af19fea268 AP_NavEKF2: Fix 3-axis mag fusion per axis error handling 
Ensure that if fusion checks for an axis fails, fusion will not be perfomred for all axes.

c94de61e29 AP_NavEKF2: 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.

abc821ad36 AP_NavEKF2: Split GSF yaw estimator processing 
Separate prediction and correction steps are required to provide an up to date yaw estimate using IMU prediction before it may be required by SelectMagFusion() whilst still doing the velocity update after GPS data haw been pulled from the buffer by SelectVelPosFusion()

de0040ad69 AP_NavEKF2: Enable use of EKF-GSF yaw estimate 
Enables the yaw to be reset in flight to a value estimated from a specialised yaw estimator. This allows faster recovery if taking off with a bad magnetometer and also allows yaw alignment and GPS use to commence in-air when operating without any yaw sensing.

9030590a88 AP_NavEKF2: fixed use of antenna position when switching GPS primary 
when GPS primary switches we were using a position which had not been
corrected for antenna offset. This was used for calculating the reset
for sensor change.

This fixes that (trivial fix) and also fixes a similar issue on
position reset
