Space bonus and number of blocked pawns This patch refines the recently introduced interaction between the space bonus and the number of blocked pawns in a position. * pawns count as blocked also if their push square is attacked by 2 enemy pawns; * overall dependence is stronger as well as offset; * bonus increase is capped at 9 blocked pawns in position; passed STC https://tests.stockfishchess.org/tests/view/5e94560663d105aebbab243d LLR: 2.96 (-2.94,2.94) {-0.50,1.50} Total: 29500 W: 5842 L: 5603 D: 18055 Ptnml(0-2): 504, 3443, 6677, 3562, 564 passed LTC https://tests.stockfishchess.org/tests/view/5e95b383c2aaa99f75d1a14d LLR: 2.95 (-2.94,2.94) {0.25,1.75} Total: 63504 W: 8329 L: 7974 D: 47201 Ptnml(0-2): 492, 5848, 18720, 6197, 495 closes https://github.com/official-stockfish/Stockfish/pull/2631 bench 4956028
