Randy Mackay 3f0f2d1f7e AP_GroundEffect: latch takeoff_expected only while on the ground
Restores the pre-PR latch: takeoff_expected is set while armed and
land_complete and only cleared by the release check, so an altitude
release is not undone by a later dip below GNDEFF_ALT and modes that
disable it (THROW) never see it in the air.

Also clamps GNDEFF_TMO before the unsigned conversion, only trusts the
takeoff XY anchor for the drift gate when it was captured with a valid
horizontal position, and renames the drift define to say it is a NE
distance.

OpenSSF Best Practices

ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors. Our autopilot software is capable of controlling almost any vehicle system imaginable, from conventional airplanes, quad planes, multi-rotors, and helicopters to rovers, boats, balance bots, and even submarines. It is continually being expanded to provide support for new emerging vehicle types.
