Here is a patch interested people can test before I reread it and commit
(David?). I passed a null SGPath as proposed above (this causes
XMLLoader::findAirportData() to perform “full $FG_SCENERY traversal” for
the corresponding airport, as in case A below). The main “user-visible”
change is as follows:

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
   $FG_SCENERY stops after the scenery path p that contributed the
   apt.dat file for the airport.

 - Paths that come earlier than p in $FG_SCENERY may contain XML
   extension files that will *override* sibling files that might exist
   in p. This was an option I already mentioned; it's easy to change if
   there is consensus to only consider XML extension files from scenery
   path p.
