Remove the duplicated list of audio format names from m_option.c. Remove "long" audio format names, and let af_fmt2str() print the usual short format names. The long names were overly verbose, and were actually rarely user visible. The only difference between af_fmt2str() and af_fmt2str_short() is that the former prints unknown format values as hexadecimal string as fallback.
