Most subsystems are now created via the subsystem manager using the global
subsystem registrations.
The FGGlobals add_subsystem() and add_new_subsystem() methods have been removed
as the subsystem manager addition and creation function interface now exceeds
the functionality of these helper functions.
Add a bool flag isRoute to flight-plan, and use it to model
routes (which contain VIAs) from plans/legs, which do not.
Default isRoute to false, so most users only see expanded
Vias, and hence something that can be flown directly.
- exclude POIs and some other types from the ident match, to avoid
confusing results
- improve how the search vicinity is computed when inserting a leg,
which is the common case for a route with a destination set. Use
the midpoint of the leg ending at the insert position, as the optimal
search vicinity
- move the waypointFromString code into route.cxx, since it is mostly
independent of a FlightPlan instance
- extend the tests to cover the bug which flagged these issues

Overhaul how transitions are stored in FlightPlan XML, and how
they’re exposed to Nasal. Simplify the Nasal access by making
‘sid_trans’ and ‘star_trans’ writeable.
Extend the unit-tests a lot to cover this, both from C++ and also
from Nasal
As part of this, overhaul the ownership of FlightPlan delegate
factories, to make it safer (use ref-counting of the factories,
and allow the factory to customise delegate clean-up behaviour)
Where the plan does not contain departure / arrival WPs, fire the
corresponding delegate methods after load, to run the selection logic.
Also, add a ‘loaded’ delegate callback, to give delegates a chance to
perform validation and fix-up after all flight-plan loads.
When load a GPX route, run normal departure/arrival airport callbacks
on the delegates. (They are blocked for ‘native’ XML routes to avoid
losing SIDs and STARs)

To support FMS which delete ‘past’ waypoints, add some helpers:
- waypoints can be flagged as hidden, this property is exposed to Nasal
- currentWP() accepts an offset parameter, allowing FlightPlan indexing
to treat the current WP as index 0
- a ‘numRemainingWaypoints()’ function on flightPlan in Nasal, again
to range how many waypoints are left, starting from the current WP
Add some basic tests of these new features to the route-manager tests.
Add some tests for the default GPS / route-manager handling of
DISCON in flight-plans. Especially check behaviour when sequencing
a DISCON, and resuming with a Direct-to after one.
This requires a corresponding FGData update to the default GPS Nasal.
Ensure changes from Nasal are picked up by delegates (such as GPS) when
they are made. Add a route-manager test which sets and exits a hold
using Nasal.
As part of this, update the test API to make it easy to run Nasal from
a test.
GPS now lets the delegate handle the sequencing behaviour, by
setting a new config property. The default GPS delegate (in Nasal)
now sets this property.
This requires a corresponding FGData update.
