avcodec, avformat: deprecat
Since we've disabled side data merging in ffmpeg.c, this really changes
nothing.

Hello!
There are 3 problems with DITHER_COPY macro in libswscale/swscale_unscaled.c:
1) there is overflow in dithering from 12-bit to 10-bit (output value > 1023);
2) for limit range the lower limit is not respected, for example from 10-bit to
8-bit value 64 is converted to 15;
3) for many iterat
These values are defined to be 32bit in the specification,
so it makes more sense to store them as fixed width.
