Plane supports being armed, in takeoff logic and not spinning the motor
until the moment the safety button has been pressed. Unfortunately
because the safety button is required to be pressed for soft arming this
results in the plane updating home position while the user moves the
vehicle or is holding it to throw the vehicle which will can result in
several meters of altitude error from where the user expected home to
be.
Because the normal approach to plane is to have activated the safety
button before arming the aircraft this is not expected to be a behaviour
change for most users, but an improvement for people who use the button
to initiate a takeoff.
when Q_RTL_MODE=1 in a quadplane use RTL_RADIUS as the distance to
switch to QRTL mode. We navigate to the destination using direct
waypoint navigation instead of using a loiter circle.
some people connect USB to allow connections from a companion
computer. The arming check is sufficient to prevent unwanted battery
failsafes when bench testing
the nav controller can think we have already reached the loiter target
if we were last in a LOITER when we switch to RTL. In that case it
would switch to QRTL immediately

this allows the user to control tailsitters either in body frame (like
a plane) or in earth frame (like a multicopter). This is useful for
people wanting to learn to fly prop-hang on 3D planes
Removes the need for plane to do the math for finding the relative height.
Also caches the value at the same time we update current_loc, which is a
non behaviour change as that was the only time you could see a change in
the relative height propegate through the system anyways
this will reduce confusion when searching for FLIGHT_LAND_* and you get a bunch of takeoff related hits. It will also make more sense when the landing library fully manages the FLIGHT_LAND stage entirely because it will not mange FLIGHT_LAND_ABORT
