Speed up eval/move-gen/SEE; remove EvalLookForDanger, overhaul _EvalKing
SPRT-confirmed improvement (1814 games, st 4.0): candidate nps=1498118
vs head=1378448, avg depth 14.30 vs 13.87, ELO=+24.2+/-16.0,
LOWER95=0.5118, LLR=+3.126 crossing the H1 bound.
Most of the diff is non-semantic speed work across eval.c, generate.c,
movesup.c, see.c, probe.c and friends. Two real semantic changes:
removed EvalLookForDanger and overhauled _EvalKing's king-safety scoring.
