334e2e2363 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.

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.

ed5bed4152 VC1: Fix intensity compensation performance regression
Fix https://trac.ffmpeg.org/ticket/3204

The problem was that intensity compensation was always used once it was
encountered. This is because v->next_use_ic was never set back to zero.
To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic.

This improved (restored) performance by 85% when decoding
