Output from a fix depth onward, instead of 3s. To avoid output that depends on timing, output currmove and similar only from depth > 30 onward. Current choice of 3s makes the output of the same search depending on the system load, and doesn't always start at move 1. Depth 30 is nowadays reached in a few seconds on most systems. closes https://github.com/official-stockfish/Stockfish/pull/5436 No functional change
