Fix color fading: previously color could fade to red when
volume level for red color was actually never reached.
Display volume value on right side.
Use red color only if clipping is needed.

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.
