56cbcb42ee AP_NavEKF2: Add core relative error and errorscore logging in NKF3 packet
TODO : Port lane switching logic from EKF3 to make use of these terms
Since both share the same NKF3 log structure, needed to do this.
Just log 0 as of.

Clarifies use of EK2_RANGE_USE_HGT and EK2_ALT_SOURCE parameters to control range finder use.
Setting EK2_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 EK2_ALT_SOURCE parameter.

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.
