* blackconfig in .pro
* verify function to detect dangling states
* clear remote data when disconnected from network
* there was one problem that the data where not correctly cleaned up and hence new aircraft where not added again after a disconnect/reconnect from network
* it is not yet clear why data happens (dangling data), that is what the debugVerify function is for
* use correct status (the problem was that even not interpolated situations can be valid)
* track last position (SimObject), do not resend same position
* Before this commit, only the true altitude was known for an aircraft situation. The pressure altitude was not available anywhere yet.
* This caused a wrong altitude in radar clients.
* We fix this reading the pressure altitude from the simulators and set it in the own aircraft situation.
* MS Flight Simulators have the pressure altitude in the APIs available.
* For X-Plane and emulated simulator, we need to calculate it from the pressure at sea level.
* Finally, we use the new available pressure altitude to send it to the FSD server.
Maniphest Tasks: Ref T223
* CSimulatorInfo only initialized once and not over and over again in plugin info
* getSimulatorInfo() no longer virtual, as we can access the member CSimulatorInfo directly
* display exact simualtor in FSX/P3D driver
* renamed to identifierToSimulator and fixed typo "Identifier"
* Unlike in other cases, the remote aircraft provider slots are also very frequently called. So besides "style", it might be also useful here to avoid the extra MOC layers.
* Also renamed 2 web service signals and made web service connections Qt::QueuedConnection
* Do not start new event loop when shutting down
* FSX Listener end checking when shutting down
* in same step fixed: FSX driver can connect to P3D and FSX but not vice versa
* only add one object at a time
* only query object values (from sim) when object is confirmed
* better debug logging (can be switched on)
* physicallyAddRemoteAircraftImpl for better tracing of added objects
* wait until light state is available
* Motivation: slots no longer required, and in the driver the (small) slot overhead might matter
* renamed some members to better reflect future use
* timer intervals as constexpr
* fixed some typos and comments
