This patch reworks the unit test using the TestDriver audio driver. I
also recode the audio layer to match the design and drastically clean up
the code.

This would have to happen eventually. Might as well do it now!
I also updated the TestDriver test to match the changes I had to make.

The driver is used to select between gstreamer playback and a fake
playback mode used only when testing.
Currently the GSTDriver has empty functions. It will be implemented as
the audio.cpp file is updated.
