5s is a more reasobale time for tailsitters, which rely differently on this param
than other VTOL types. Tailsitters will ramp the pitch up withing this time,
while for other VTOLS types its only the max transitiont time.

A default of 10s makes more sense compared to the old 4s, as this is only the
max time of a back transition and it's also decleared completed if the
speed drops below the hover cruising speed (MPC_XY_CRUISE).

There have been substantial TECS changes lately, and the config files
for custom VTOLs have not been updated since a long time. I would thus
rather use the default TECS gains for lightly maintained configs.

The attitude frame is wrong for tailsitters doing side slip fusion for wind estimation.
It doesn't take into account that the frames is 90deg tilted in FW flight.

MIS_LTRMIN_ALt was used to limit the go-to altitude of a LOITER_TO_ALT (not the exit altitude,
but the altitude that the vehicle went to to fly to WP), and during landing abort to climb to
at least this altitude. The min entry altitude of LOITER_TO_ALT I remove with this commit, while
for the min alt during abort I added the new parameter MIS_LND_ABRT_ALT.

* Enable motor controls for fixed wing mode in tailsitters
This commit enable motor controls in fixed wing mode for tailsitters
This is needed for enabling quad tailsitters
* VTOL: differential thrust in FW: adapt params to be generic for all axes
Until now only suppoted on yaw axis. Not to be supported also on Roll and Pitch.
- VT_FW_DIFTHR_EN: make bitmask for all three axes independently. First bit is Yaw,
sucht that existing meaning of VT_FW_DIFTHR_EN doesn't change.
- VT_FW_DIFTHR_SC: rename to VT_FW_DIFTHR_S_Y and add same params for roll (_R) and
pitch (_P).

When hitting zero thrust by stick there is 0 torque authority
without airmode. So 0% minimum manual thrust should never be the default
without airmode.
Also remove the legacy "range aid" than can be achieved by setting the
height reference to range finder and the range finder control parameter
to "conditional".
Conditional range aiding cal also be set when the height reference isn't
the range finder. This prevents the ratchetting effect due to switching
between references.
This is the control surface type for airframes that have only a
single aileron servo or have the ailerons on a single output channel.

I think most vehicle can safely decend with at least 1.5m/s, and having this
value too low makes Descents/Landings/RTLs unnecessary long.

- landing slope/curve library removed
- flare curve removed (the position setpoints will not be tracked during a flare, and were being ignored by open-loop maneuvers anyway)
- flare curve replaced by simply commanding a constant glide slope to the ground from the approach entrance, and commanding a sink rate once below flaring alt
- flare is now time-to-touchdown -based to account for differing descent rates (e.g. due to wind)
- flare pitch limits and height rate commands are ramped in from the previous iteration's values at flare onset to avoid jumpy commands
- TECS controls all aspects of the auto landing airspeed and altitude/height rate, and is only constrained by pitch and throttle limits (lessening unintuitive open loop manuever overrides)
- throttle is killed on flare
- flare is the singular point of no return during landing
- lateral manual nudging of the touchdown point is configurable via parameter, allowing the operator to nudge (via remote) either the touchdown point itself (adjusting approach vector) or shifting the entire approach path to the left or right. this helps when GCS map or GNSS uncertainties set the aircraft on a slightly offset approach"
- all sources of optical flow publish sensor_optical_flow
- sensor_optical_flow is aggregated by the sensors module, aligned with integrated gyro, and published as vehicle_optical_flow

rename follow_me_status to follow_target_status
enable follow_target_estimator on skynode
implement the responsiveness parameter:
The responsiveness parameter should behave similarly to the previous
follow-me implementation in navigator. The difference here is that
there are now two separate gains for position and velocity fusion.
The previous implemenation in navigator had no velocity fusion.
Allow follow-me to be flown without RC
SITL tests for follow-me flight task
This includes:
- Testing the setting for the follow-me angle
- Testing that streaming position only or position
and velocity measurements both work
- Testing that RC override works
Most of these tests are done with a simulated model
of a point object that moves on a straight line. So
nothing too spectacular. But it makes the test checks
much easier.
Since the estimator for the target actually checks new
measurements and compares them to old ones, I also added
random gausian noise to the measurements with a fixed seed
for deterministic randomness. So repeated runs produce
exactly the same results over and over.
Half of the angles are still missing in MAVSDK. Need to create
an upstream PR to add center left/right and rear left/right options.
These and the corresponding SITL tests need to be implemented
later.
sitl: Increase position tolerance during follow-me
Astro seems to barely exceed the current tolerance (4.3 !< 4.0)
causing CI to fail. The point of the CI test is not to check
the accuracy of the flight behaviour, but only the fact that the
drone is doing the expected thing. So the exact value of this
tolerance is not really important.
follow-me: gimbal control in follow-me
follow-me: create sub-routines in flight task class
follow-me: use ground-dist for emergency ascent
dist_bottom is only defined when a ground facing distance sensor exist.
It's therefore better to use dist_ground instead, which has the distance
to the home altitude if no distance sensor is available.
As a consequence it will only be possible to use follow-me in a valley
when the drone has a distance sensor.
follow-me: point gimbal to the ground in 2D mode
follow-me: another fuzzy msg handling for the estimator
follow-me: bugfix in acceleration saturation limit
follow-me: parameter for filter delay compensation
mantis: dont use flow for terrain estimation
follow-me: default responsiveness 0.5 -> 0.1
0.5 is way too jerky in real and simulated tests.
flight_task: clarify comments for bottom distance
follow-me: minor comment improvement
follow-me: [debug] log emergency_ascent
follow-me: [debug] log gimbal pitch
follow-me: [debug] status values for follow-me estimator
follow-me: setting for gimbal tracking mode
follow-me: release gimbal control at destruction

Without this, uavcan creates MixingOutput classes which then create
empty actuator_outputs publications. This then prevents the motor
output in HITL to be forwarded to the simulator via mavlink.
