[Canberrauav] geo-fencing

I've added geo-fencing support to ArduPlane today. That gives us another
of the basic features we need for the outback challenge. I'm hoping to
test it on the SkyWalker tomorrow at CMAC.

The default setup is to fly back to a defined "return point" on fence
breach, which is what I will test tomorrow. For the OBC we will instead
set a pin on the APM high, which will be read by the failsafe device to
engage the failsafe mode.

Cheers, Tridge
