Commit ID 748791f80dbc29793e473e3e9eda83ffa0afcfaa
Author Shahin M. Shahin

Fix `go mate x` in multithreading Fixes two issues with master for go mate x: - when running go mate x in losing positions, master always goes to the maximal depth, arguably against what the UCI protocol demands - when running go mate x in winning positions with multiple threads, master may return non-mate scores from the search (this issue is present in stockfish since at least sf16) The issues are fixed by (a) also checking if score is mate -x and by (b) only letting mainthread stop the search for go mate x commands, and by not looking for a best thread but using mainthread as per the default.
