7a9b4427b5 avfilter/avf_showvolume: fix several issues
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.

0fe5dcd660 avfilter/avf_showvolume: use log10 instead of log()/M_LN10
This is likely more precise and conveys the intent better.

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.
