alsa: rework mixer logic
Completely rework mixer logic. This now allows controlling a full set of elements from a single sink's volume slider/mute button. This also introduces sink and source "ports" that can be used to choose different input or output ports with the UI. (i.e. "mic"/"line-in" or "speaker"/"headphones". The mixer paths and device maps are now configered in external configuration files and can be tweaked as necessary.
