- saves a small amount of work for the ekf2 selector in multi-EKF mode (visual_odometry_aligned now ignored)
- helps to distinguish the origin/purpose from vehicle_odometry and vehicle_visual_odometry
In the predition step, the process variance was erroneously
multiplied by dt instead of dt^2. The default values are adjusted
accordingly to keep the same tuning for the default loop rate of 50Hz
- ekf2 can now run in multi-instance mode (currently up to 9 instances)
- in multi mode all estimates are published to alternate topics (eg estimator_attitude instead of vehicle_attitude)
- new ekf2 selector runs in multi-instance mode to monitor and compare all instances, selecting a primary (eg N x estimator_attitude => vehicle_attitude)
- sensors module accel & gyro inconsistency checks are now relative to the mean of all instances, rather than the current primary (when active ekf2 selector is responsible for choosing primary accel & gyro)
- existing consumers of estimator_status must check estimator_selector_status to select current primary instance status
- ekf2 single instance mode is still fully supported and the default

- add new parameter `IMU_GYRO_FFT_EN` to start
- add 75% overlap in buffer to increase FFT update rate
- space out FFT calls (no more than 1 per cycle)
- increase `IMU_GYRO_FFT_MIN` default
- decrease main stack usage
This is done to prevent yawing 180 degrees when switching
to hold mode with high velocity and the overshoot causing a 180°
yaw turn.
The yaw is unlocked on waypoint updates and the yaw
setpoint generation had to be put at the end because otherwise the
first yaw calculation is with the old waypoint and immediately
locks again.
benefits:
- read & validate product name
- sensor configuration with the output we want (raw distance data)
- get signal quality

Other Lightware sensors can easily be moved over to that as well.
- mavlink messages DEBUG/DEBUG_FLOAT_ARRAY/DEBUG_VECT/NAMED_VALUE_FLOAT move to separate stream headers and don't include if CONSTRAINED_FLASH
- mavlink receiver DEBUG/DEBUG_FLOAT_ARRAY/DEBUG_VECT/NAMED_VALUE_FLOAT handling excluded if CONSTRAINED_FLASH
- msg: skip debug_array.msg, debug_key_value.msg, debug_value.msg, debug_vect.msg if CONSTRAINED_FLASH
px4_add_library adds uorb dependencies, which since cf26f24387d added libm.
This in turn led to build failures for px4_io-v2 in the form of:
__aeabi_f2d' wf_sqrt.c:(.text.sqrtf+0x54): undefined reference to
__aeabi_ddiv'
