Introduce voting system for best move selection Introduce voting system for best move selction in multi-threads mode. Joint work with Stefan Geschwentner, based on ideas introduced by Michael Stembera. Moves are upvoted by every thread using the margin to the minimum score across threads and the completed depth. First thread voting for the winner move is selected as best thread. Passed STC, LTC. A further LTC test with only 4 threads failed with positive score. A LTC with 31 threads was stopped with LLR 0.77 after 25k games to avoid use of excessive resources (equivalent to 1.5M STC games). Similar ideas were proposed by Michael Stembera 2 years ago #507, #508. This implementation seems simpler and more understandable, the results slightly more promising. Further possible work: 1) Tweak of the formula using for assigning votes. 2) Use a different baseline for the score dependent part: maximum score or winning probability could make more sense. 3) Assign votes in `Thread::Search` as iterations are completed and use voting results to stop search. 4) Select best thread as the threads voting for best move with the highest completed depth or, alternatively, vote on PV moves.
