059fc2d9da avcodec/mjpegenc: Include all supported pix_fmts in mpegenc pix_fmts
Currently said list contains only the pixel formats that are always
supported irrespective of the range and the value of
strict_std_compliance. This makes the MJPEG encoder an outlier as all
other codecs put all potentially supported pixel formats into said list
and error out if the chosen pixel format is unsupported. This commit
brings it therefore in line with the other encoders.

The behaviour of fftools/ffmpeg_filter.c has been preserved. A more
informed decision would be possible if colour range were available
at this point, but it isn't.

bab6b88ebf avcodec/mjpegenc_common: Move stuff only used by mjpegenc.c to it
This allows to make ff_init_uni_ac_vlc static;
ff_mjpeg_encode_picture_frame has also been made static, but it could
always have been made static.

6eae9c1d39 avcodec/jpegtables: Move ff_mjpeg_build_huffman_codes to mjpegenc_common
Since g2meet.c doesn't use it any more, only encoders use it and
the place for their common code is mjpegenc_common.c.

2862b63783 lavc: Move prediction_method to codec private options
This options is only used by huffyuv, ffvhuv, jpegls, mjpeg,
mpegvideoenc, png, utvideo.
It is a very codec-specific options, so deprecate the global variant.
Set proper limits to the maximum allowed values, and update utvideoenc
tests to use the new option name.
