Does gerrit 17103 need to be cherry picked to flounder?

Current version of 4a-hal-generic is currently working with master and eel.
4a-hal-generic allows to configure an audio device only by writing a json configuration file.
The new hal are working with the 4a-softmixer to simplify mixer integration and use.

Only a few features are not available yet :

  • Check that external hal really exist at loading

  • Handling external hal status events.

  • Generation of an '4a-hal-manager' event when a hal status change.

  • Dynamic handling of USB devices.

  • Hal for alsa-bluetooth.
