GitLab

Part of simplification of the window setup plugin.
Also, to avoid having to maintain two similar plugins, the differences from the former VIDC oriented Sound Setup are integrated
* If SoundControl module is running behave as before
* If no SoundControl but there is a VIDC, adapt to add
  + 16b/8b hardware option
  + oversampling option
  + don't permit muting of the (one and only) mixing channel
  + the mixing channel governs the *VOLUME and corresponding CMOS bits
* Updated common functions from other plugins
* Use definitions from HighFSI, OsBytes, CMOS in place of local ones

Tested on a Risc PC (ie. VIDC style) and Beagleboard xM (ie. mixer style).
