Global: rename min and max macros to uppercase
...
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

AP_Math: Move simple math function implementations to header for better

compile time optimization
Functions like sq() are better moved to the header file as inline.
Compiler can then optimize these out when used in code, this saves cpu
cycles with stack push, pop during function calls.

AP_Math: standardize inclusion of libaries headers
...
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.

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

The vector classes are light adaptations of work by Bill Perone
(billperone@yahoo.com ), the Matrix3 class draws on them for
inspiration.
Bill's matrix classes are too heavyweight and not templated, so
they're less suitable for us here.
This code compiles, and some trivial tests seem to work, but
it should not be considered "golden" yet.
