AP_Math: bug fix to wrap_360 and wrap_180
...
angles above 720deg and below 3200deg might not have been properly
wrapped.
wrap_360_cd could return 36000 when really this should be wrapped back
to zero.

AP_Math: update location code to avoid float rounding
...
this avoids manipulating global coordinates as float variables. Using
a float reduces our precision from 1cm to about 70cm.
This also adds location_diff() which will be used in the L1 controller
to avoid global positions in floats
