b9a5794671 AP_NavEKF3: ensure that both AMSL and relative alt are correct after a reset 
this forces the EKF origin to the GPS alt on a height datum reset if
we have GPS lock. If we don't do this then the reported AMSL alt will
drift over time away from the GPS alt when we reset while on the
ground

209bca162c AP_NavEKF3: added inactive bias learning 
this allows for biases on inactive IMUs to be learned so that an IMU
switch within an EKF lane does not cause a jump in the IMU data

5151416080 AP_NavEKF3: force first EKF lane when disarmed 
this ensures we consistently fly with EKF lane1 if it is healthy at
the point we arm. Otherwise the choice of lane will be a lottery.

This is important as many systems have quite different filtering and
vibration characteristics on their different IMUs. We by default
enable fast sampling only on the first IMU for example, which means
the 2nd and 3rd IMUs are more vulnerable to high freq causing
aliasing.

e4f6ffe719 AP_NavEKF3: fixed bug in EKF lane selection 
this fixes an issue in selecting the best lane to change to when we
have 3 or more EKF cores. The bug is that if the current lane is
unhealthy it would always choose the last healthy lane instead of
choosing the lane with the lowest score

39ffef1f08 AP_NavEKF3: fixed EKF compass switching 
when we had 3 compasses the lack of the 'break' meant when we switched
compass in flight we would always switch back instantly to the one
that we had just rejected.

560f17a570 AP_NavEKF3: use union to alias array and struct access to states 
This avoids creating two pointers of different types to the same memory.

Having two pointers to the same memory can lead to the compiler
optimising code such that a write to one pointer is rearranged to be
either before or after a read from the other pointer depending on
which is deemed faster - not a good outcome.
