/// Core implementation of stopping an activity. Note this is a little
/// tricky because the server's meaning of stop is slightly different
/// than our client -- for the server, stop means to save state and give
/// it the result when it is done, but the window may still be visible.
/// For the client, we want to call onStop()/onStart() to indicate when
/// the activity's UI visibillity changes.
