- Added esd flavor, adding esound support to madplay
- Added -b (--bit-depth) option and -i (--ignore-crc) option to madplay
- Added a new mad_stream_errorstr() API function to libmad for retrieving
a string description of the current error condition.
- Changed the audio_wave module to initially write ~0 length rather than
0, for better compatibility when output is piped to another program.
