Stateless video codecs will require both the H264 metadata and slices in
order to be able to decode frames.

This introduces the definitions for a new pixel format for H264 slices that
have been parsed, as well as the structures used to pass the metadata from
the userspace to the kernel.

It seems Hans splitted the documentation and so this should now
go to Documentation/media/uapi/v4l/ext-ctrls-codec.rst.

Thanks for letting me know, it will be fixed in the next version.

I haven't seen any objections to renaming this to V4L2_PIX_FMT_H264_SLICE_RAW,
so if you could be so kind to push v5 with this rename (or similar), and also
rebasing to the master branch, I could then submit the H264 decoder support for
the Rockchip VPU.

I don't remember it, but yeah, this is fine by me. I'll adjust it and
send a new version.
