From: "Lu, Han" <han.lu@xxxxxxxxx>
Add support for standalone mode where alsabat will run on a
different machine to the one being tested.
In standalone mode, the sound data can be generated, playback and
captured just like in normal mode, but will not be analyzed.
The alsabat being built without libfftw3 support is always work
in standalone mode.
The alsabat in normal mode can also bypass data analysis using
option "--standalone".
