    Switch Bluetooth HAL policy to _client/_server · 168435fe
    Alex Klyubin authored
    This switches Bluetooth HAL policy to the design which enables us to
    conditionally remove unnecessary rules from domains which are clients
    of Bluetooth HAL.
    
    Domains which are clients of Bluetooth HAL, such as bluetooth domain,
    are granted rules targeting hal_bluetooth only when the Bluetooth HAL
    runs in passthrough mode (i.e., inside the client's process). When the
    HAL runs in binderized mode (i.e., in another process/domain, with
    clients talking to the HAL over HwBinder IPC), rules targeting
    hal_bluetooth are not granted to client domains.
    
    Domains which offer a binderized implementation of Bluetooth HAL, such
    as hal_bluetooth_default domain, are always granted rules targeting
    hal_bluetooth.
    
    Test: Toggle Bluetooth off and on
    Test: Pair with another Android, and transfer a file to that Android
          over Bluetooth
    Test: Pair with a Bluetooth speaker, play music through that
          speaker over Bluetooth
    Test: Add bluetooth_hidl_hal_test to device.mk, build & add to device,
          adb shell stop,
          adb shell /data/nativetest64/bluetooth_hidl_hal_test/bluetooth_hidl_hal_test
