional change.
