The goal is to distinguish between APIs provided by the generic layer to individual codecs and APIs internal to the generic layer. Start by moving ff_{decode,encode}_receive_frame() and ff_{decode,encode}_preinit() into this new header, as those functions are called from generic code and should not be visible to individual codecs.
