APX4 3.2.14
General Improvements
Commander Failsafe: Never override a user intended Termination. Fixes: system switches out of Termination during a failsafe event.
Example: The user sends a termination command to the vehicle (e.g. by pressing the Shutdown button in the AMC Emergency Actions) and then switches off the remote control station before the vehicle is disarmed. Without this fix the drone will execute the "manual control loss" failsafe (by default: Return to Launch) and spin up the motors again. With this fix a switch to Termination is not reversible, the vehicle cannot switch to another mode and has to be rebooted to be flown again.
Navigator: RTL type reverse: during last stage of landing, set next waypoint to invalid. Fixes: Vehicle oscillates horizontally while in landing during a RTL type reverse (RTL_TYPE=2 and no mission landing).
EKF2: Initialize global position from GNSS position when no global position measurement exists but GNSS velocity is active. Fixes: Position estimation not initialized in these cases.
Increase stack size of UAVCAN workqueue. Fixes: Removes "Low on stack" warnings.
