Add support for Multi-A2DP state machines per device
* Remove mStateMachine and use a single A2dpStateMachine instance per device
* Cleanup/simplify A2dpStateMachine internals - the BluetoothDevice per
state machine doesn't change.
* Send the state changed broadcast message on enter() in a new state
This fixes timing ordering issue exposed by some of the unit tests
* Remove a state machine when bonding for a device is removed
* Add a mechanism to set the active device
* Add a mechanism to track the maximum number of connected devices
* Updated the codec-related APIs to take a BluetoothDevice argument:
- getCodecStatus()
- setCodecConfigPrefereice()
- enableOptionalCodecs()
- disableOptionalCodecs()
* Add A2dpServiceTest unit tests for A2dpService
* Add ActiveDeviceManager that is responsible for keeping track of the
connected devices and select which device is active.
Also:
* Updated the JNI codec-related calls to use const reference
instead of a pointer
* Additional cleanup
