Don't use ADSB messages with undefined fields in navigator

 - fixes #8903

this will be used by the ekf2 at some point

Adding aerofc baudrate 921600 into the list

This avoids assembling the header and payload on the receiver side

The NuttX config variable CONFIG_TASK_NAME_SIZE does not include the
null terminator byte, thus the buffer needs to be longer by 1 byte.

- simulated tailsitter needs a virtual elevator since we cannot simulate
elevons yet (liftDrag plugin does not model longitudinal moment Cm)

This change allows the LIS3MDL based GPS magnetometers to autostart on the mRo x2.1.

This was wrong, instead of warning at 2/3 of the max distance as
mentioned in the comment, we would start to warn at 3/2 of the distance
which would then never actually happen.

Update maintenance team duties according to latest discussions on dev call.

This causes severe oscillations in aggressive maneuvers with high tilt
angles. It's an issue on VTOL's too, but the modification is specifically
for VTOL's and VTOL's typically do not fly with such high tilt angles
(>50 deg).
