Andrew Tridgell 7c9c26e2b7 AP_Math: re-work polygon algorithm for perfect precision
using sign checking and 64 bit integer math only when needed results
in an algorithm that is just as fast as the floating point version,
but has perfect results for any representable lat/lng

Andrew Tridgell 7442ba31d8 polygon: improve the speed and precision of the polygon algorithm
now takes 156 usec per test, with a 11 point boundary

Andrew Tridgell 1ab2b416a3 geofence: store fence points as int32_t
this keeps maximum precision in fence boundaries

Andrew Tridgell 3ddfc6664a AP_Math: better polygon algorithm
this one seems to do better with single precision floating point

Andrew Tridgell f4bd3cb5a2 AP_Math: added Polygon_complete() function
used to veryify user supplied boundaries

Andrew Tridgell cd9fb3c47a AP_Math: added a Polygon_outside() function
this tests if a point is outside of a polygon. This will be used as
part of our geo-fencing support, and also for a new 'fenced mode'
