Move 50 moves counter to initiative. simplify the usage of the 50 moves counter, moving it frome the scale factor to initiative. This patch was inspired by recent games where a blocked or semi-blocked position was 'blundered', by moving a pawn, into a lost endgame. This patch improves this situation, finding a more robust move more often. for example (1s searches with many threads): ``` FEN 8/p3kp2/Pp2p3/1n2PpP1/5P2/1Kp5/8/R7 b - - 68 143 master: 6 bestmove b5c7 6 bestmove e7e8 12 bestmove e7d8 176 bestmove e7d7 patch: 3 bestmove b5c7 5 bestmove e7d8 192 bestmove e7d7 ``` fixes https://github.com/official-stockfish/Stockfish/issues/2620 the patch also tests well passed STC LLR: 2.94 (-2.94,2.94) {-1.50,0.50} Total: 50168 W: 9508 L: 9392 D: 31268 Ptnml(0-2): 818, 5873, 11616, 5929, 848 https://tests.stockfishchess.org/tests/view/5ebb07287dd5693aad4e680b passed LTC LLR: 2.93 (-2.94,2.94) {-1.50,0.50} Total: 7520 W: 981 L: 870 D: 5669 Ptnml(0-2): 49, 647, 2256, 760, 48 https://tests.stockfishchess.org/tests/view/5ebbff747dd5693aad4e6858 closes https://github.com/official-stockfish/Stockfish/pull/2666 Bench: 4395562
