- remove deprecated actuator_controls[INDEX_FLAPS/SPOILERS/AIRBRAKES]
- use new topic normalized_unsigned_setpoint.msg (with instances flaps_setpoint
and spoilers_setpoint) to pass into control allocation
- remove flaps/spoiler related fields from attitude_setpoint topic
- CA: add possibility to map flaps/spoilers to any control surface
- move flaps/spoiler pitch trimming to CA (previously called DTRIM_FLAPS/SPOILER)
- move manual flaps/spoiler handling from rate to attitude controller
FW Position controller: change how negative switch readings are intepreted
for flaps/spoilers (considered negative as 0).
VTOL: Rework spoiler publishing in hover
- pushlish spoiler_setpoint.msg in the VTOL module if in hover
- also set spoilers to land configuration if in Descend mode
Allocation: add slew rate limit of 0.5 to flaps/spoilers configuration change
Instead of doing the flaps/spoilers slew rate limiting in the FW Position Controller
(which then only is applied in Auto flight), do it consistently over all flight
modes, so also for manual modes.

Previously the condition was based on hard coded height rate estimate and
setpoint values and an altitude error threshold. That showed to be leading
to false positives when the vehicle doesn't tightly follow the altitdue
ramp given by TECS to achieve a new altitude setpoint, and has become
completely infeasibly with the latest TECS rework that leads to non-ramped
altitude setpoint changes in the tecs_status message.
The new check no longer checks the altitude error but only the height rate
instead. It begins to integrate the height rate error once it detects an
uncommanded descend condition (height rate negative while setpoint is
positive). Integral threshold can be tuned by user (VT_QC_HR_ERROR_I).

This failsafe flag is currently used for not allowing to re-transition to FW, as well
as disabling pusher assist in hover. Till now it was only possible to reset it with
a commanded transition to MC, which many ground station interfaces didn't allow
as the system, after a quad-chute, already was in MC mode.
Hereby it is changed to reset when a new transition to FW is triggered (either via
RC switch or MAVLink command). It is the users responsibility to assess the situation
after a quad-chute happened to try to transition to FW again, manually proceed/land
the vehicle in MC, or let it finish the defined behavior after a quad-chute.

* VTOL: take home_position into account for ground clearance
For approximating distance to ground in case there is no valid distance sensor
data, subtract the home position altitude from the local position altitude.

This is to prevent that that data from non-recent publications of the virtual
attitude setpoints are used in the transition code.
It removes the previous implementation where the update_transition_state()
method was only run when both mc and fw virtual att sp where recent, independetly
of whether both are used or not.

- As it is always only used for the vehicle command ack message
- It was a duplicate, hence making it error prone for maintainment
- The uORB message comments were updated to make the relationship with
the MAVLink message / enum definitions clear
The current practice of adding topics to the default set isn't scalable,
as it affects all setups.
By making sure topics are advertised on init, logger can just discard
topics that don't exist. This does not work for all topics, so topics are
specifically marked as optional. It can be extended to more topics later
on though.
This reduces the list of topics by ~35 on a pixracer configured as quad,
and reduces RAM usage by ~1KB.
Tailsitter VTOLs very occasionally gets stuck with zero roll and pitch angle in multicopter mode after
a forward transition command is issued.
This very rare behavior is triggered by the following events:
1> a forward transition is triggered either in auto or manual mode.
2> in the vtol_att_control main loop, if multicopter and fixed wing attitude setpoints are not updated, transition state is not updated
3> the commander changes the vehicle status to transition mode.
4> multicopter pos controller initiated Transition flight task. This results in zero roll and pitch setpoint due to zero acceleration setpoint
5> now vtol_att_control executes and updates the transition state. Specifically, _q_trans_start and _q_trans_sp are set with zero roll and pitch sp
6> tilt is evaluated to be NaN, despite _q_trans_sp being normalized. This happens for 25% of all yaw angles when using float datatype. This can be
verified using the matrix library
7> once tilt is evaluated to be NaN, _q_trans_sp is never updated again and is stuck in this state for ever.
This has been fixed by constraining the cos(tilt) within +1 to -1 range
Further, _q_trans_start and _q_trans_sp are immedietly initialized after a transition event is triggered.
- main motors are the ones which are meant to be used as propulsion in fw mode
- alternate motors are the ones usually meant to be switched off in fw mode

- 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

- this is to prevent vtol_att_control running at absurdly high rates (kilohertz) from every single actuator controls publication from both the multicopter and fixed wing controllers
- I don't really like this solution, but it works for now until there are larger VTOL architectural changes in place
