Andrew Tridgell 1b6c329de5 SITL: use NaN for invalid rangefinder data 
needed to cope properly with terrain errors leading to negative
rangefinder data
 2023-08-24 13:06:40 +10:00
Andy Piper 3224cf19a8 SITL: remove unused variables 2023-07-13 11:02:40 +10:00
Andrew Tridgell 7a4483b091 SITL: new XPlane backend 
this makes use of DRefs to greatly improve XPlane support. It only
supports XPlane 11 and later

The key change is the use of a JSON file to map ArduPilot output
channels to DataRefs, and map raw joystick inputs to RC inputs

this gets rid of the awful throttle hack handling, and allows for
control of a much wider range of aircraft

Andrew Tridgell a0af08a3aa SITL switched to motor_mask for which actuators are motors 
this allows for any output to be an ESC, which allows for proper
simulation of quadplanes with ESCs on outputs 5-8 or 9-12, for testing
notch filtering

Peter Barker 3cf7091525 SITL: make parsing of json files dependent on PICOJSON

platforms

Peter Barker 0661a27400 SITL: ensure st.size is valid when loading model json 
Before this patch st.size is undefined when we use it to create a buffer
on the stack - probably not a good thing.
