Add Bluetooth headset API to allow disabling audio route.

Browse Source 
This functionality is required by devices which have multiple profiles
using the SCO channel. For example, a device that is both a HFP AG and HF.
In this case, we must explicitly notify the profiles when they can acquire
the channel as they are not aware of each other. A similar change was
previously added to the Bluetooth Headset Client profile.
