* update ecl to latest

* EKF2_GPS_DELAY change default 200ms -> 110ms

 - 110msec is more representative of what most users are flying

* EKF2_ASP_DELAY change default 200ms -> 100ms

The EKF is relatively insensitive to airspeed sensor delays and the effective delay is installation specific, so it has been set to a value that does not cause the data buffers to be longer than is required to accomodate GPS delays.

* Drone does not change orientation while in LOITER mode if MIS_YAWMODE=0

* Fix code style

* Some more code style fixes

* Format checks passed

 - move controllib_test under controllib

Make the declarations of the  variables "roll_sp, pitch_sp, yaw_sp, throttle_sp," in the main loop more readable.

This allows the ground control station or any other communication partner to query the supported versions. The key aspect is to send the response in MAVLink 2 framing to test the link with a MAVLink 2 framed message.

It's obsolete since we removed the mavlink log file

The MAVLink app was logging the status to a file on the SD card, however, this has been integrated into the ulog format since. Having these in multiple locations is unnecessarily confusing to the user and induces load to the system.
