updated VT_FW_MOT_OFFID

Replaced individual elevator and aileron into "elevons"

-closes #5862

This makes the onboard check consistent with hmc5883_bus_option
initialization. If the current bus is the onboard bus, return !external.

It fixes the onboard mag (HMC5883) for AeroFC. Its priority is now 100,
previously it was 255, so that if an external mag is attached, it will be
preferred.

This reverts commit 126172d7.

This commit is going in the wrong direction: it's actually the same as
it was before, but allows changing the autostart configuration to
something other than 4070, which means people could wrongly assume it
would work in other configurations.

Needed for log streaming

- fixed a bug where tilt compensation was done also when the horizontal
velocity was controlled. This is not needed because in this case
the controller outputs a 3D thrust vector.

* Fixes for sitl gazebo ground truth.

* Switch ekf2 to new logging module for sitl.

Preflight checks: made sure pre-flight check results are always reported first thing on the console and always on new or re-established telemetry links AFTER waiting for the hotplug timeout
(leads to double publishing on the console when a new link is established, but this is the best compromise between fixing and completely restructuring)

This update is needed after changes in
https://github.com/ATLFlight/cross_toolchain/pull/10.
