Implement speaker enable/disable on jack (un)plug
The implementation is not very complicated but there are a few things worth noting. There was a previous "speaker enable" setting but it was a boolean. I decided to replace it with a choice setting that has 2 options (on, off) if headphones cannot be detect on this target, or 3 options (on, off, auto) if we can detect headphones. This will break the old setting on target that cannot detect jack but it makes the code more uniform and avoid maintaining two settings with more #ifdef. The third option (auto) uses the LANG_AUTO text, which I think is clear enough (disable speaker on jack plug). In order to avoid code duplication (both in apps and firmware), I decided to keep the audiohw_enable_speaker function as-is: it takes a boolean and doesn't care about the speaker policy. I introduced a new audio_enable_speaker that takes directly the mode (which follows the setting encoding): 0=off, 1=on and 2=auto. This way one calls audio_enable_speaker and it changes the speaker once to reflect the request mode. The apps code then uses this function in the places where it makes sense: on setting load, setting change and jack (un)plug event. Change-Id: I027873f698eb4bc365d7c02b515297806355d9e2
