A setpoint of type IDLE can be published by Navigator without a valid position,
and should be handled in the auto function in FW_POSCTRL_MODE_AUTO. If it wouldn't be
handled there the controller would switch to mode FW_POSCTRL_MODE_OTHER, in which case
no attitude setpoint is published and the lower controllers would be stuck with the
last published value (incl. thrust).

when we're in a takeoff situation, we only want to adapt the airspeed to

During transition to FF, only allow update thrust axis up to 45° as with a high tilt angle
the effectiveness of the thrust axis in z is apporaching 0, and by that is increasing
the motor output to max.
Transition to HF: disable thrust axis tilting, and assume motors are vertical. This is to avoid
a thrust spike when the transition is initiated (as then the tilt is fully forward).

Some system are able to dead-reckon for a while after losing GPS or
other sources providing positional feedback. If the estimated position
error grows above the failsafe threshold, the system enters a failsafe
mode. As the position error estimate is growing linerly over time, and
it is recommended to take action before entering the failsafe, we here
warn the user about the imminent failsafe and propose to take manual
control.

Instead of hard-coding the tilting duration (from FW to MC tilt),
expose it as a parameter (VT_BT_TILT_DUR). The default is the same
as the hard-coded value previously (1s).
Slower tilting mechanisms need a higher value here, while for smaller
ones a too high value results in unnecessary delays till the motors
are in hover configuration.

This affects how soon after a backtransition the vehicle has the
full hover controller running again. Specifically it reduces the
duration of the ramp down of the motors prior to tilting them.

Transitions in Stabilized mode are done manually, the pilot controls the pitch angle
and if it's above the threshold the transition is declared finished (plus airspeed
check for front transition). Thus we can't have fixed thresholds but need to link
them to the actual max pitch angle in Stabilized mode.

We currently fuse 0 as airspeed rate measurement, and thus simply low-pass
filter the airspeed measurements. Testing has shown that the current default
on the airspeed rate measurement noise is set to low, and thus the airspeed
mesurement is filtered too much.

Once passed the transition and in FW mode, it takes some ms unitl the FW att sp is updated

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).
