6989a28bfc AP_NavEKF3: allow alt from other sources when using ExtNav 
also allows using ExtNav alt when not using it for XY position
removes redundant and incorrect setting of activeHgtSource from ExtNav
which was always being overwritten by the correct value later in selectHeightForFusion

8a4b0f858a AP_NavEKF3: reset body mag variances at key points 
we need to reset the body mag variances if we change sensors or if we
are starting 3D fusion. When not doing 3D fusion we zero the
variances, so they must be initialised again when we restart
fusion. This fixes a bug in handling the variances on a 2nd flight

1f21d72c79 AP_NavEKF3: fixed init of earth state mag variances

2bc7d17e7a AP_NavEKF3: improved core comparison to check alignment 
this adds coreBetterScore() which takes account of tilt and yaw
alignment when comparing cores for lane switching

this ensures we don't switch to a lane that is unaligned due to the
zero error score for unaligned lanes

edc3709653 AP_NavEKF3: implement sensor affinity using EK3_AFFINITY parameter 
this allows the EKF core index to be used to select a GPS/baro/mag
instance. This is an alternative to GPS blending that allows EKF lane
switching to be used to select the right combination of GPS and IMU
add logging to XKFS message

d7edc946b6 AP_NavEKF3: Relative Error based Lane-Switching 
Improvments to the lane selection logic, we accumulate error for each
EKF lane relative to the primary for a more robust core selection
