Add a mechanism for handling audio device configuration change
* Added new call handleDeviceConfigChange() to the Media Framework.
That call can be used when there are device configuration changes
(e.g., Bluetooth A2DP codec configuration has changed).
* Added new method AudioPolicyManager::handleDeviceConfigChange().
That method toggles the UNAVAILABLE/AVAILABLE connection state of the
device, so it can be reconfigured as appropriate - e.g., the audio
feeding parameters can be updated.
* Fix ALOGVV compilation errors when extra logging is enabled.
Test: A2DP streaming to headsets
