73ce8162f3 avfilter/vf_scale: set proper out frame color range 
Prevents that following scalers in the filter chain will do unintentional color range conversions.
Fixes Ticket #5096

6aaac24d72 avfilter/all: propagate errors of functions from avfilter/formats 
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.

Fixes: CID 1325680, 1325679, 1325678.

552faecf4b vf_scale: conditionally override chroma position 
For yuv420p, the chroma position is unilaterally overriden, even
if ffmpeg's command-line explicitly set it. To fix this, override
only if the value is the default one.

Regression since 1515bfb3.

862f33c10e vf_scale: use the pixfmt descriptor API 
Avoid using AV_PIX_FMT_NB, since that hardcodes the number of pixel
formats into lavfi and will break when a shared lavu is updated, adding
new pixel formats.
