c7e14a279f dnxhddec: use dequantization formula from specs
The current one, while correct, does not yield the best possible
results. The specificiations suggest another formula, which results
in quality gains in the decoded output from fate tests. This
justifies changing said formula.

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.

30ce289074 movenc: Make tkhd "enabled" flag QuickTime compatible
QuickTime will play multiple audio tracks concurrently if this flag is
set for multiple audio tracks.  And if no subtitle track has this flag
set, QuickTime will show no subtitles in the subtitle menu.

405cc0d905 movenc: hotfix, dont store fiel for h264 / mpeg4-asp / dnxhd
Other software does not store it in this case, and the information
is provided by the codec stream

7d0e3b197c Write the fiel atom to mov files independently of the used video coded.
The QuickTime specification does not contain any hint that the atom
must not be written in some cases and both the QuickTime and the
AVID decoders do not fail if the atom is present.

This change allows to signal (visually) interlaced streams with
a codec different from uncompressed video.

As a side-effect, this fixes ticket #2202

69c25c9284 dnxhdenc: fix invalid reads in dnxhd_mb_var_thread().
Do not assume that frame dimensions are mod16 (or that height is mod32
for interlaced).
