New ways of passing encoded data between encoder and decoder. With this commit frames can be received partition-by-partition from the encoder and passed partition-by-partition to the decoder. At the encoder-side this makes it easier to split encoded frames at partition boundaries, useful when packetizing frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled, several VPX_CODEC_CX_FRAME_PKT packets will be returned from vpx_codec_get_cx_data(), containing one partition each. The partition_id (starting at 0) specifies the decoding order of the partitions. All partitions but the last has the VPX_FRAME_IS_FRAGMENT flag set. At the decoder this opens up the possibility of decoding partition N even though partition N-1 was lost (given that independent partitioning has been enabled in the encoder) if more info about the missing parts of the stream is available through external signaling. Each partition is passed to the decoder through the vpx_codec_decode() function, with the data pointer pointing to the start of the partition, and with data_sz equal to the size of the partition. Missing partitions can be signaled to the decoder by setting data != NULL and data_sz = 0. When all partitions have been given to the decoder "end of data" should be signaled by calling vpx_codec_decode() with data = NULL and data_sz = 0. The first partition is the first partition according to the VP8 bitstream + the uncompressed data chunk + DCT address offsets if multiple residual partitions are used.
