The MAVLink specs for CreateFile in MAVLink FTP were updated on Dec 23, 2020 (today) with a behavior change to truncate a file if it already existed, following the UNIX standard behavior: https://pubs.opengroup.org/onlinepubs/9699919799/functions/creat.html. This change is tracking that spec change. While it is a functional change, the limited usage of the FTP protocol and the fact that implementations should not rely on error states to determine wether to truncate a file or not makes this a viable change.
Without range finder, the validity flag goes to false quite quickly and
if can be that a vehicle never starts HTE is the takeoff is too slow.
In this specific context of takeoff detection, since
the exact value is not important, we can safely ignore the validity flag.
the _landed flag only is not enough to tell if the drone is still touching
the ground, so an additional check based on the altitude AGL is required.
to have this in_air detection correctly updated, the module needs to be
scheduled on the vehicle_local_position message as no setpoint is
produced in non-assisted modes.
- updating the global position validity should happen regardless of
being in manual position control mode with only optical flow
- condition_global_position_valid needs to be accurate to adjudicate
main state changes (eg going into AUTO MISSION)
- split out switches from manual_control_setpoint into new message manual_control_switches
- manual_control_switches published at minimal rate (~ 1 Hz) or immediately on change
- simple switch debounce in rc_update (2 consecutive identical decodes required)
- manual_control_switches logged at full rate rather than sampled at (5-10% of messages logged)
- manual_control_setpoint publish at minimal rate unless changing
- commander handle landing gear switch for manual modes
- processing of mode_slot and mode_switch is now split so we only do one or the other (not both)
- a future step will be to finally drop mode_switch and accompanying switches entirely

- reset IMU bias on calibration change (only works with multi-ekf)
- standardize PX4_INFO/PX4_WARN/PX4_ERR output for multi-ekf with instance number
- https://github.com/PX4/PX4-ECL/pull/924
- depending on the particular sensor configuration and startup timing we were getting an initial sensor_selection publication without valid accel & gyro device ids (only applies to Multi-EKF)
- fix faulty accel and gyro device ids
- initialize unused test ratio fields to NAN for logging clarity
