axfer: add an option to finish transmission at XRUN
In aplay, '--fatal-errors' option has an effect to give up recovery of PCM substream from XRUN state. This commit adds support for this option. In original implementation, this option brings program abort. This seems to generate core dump of process VMA. However, typically, XRUN comes from timing mismatch between hardware and application, therefore core dump has less helpful. This commit finishes this program in usual way with this option at XRUN.
