Add a user-specific signal 'user0' which can be used for custom
functionality.
For now, only a single user-specific signal is supported. Additional
signals 'userX' or a more generic handling can be added in the future.
Also, the signal state can only be configured during the adapter
initialization and termination. Commands to change the signal state at
run-time may be added in the future.
