The acceleration setpoint gets implicitly inherited from the altitude
flight task since #14212. This feed-forward adds an unwanted
acceleration when the right stick is deflected. Instead I'm using it
to command the expected centripetal acceleration when flying
in a circle for better orbit tracking.
For the RC controlled yaw behaviour, we do a yaw setpoint according to
the stick expo. The uncontrolled yaw behaviour behaves undefined.
Switching between yaw behaviours makes the drone stand still for a
moment, which probably can be improved.
* FlightTask: Fix ekf2 reset race condition during task switch
During a loss of GPS data when using GPS as primary height source,
the height is reset to baro and the local position gets invalid at the
same time. This triggers a switch to altitude flight task and a setpoint
reset.
This combination of events had the effect to ignore the height reset,
the large sudden height error could create an abrupt change of altitude
or even a crash.
The ekf2 reset is now done at the beginning of each update call.
