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.
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.
AP_NavEKF2: Add missing accesor functions for default airspeed
this moves intermediate variables from being per-core to being common
between cores. This saves memory on systems with more than one core by
avoiding allocating this memory on every core.
This is an alternative to #11717 which moves memory onto the stack. It
doesn't save as much memory as #11717, but avoids creating large stack
frames

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.
