The biggest changes are: * Drop slice size and offset parameters, given the API doesn't seem to be designed to work per-slice. * Convert all the 1-bit syntax elements from structure fields to bits in a bit field flags field, following the other codec APIs. * Split the sequence, picture and slice headers to separate controls. This is build tested only, I haven't yet modified the existing Ffmpeg-based implementation, as I'd like to have some consensus first. Reviews and feedback are appreciated!
