354b551ef0 AP_NavEKF3: Handle repeated FW flight without magnetometer 
The EKF can build up large yaw errors on ground so it is safer to stop using GPS and re-align after launch as per first launch.

906731222d AP_NavEKF3: Fix range aid switching logic 
Clarifies use of EK3_RANGE_USE_HGT and EK3_ALT_SOURCE parameters to control range finder use.
Setting EK3_RNG_USE_HGT to a positive number to enable automatic switching between the primary height source (baro or GPS) and range finder should be disabled if any primary height source other than Baro or GPS is selected via the EK3_ALT_SOURCE parameter.

318811210f AP_NavEKF3: Don't perform emergency yaw reset unless commanded externally 
This limits the use of the reset to situations where it is a last ditch resort before a lane switch and failsafe.
This will limit false positives for general deployment, but still provide protection from fly-aways at the cost of some increase in reaction time.
