Previously all own aircraft values were request via single DBus calls.
Since DBus allows up to 8 values in its reply, use this mechanism
to group the requests and reduce the amount of single calls.
QtDBus was the main component of xswiftbus' Qt dependency. This is the
first preparation step to get xswiftbus Qt free.
The new implementation is based on the low level libdbus library, which
was also in use by QtDBus itself. But instead of QtDBus, we use now a thin
C++ wrapper. To keep DBus handling async, libevent is used to monitor
timeouts and fds.
* 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
Summary:
Refactored parts of CAircraftModelLoaderXPlane::parseFlyableAirplanes into static method extractAcfProperties that can be called by xswiftbus.
Used extractAcfProperties in xswiftbus to provide the model string to the driver. Implemented CSimulatorXPlane::ps_emitOwnAircraftModelChanged.
Implements T74.

Summary:
I wanted to rename xbus because its relation to //swift// is not immediately clear from the name.
xswiftbus seems reasonable.
