This change adds support for VP8 partitions in the video jitter buffer and the VP8 encoder and decoder wrappers. The feature is currently disabled by default since it requires a later version of libvpx. With this change the jitter buffer will also start keeping track of each packet header until decoding, and the VCMSessionInfo and VCMPacket objects will keep pointers into the encoded frame buffers.
