no futility pruning for certain captures if the PvNode has a draw eval.

Consolidate all attacks bitboards
This is a non-functional simplification that simplifies getting attacks bitboards.
* consolidates all attacks to attacks_bb (remove Position::attacks_from(..)).
* attacks_bb<PieceType>(square) gets pseudo attacks
* attacks_bb<PieceType>(square, bitboard) gets attacks considering occupied squares in the bitboard).
* pawn_attacks_bb(Color, Square) gets pawn attacks like other pawn attack bitboards.
* Wraps all access to PawnAttacks arrays and PseudoAttacks arrays and adds asserts as appropriate.

Use posix_memalign for Apple Silicon instead of _mm_malloc
fails to build on that target, because of missing Intel Intrinsics.
macOS has posix_memalign() since ~2014 so we can simplify the code and just use that for all Apple platforms.

According to my first tests, the new network from Sergio SV 1046 is strong, but not as strong as SV 1739. I think SV 1739 is currently the strongest network at the moment. Maybe someone has the opportunity to test it with other strong networks.

Each tester has different versions of strong networks ,and I have the strongest one-the last network.
Processor:Intel Core i5-7600K, GHz:4.20 , Сore:1, Gui:Fritz-11, Games:100, Time:1+1, Book:Off ,Endgame tables:Syzygy 3-4-5, Hash:128 MB, Ponder:Off.
New network from Sergio:

20200908-1733.bin 2020-09-08 18:41 20M

put the champion 1046 against the new network 1733. Results will be available later

Hi Bro Lisandr..
Thx for the link.. but I want to ask u something.. about Chess Engine ( for Android )
Which Engines u think are the strongest with it's own book ? .is it Brainfish ? Or Bluefish ? Or what ?
I have a little confused here to decide which one are the best for any Android devices

My opinion is Stockfish, the rest of its copies, clones, which is better than the original or a copy?

Woww.. I'm so surprised.. because I've just heard that there is an Engine of Stockfish which has it's own book..
Can u tell me which Stockfish that u mentioned ?
Or perhaps if its not bothering u, the link of it's Engine would be so much grateful
Stockfish 12 of course what else. There is a Stockfish polyglot in which you can add several books . I don't know what kind of book it is. I know that there is a network, and I do not use books, why, if there is a strong network.
