As some tiltrotor systems need a certain tilt angle of their motors in oder to spin up freely,
this commit introduces an additional parameter VT_TILT_SPINUP and sets the motor tilt to
this value if disarmed or within 1s since arming.

The spinup consists of 2 phases:
    1st phase fixed tilt (duration hardcoded to 1s)
    2nd phase transition from spinup tilt to multicopter tilt (hardcoded to 0.5s)

Before this check we were free to fly outside of a geofence with a goto
command. With this check we ignore the command if the location of the goto
is outside the fence. If this is the case we send back a mavlink warning to
the ground station.

This can only happen if the vehicle is executing a go to.

This is a corner case that happens when the user wants to command an
altitude change just after a takeoff. Takeoff doesn't set the current
lat and lon therefore the user had to change altitude twice to get it working.
The first time to set the current lat and lon and the second time to
actually change altitude.

 - remove leftover Start()
 - remove "reset" from command line (stop + start is sufficient)

Non-functional change, just change the sign in the correct place to
avoid further confusion.

Therefore, let's try with v2-preview.

When this triggered it actually just kept printing
"floating point exception" and never recovered. By removing this we can
at least catch it with a core dump, in CI as well as locally.

The InvenSense icm20608g and icm20689 don't have a FIFO watermark interrupt, but they do have a data ready interrupt and the ability to get the current FIFO count in the same large transfer as the actual FIFO data. So instead of manually checking the FIFO count before every transfer (costs ~ 1-3% cpu) we trust the data ready counts, verify things are in sync after the large transfer (fifo count + fifo contents), and force a manual check before the next transfer if necessary.

As a precaution this change lowers the threshold for forcing a manual FIFO count check before the large transfer. Forcing the check if out of sync by 2 (or more) samples makes sense because we always do transfers in multiples of 2 (gyro samples per accel).

The other small cosmetic changes are keeping the icm20608g and icm20689 in sync (they're nearly identical).

…d instead of samples

 - fixes #14303

 - increase stack sizes to run cleanly under stackcheck
     - this is likely overkill for most boards, but using stackcheck to set our minimum ensures we have a very safe margin on regular builds and it's something we can currently afford
 - remove holybro_durandal-v1_stackcheck from test rack (there's only one unit)

 - this was interesting to monitor, but slows down the entire build with only one pixracer on the test rack

 - gives an idea of the cost of copying a large message

 - board has either an icm20602 or icm20608g, not both
 - probe all typical externally compasses

on a fmu-v2 where VTOL is no longer included.
