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.
