Andrew Tridgell 68a43b3c79 AP_NavEKF: getYawData also provides number of clipping models 
In the case of the compass calibrator we do not want to use the GSF
result if any model is degenerate.  We've had a compass calibrate in
flight 180-degrees out from what it should have.

Andrew Tridgell 3235747ef8 AP_NavEKF: allow for double EKF build 2021-07-10 07:20:41 +10:00
Paul Riseborough afb31bc4f5 AP_NavEKF: Add underflow protection to yaw GSF weight normalisation 
This improves protection against a condition where if all yaw hypothesis filers have very large innovations, the weights of Gaussian densities can underflow leading to failure of the weights to converge.

Paul Riseborough 4a743a3827 AP_NavEKF: Remove unnecessary reset operations and class variables 
The setting of EKF state variances is only required when commencing or recommencing velocity fusion.
The function that resets the EKF and GSF class variables has been renamed to be more consistent with its function.
