AP_Math: Compiler warnings: nuke fast_atan2()
...
per Randy's suggestion, fast_atan2() is no longer necessary over atan2() because only copter uses it and copter is no longer supported on future builds of APM

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

Add AVR compatibility header for missing math.h definitions.
...
- Define float versions of math functions to the double versions
on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.
