fbb222c9bc axfer: test: fix invalid comparison of 64 bit storage in ILP32 data type
In system V ABIs with ILP32 data model, bit shift for '1ul' can brings
undefined behaviour when the calculation result is over 32 bit width.

This commit fixes the bug.

This commit fixes uninitialized return value from a call of test_mux() and
text_demux() to suppress warnings below:

39d1ab8a0c 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.
