(based on FSX testing)
* Only send changed situation to SIM
* Split sending of parts / situations
* Only send parts with a reduced frequency (means slower as positions)
* Mark geodetic height as null for default values (the value is usually unavailable)
* Fixed altitude to MSL for network data
* Trace which aircrafts support aircraft parts via network
* Renamed insert_fron push_front (as proposed by Roland)
Status quo / lessons learnt
* On slower PCs jitter is still noticed for interpolated aircraft.
* Running interpolation in an independent process (aka core, not in GUI) reduced load dependencies
=> it seems to make sense to run driver in own thread
* The onGround flag in parts seems clumsy as it required to retrieve parts for position updates
* In interpolation performance really matters
* using split by callsign everywhere
* helper function to insert_front
* revised linear interpolator
* renamed to remoteAircraft
* renamed to container() in providers (gettters are usually copies)
Issues why changes did so long:
* insert in list is not adding in front, but same as push_back (that was confusing)
* naming of values before/after in interpolator was ambigious
* QMap keeps values sorted by key, not arbitrarily
* keep split per callsign map in IInterpolator (so it is available for all interpolators)
* added signals to provider to add split situations / callsigns
* adjustments to airspace / context for those signals
* thread safe access to those from interpolator
* renamed from rendered to remote aircraft as discussed
* adjust samples
* removed no longer required functions in timestampobjectlist
* keep split per callsign map in IInterpolator (so it is available for all interpolators)
* Interpolator using CWorker, so it can run in background
* added signals to provider to add split situations / callsigns
* adjustments to airspace / context for those signals
* thread safe access to those from interpolator
* renamed from rendered to remote aircraft as discussed
* adjust samples
* removed no longer required functions in timestampobjectlist
* changed connectioStatusChanged from uint -> int
* only init QDbusServer for P2P
* changed init order of contexts in runtime
* use "fake" signal to call setComVoiceRooms (remote in GUI)
* added slot to change voice room callsign
* used "org.swift" instead of "net.vatim" (just style)
* used const QString for serviceName
* added correct copyright header (just style)
* support of property index
* used support classes BlackMisc::ITimestampBased, ITimestampObjectList and ICallsignObjectList
* fixed some issues in related aircraft situation class in same step
* consolidated ICoordinateGeodetic (e.g. fixed nested properties)
* shifted common functionality for objects/containers with callsign into interface
* shifted common functionality for objects/containers with geo position into interface
* shifted common functionality for objects/containers with timestamp into interface
* updated corresponding value objects / specialized lists
* adjusted all places where renamed functions are used
* DBus test for CSimulatedAircraft
* Output of metatypes in GUI/core
* Changed output from qDebug() to QTextStream
* Variant test for CSimulatedAircraft
* added functions in component to select COM frequencies
* changed views to contain ObjectType in template
* function to obtain selected objects in view base class
