b1fdf81c6e avcodec/jpeg2000dwt: use 32x32->64 multiplies in the 9/7i DWT 
This significantly improves the quality when the integer 9/7 transform
is used

1c495b0bf6 avcodec/jpeg2000: Move gainb handling into the quantization code 
thats how the specification defines it, this also improves numerical
accuracy of the integer wavelet implementation. It otherwise should
be equivalent, in case of overflows this can be reverted.

31c7c0e156 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.

7fc33dca39 libavformat: DNxHD in .mov, switch unspecified color_range to mpeg 
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.

e7fc5d53a0 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.

Output size of ffvhuff on various 4:2:0 sequences:
context=0,1/d:    851974   27226   1137281
