axfer: add a unit test for mapper interface
In former commits, mapper module gets supports of muxer/demuxer for single/multiple targets for playback source or capture destination. This commit adds a unit test for them. This includes positive test cases only. The test cases actually generate I/O to file systems for many test cases. It takes a bit long time to finish.
