Subject: [PATCH] Wired/BT headset: make ringtone audio focus customizable [1/2]

Allow to choose where to play incoming call ringtones from
if a wired or BT headset is plugged in.
Mode 0: play the ringtone from the headset but only if music is playing (if no
music, play from speakerphone)
Mode 1 (default aosp behavior): always play the ringtone from both speakerphone
and headset

thanks @xyyx for unlinking the code form the Telecomm tree
