AudioService: anonymize Bluetooth MAC addresses
Make sure APIs returning AudioDeviceAttributes from AudioService
anonymize the Bluetooth MAC addresses because those are considered
privacy sensitive.
Only expose the full MAC address to system and apps with BLUETOOTH_CONNECT
permission.
setters, getters and listeners for preferred device for strategy,
preferred device for capture preset and mute await connection are
modified:
- when entering AudioService, full MAC addresses are retrieved based on the
known Bluetooth devices stored in AudioDeviceInventory.mDeviceInventory
- when exiting AudioService, MAC addresses are anonymized if the client
app does not have BLUETOOTH_CONNECT permission or is not a system component
APIs based on AudioDeviceInfo do not need to be modified as the
AudioDeviceInfo MAC address is for the AudioPort cached in the app
process and AudioPorts are anonymized by the native audioserver before
being returned to client apps.
