In the tile-coding experiment, 1. In tile decoder, added 2 set control APIs: VP10_SET_DECODE_TILE_ROW and VP10_SET_DECODE_TILE_COL. It allowed users to set the range of decoding at frame level. 2. Added a unit test while tile-coding experiment is on. It tested both tile encoder and decoder to make sure the encoded frame can be decoded as a whole frame or as independent tiles.
