afcdbd3158 Overhaul the ground-net / parking code.
Use the nav-data-cache to cache groundnet information, including
parking positions and the taxi-node graph.

b1ff365a8f Make FGTaxiNode and FGParking inherit FGPositioned.
In preparation for caching the groundnet in the NavCache, make taxi-nodes and parkings inherit from FGPositioned. As part of this, make them heap (as opposed to value) classes, disable their copy-constructors, remove many mutating operations, and give them real constructors.

9b900e9430 Implement a persistent cache for navigation data.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).

Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).

ffbb0a0e5d Sink position-init code into its own file.
Separate other init functions from position init, since they are unrelated, and made fg_init.cxx very complex. Next step will be brining some sanity to the position init logic :)
