Subject: Remove 'si' StateInfo variable/parameter.
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=02e4697055519ed206fa76e4ef9abb9f156cd1a0;hp=02e4697055519ed206fa76e4ef9abb9f156cd1a0;p=stockfish

Remove 'si' StateInfo variable/parameter.

Since st is a member of position we don't need to pass it separately as
parameter.

While being there also remove some line in pos_is_ok, where
a copy of StateInfo was made by using default copy constructor and
then verified it's correctedness by doing a memcmp.
There is no point in doing that.
