AP_Math: correct Polygon_outside floating point instatiation
...
This routine was entemplatificated from the integer version, which was
designed to be perfect across representable ranges of points. The
floating point version suffered from a rounding problem.

Global: remove mode line from headers
...
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

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

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'
