    test: Introduce hs_client_note_connection_attempt_succeeded().
    
    This commit paves the way for the e2e circuit unittests.
    
    Add a stub for the prop224 equivalent of rend_client_note_connection_attempt_ended().
    
    That function was needed for tests, since the legacy function would get
    called when we attach streams and our client-side tests would crash with
    assert failures on rend_data.
    
    This also introduces hs_client.[ch] to the codebase.
