* 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
* added getAirlineIcaoCodeForUniqueDesignatorOrDefault and getAirlineIcaoCodeForUniqueIataCodeOrDefault from reader/web data services
* rearranged order of functions in ICAO reader
* added some more functions like "containsXX" in reader
* unified member access (this->m_xy => m_xy)
* set object name of readers
* waitForSharedInfoObjectsThenRead (not just waiting, also reading afterwards)
* in case the internet provider is down, this is not detected
* extended test to detect if access is possible
* in case of downtime this indicated in status component
* Log when VATSIM status file has been read
* fix: read VATSIM status file after initReaders completes
* some private slots -> normal private functions
* removed copy/paste error illegalIcaoCodes
follow up of Ref T105
* use doWorkCheck
* relaxed doWorkCheck in unit tests
* removed isShuttingDown, gracefulShutdown
* set timer object name (in case something is wrong, we might see the name in the log)
* no longer using header timestamps, removed functions
* renamed functions to distinguish shared/DB info data
* added 2nd reader m_sharedInfoDataReader
This will replace http header file timestamps
* read function in info reader has retrieval mode flag, unused parameters removed
* waitForDbInfoObjects/getDbInfoDataReader (added "Db"), there will be a 2nd reader
* CWebReaderFlags::DbInfoDataReader (added "Db")
* removed ps_read, only read (public)
* trigger other operations directly when data have been read (do not wait for "all data read")
* avoid retriggering for no reason
* new entity flag for all data req. for model matching
* split JsonDatastoreResponse in subclass HeaderResponse
* support for request newtwork request duration ("started") in application
* removed ps_setupChanged because it was unused
* utility function if web data are already available
* moved setOwnAircraftModel as reverseLookupAndUpdateOwnAircraftModel to CSimulatorCommon
* reverseLookupAndUpdateOwnAircraftModel also handles async lookup when data are not yet available
* removed context ps_allSwiftWebDataRead reverse lookup, done in CSimulatorCommon now
* added amit functions in readers
* cacheHasChanged functions (needed because data of caches are loaded in background)
* pinned small caches
* CDatabaseReader::readInBackgroundThread uses admitCaches now
* use triggerReloadFromDb
* improved documentation
MS report:
`AllDbEntities` should be `AllDbEntitiesNoInfoObjects` in `CDataInfoAreaComponent::requestUpdateOfAllDbData`?
Otherwise it triggers assert `!whatToRead.testFlag(CEntityFlags::InfoObjectEntity)` in `CWebDataServices::triggerRead`.
* added signatures for completer string (when send via context size matters)
* support of all instaled models in completer
* added BLACKMISC_EXPORT in model cache classes
* Ignore mode, not all applications need to load everything (mapping tool no airports)
* removed signal in airport reader which is already in base class
* added "virtual" keyword
* fixed another syncronize typo
* added allDbEntiiesUsed() to also reflect the config (ignore flag)
* ensure allSwiftDbData are signaled correctly even with ignore flag
* removed workaround in web data services
* removed convertFromDatabaseJson functions, not needed
* changed to use the correct static fromDatabaseJson functions
* fixed prefixes
* load correct Country object by loading it as nested object
* key and timestamp was missing in CAirport tuple metadata
