[PATCH 5/5] Add fast connectable support to HFP

[Dmitriy Paliy <dmitriy.paliy@nokia.com>]

Audio.conf is updated to support fast connectable mode. Set
FastConnectable to true to enable and to false to disable. Headset
initialization and call indicators are updated respectively. It is
disabled by default.
