The color fields were moved to another struct, and a way to propagate
timestamps and other input metadata was introduced, so the packet fifo
can be removed.

Add an option to disable film grain, and read the profile from the
sequence header referenced by the ouput picture instead of guessing
based on output pix_fmt.
