This patch adjusts the various users of the 'Child' API to the changes on the account of the new non-blocking parent interface. It also removes the use of the no-longer-available 'Connection::KEEP_OPEN' feature. With the adjustment, we took the opportunity to redesign several components to fit the non-blocking execution model much better, in particular the demo applications. Issue #2120

* ROM sessions are closed.
