/*
Note on the callback ownership.

In the Binder ownership model, the server implementation is kept alive
as long as there is any client (proxy object) alive. This is done by
incrementing the refcount of the server-side object by the Binder framework.
When it detects that the last client is gone, it decrements the refcount back.

Thus, it is not needed to keep any references to StreamCallback on our
side (after we have sent an instance to the client), because we are
the server-side. The callback object will be kept alive as long as the HAL server
holds a strong ref to IStreamCallback proxy.
