Adding AVB version of audio analyser.

Extracted a few configuration parameters that needed to change for the different board/codec combination.

Added ability for host to enable/disable streams. Re-worked the analysis to be a state machine so that it doesn't report glitches on stream off and can cope with stream on/off.
Updated the ramp code to have chan_id as unsigned like the rest of the code.
Work-around for BUG 15107 (arrays of interfaces issue).
Adding AVB configuration parameters.
Restructured the define includes to use audio_analyzer_conf.h. Added host app.
