avformat/movenc: Move avid DNxHD padding to the correct spot
...
Outputting DNxHD into .mov containers 'corrupts' following atoms until end of stsd
ffmpeg and qtdump could not decode pasp/colr atoms in the files made by ffmpeg,
when outputting DNxHD due to the incorrect padding placement. Now we add the
padding in the correct place
Tidy up FATE changes due to padding changes.

Avid prefers mpeg range [16-235] by default this change brings
ffmpeg into line with that. To obtain the old behaviour use
'-color_range jpeg' on the command line prior to the ouput
filename.

huffyuv: change statistics initialization

Normally, a Laplace distribution is more typical of the residuals
encoded, but for noisy input, it's both better and simpler to be
safe and use a 1/d^2 distribution. Second hunk could use some
renormalization but it has effectively little impact.
