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. Bug: 111519504 Bug: 122503379 Test: boot and manual test Change-Id: I54d86291482b7fb041a3ac3e171b68a4ed7bfa07
