lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value
The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.
INT_MAX is used here to denote the max allowed value for a sample format.
The opt-test code is changed to provide a valid reference example.

avformat/mov: Do not compute a grayscale palette for cinepak in mov.
This was never done for avi files, the decoder always produced
output no matter if a palette was computed or not.
Since a non-standard palette was needed, this simplifies the code.

vp9: fix crash if segmentation=1, keyframe/intraonly=1 and updatemap=0.
The reference map is never used in such cases, but we accidently copied
it anyway. This could cause crashes if this map has not yet been
allocated. Fixes trac ticket 3188.
