This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP *cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData *td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e
