Since in the C and HIDL APIs the method for opening a stream
receives the device to connect to, some legacy HAL implementations
took an advantage of that. In AIDL APIs device port connection
process is more dynamic and independent of the stream creation.
To simplify porting of legacy implementations to AIDL, a helper
class StreamSwitcher is added. It emulates the legacy behavior
by allowing to postpone the stream implementation creation until
the connected device is known. Until that moment, it exposes
to the client a stub implementation of the stream interface.
