(Yunqing Wang) This patch implements the row-based multi-threading within tiles in the encoding pass, and substantially speeds up the multi-threaded encoder in VP9. Speed tests at speed 1 on STDHD(using 4 tiles) set show that the average speedups of the encoding pass(second pass in the 2-pass encoding) is 7% while using 2 threads, 16% while using 4 threads, 85% while using 8 threads, and 116% while using 16 threads.
