James Turner 63fe5237c6 Improve interaction of —parkpos and repositioning 
Re-work how position-init and ATC-manager work together to do
parking assignment and fallback (when the parking is unavailable).
Improve the logic for the reposition case, and teach ATC-manager about
reposition explicitly.

When the parking is unavailable, explicitly fall back to best-runway
selection in finalizePosition.

Add many additional position-init tests, to cover all of this.
