NavData: don't load XML extension files from unsuitable scenery paths
Add a 'scenery_path' field to the 'airport' table of the SQLite NavDataCache database. For each airport, this field indicates the scenery realpath() that contributed the apt.dat file for the airport (as an exception, for airports whose apt.dat file is $FG_ROOT/Airports/apt.dat.gz, the path thus stored is for now $FG_ROOT, which is technically not a scenery path). This path is then made available via FGAirport::sceneryPath(), which allows us to implement the following change (in this commit): A) The lookup of *.procedures.xml is unchanged. B) For other XML extension files (groundnet, ils, runway_rename, threshold, twr): - The search performed by XMLLoader::findAirportData() through globals->get_fg_scenery() stops immediately after the scenery path p that contributed the apt.dat file for the airport. - Paths that come earlier than p in globals->get_fg_scenery() order may contain XML extension files that will *override* sibling files that might exist in p (as was already the case before this commit). The rationale behind this change is that we don't want a custom scenery with good data in its NavData folder regarding airport FOO to get "ruined" by files such as FOO.threshold.xml present in the TerraSync directory---which is assumed to come later in globals->get_fg_scenery() order. *.procedures.xml files are excluded from the change because there is a widespread use of a huge set of procedure files for the whole world; if airport FOO in a custom scenery has no procedure files, we do want to let FlightGear find FOO.procedures.xml inside the scenery path containing the huge dataset (which should come *after* custom sceneries in globals->get_fg_scenery() order so as to give these custom sceneries the option to provide better *.procedures.xml files and have them take precedence over less specialized sources such as the huge dataset).
