Some history fixes and tidy-up This adds the functions `update_refutations` and `update_quiet_histories` to better distinguish the two. `update_quiet_stats` now just calls both of these functions. The functional side of this patch is two-fold: 1. Stop refutations being updated when we carry out multicut 2. Update pawn history every time we update other quiet histories Yellow STC: LLR: -2.95 (-2.94,2.94) <0.00,2.00> Total: 238976 W: 61506 L: 61415 D: 116055 Ptnml(0-2): 846, 28628, 60456, 28705, 853 https://tests.stockfishchess.org/tests/view/66321b5ed01fb9ac9bcdca83 However, it passed in <-1.75, 0.25> bounds: $ python3 sprt.py --wins 61506 --losses 61415 --draws 116055 --elo0 -1.75 --elo1 0.25 ELO: 0.132 +- 0.998 [-0.865, 1.13] LLR: 4.15 [-1.75, 0.25] (-2.94, 2.94) H1 Accepted Passed LTC: LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 399126 W: 100730 L: 100896 D: 197500 Ptnml(0-2): 116, 44328, 110843, 44158, 118 https://tests.stockfishchess.org/tests/view/66357b0473559a8aa857ba6f closes #5215 Bench 2370967
