Some initial cleanup to aid testing and debug. Pull code to choose temporal or spatial encoding out of encodeframe.c into a dedicated function in segmentation.c. For now disable broken temporal mode. Move the coding of "temporal_update" flag and only transmit if segment map update is indicated. Rename the functions read_mb_features() and write_mb_features() to read_mb_segid() and read_mb_segid() as they only read and write the macroblock segment id not any of the features.
