Rewrite syzygy in C++ Rewrite the code in SF style, simplify and document it. Code is now much clear and bug free (no mem-leaks and other small issues) and is also smaller (more than 600 lines of code removed). All the code has been rewritten but root_probe() and root_probe_wdl() that are completely misplaced and should be retired altogheter. For now just leave them in the original version. Code is fully and deeply tested for equivalency both in functionality and in speed with hundreds of games and test positions and is guaranteed to be 100% equivalent to the original. Tested with tb_dbg branch for functional equivalency on more than 12M positions. stockfish.exe bench 128 1 16 syzygy.epd Position: 2016/2016 Total 12121156 Hits 0 hit rate (%) 0 Total time (ms) : 4417851 Nodes searched : 1100151204 Nodes/second : 249024 Tested with 5,000 games match against master, 1 Thread, 128 MB Hash each, tc 40+0.4, which is almost equivalent to LTC in Fishtest on this machine. 3-, 4- and 5-men syzygy bases on SSD, 12-moves opening book to emphasize mid- and endgame.
