This is the default implementation of Bluetooth Audio Hal v2, and 3
providers are defined.
* BluetoothAudioProvider is the default provider, which is a stub when
no SessionType matched.
* A2dpSoftwareAudioProvider uses to replace the old A2DP legacy module
and uses IPC via HIDL interface between Bluetooth stack and Audio HAL.
* HearingAidAudioProvider uses to replace the Hearing Aids module which
uses UNIX socket as IPC and now there is HIDL based interface.
There is also a shared library named "libbluetooth_audio_session.so" to
provide the linkage directly between this HIDL and its HAL module,
bluetooth_audio. With this library, we can break the library dependency
and guarantee those symbols of libraries while compiling.

Generalized Bluetooth Audio HAL interface.
It is similar to the original android.hardware.bluetooth.a2dp@1.0
interface with the following modifications:
* The session type can be one of the following:
- A2DP Software Encoding Datapath
- A2DP Hardware Encoding Datapath
- Hearing Aid Software Encoding Datapath
* For Hardware Offload Datapath (A2DP), the HAL interface is used only
for the control path
* For Software Encoding Datapath (A2DP or Hearing Aid), the HAL
interface is used for both the control and data paths
* Added Delay Report support: IBluetoothAudioHost.getPresentationPosition()
that was missing in the original android.hardware.bluetooth.a2dp@1.0
HAL interface.
* Removed "oneway" calls to avoid potential reordering of HAL calls:
b/111244402
* Updated SBC-specific codec configuration
* Added AAC-specific and LDAC-specific codec configuration
* Reorganized the original CodecConfiguration into two sections:
- PcmDataConfiguration: Audio PCM data configuration
- EncodedDataConfiguration: Encoded audio data codec configuration.
It is used only if the HAL is responsible for encoding the PCM audio
data.
* Added new HAL IBluetoothAudioProvidersFactory.
It is used to open an audio provider for an audio session as specified by
the session type and the codec configuration as negotiated with the
remote device.
