Letting the autopilot set the heading during landing while the pilot is
nudging the vehile leads to a weird UX as the vehicle would make a turn
instead of translating.
With this modification, the initial land heading is immediately overridden when the pilot
begins to adjust the drone's position, providing the sensation of full control.
* Yawsticks on gimbal, vehicle follows gimbal in slowmode, once vehicle has taken off
* Increase queue length to avoid automatically unadvertise queued publications with queue length 1
* Improve readability

This fixes a race condition when switching from a flight mode that is
not a flight task (e.g.: stabilized). In this case, the reset counters
were initialized to 0 and deltas were applied to the first setpoints if
the EKF had any of its reset counters different from 0.
* fix max-hagl restriction to position/altitude control
* max hagl vel restriction in ManAcc position mode
* use interpolate func, change naming
* simplyfied vertical vel limitation
* move velocity-constraint adjustment to StickAccelXY
The default implementation for multicopter Position mode is FlightTaskManualAcceleration.
The last missing piece was support for CollisionPrevention in this implementation.
Instead of tracking a fixed deceleration setpoint during the backtransition we added here position feedback,
such that the vehicle comes to a stop latest at the current position setpoint. This reduces the risk of
overshooting the landing point.
If no position feedback/position setpoint is present the old logic still applies.
It further moves the braking controller to the FlightTaskTransition instad of doing it in
the VTOL attitude mode.
* vtol_type: added position feedback to backward transition
* FlgithTaskTransition: refactored backtransition deceleration/pitch setpoint computation
* FlightTaskTransition: minor improvements
* FlightTaskTransition: use .dot() consistently and remove unnecessary comments

* PositionSetpoint: remove yaw_valid field
* Navigator: set yaw setpoint to NAN for Takeoff
Don't set a yaw setpoint for takeoff, as Navigator doesn't handle the yaw reset.
The yaw setpoint generation is handled by FlightTaskAuto.
* PositionSetpoint.msg: remove disable_weather_vane and instead only use the yaw field
Strictly follow the concept that if the position_setpoint.yaw is set, then
follow it the controller, and otherwise let the controller set it as it
thinks it's best.
* Navigator: remove logic that sets yaw to be accepted in TAKEOFF
No longer needed as during Takeoff we anyway don't set a yaw setpoint.
* PositionSetpoint.msg: remove yawspeed_valid
* PositionSetpoint.msg: remove yawspeed
* Navigator: set yaw setpoint to NAN instead of current
In set_takeoff and set_land_item, as well as for VTOL transition.
The flight tasks then set the yaw corresponding to the current yaw.
* Navigator: change get_yaw_acceptance into a bool
* PositionSetpoint.msg: improve comment for yaw
* MissionBlock: remove unnecessary code from set_vtol_transition_item
* Navigator: clean up calculate_breaking_stop(), set yaw to NAN
* Navigator: set yaw to NAN in variouls places where not specifc setpoint is desired
* Navigator: set yaw to NAN in reset_position_setpoint()

As discussed in the maintainer call we should adhere to the
parameter naming scheme that makes it clear what vehicle type the
configuration is good for.
by only applying the sqrt linear drag when brakeing.
It was originally not done this way to avoid discontinuities and
the exact speed bewlo 1m/s didn't matter. With the position slow mode
the exact slow speeds now matter. And the discontinuities are avoided by
reusing the brake boost filter.
