A new Singleton VirtualTerminal is added. It interacts with Logind to get the VTNr to take over. To get the signal to release and acquire the VT we use a signalfd with a QSocketNotifier to monitor for signals. The used signals must be blocked for all threads prior to startup otherwise they are delivered to secondary threads causing issues.
