Math: added vector3.rotate() and matrix3.rotation() methods
...
these operate on a "enum Rotation" which defines a set of standard
rotations. These are much faster than our previous method, plus use
less memory

Back out the memset optimisation. It helps with code size but causes inexplicable link-time failures (undefined references to __cxa_pure_virtual).
...
Thank you very much Mr GCC. Can I have my evening back?

Minor code size optimisation; use memset to zero *this rather than explicitly assigning zero to the vector elements. Still not quite optimal for matrix3 as it gets three memsets, but still cheaper in terms of code size.

AP_Math - initialise vector2 and vector3 x,y,z values to zero. Doug found (and I confirmed) that if vectors or matrices were declared in a function (i.e. a local variable), they would often have non-zero values. Global declarations don't have this problem - it's a C++ performance thing it seems.

Rather than subclassing from the templated classes, just typedef directly to them.
...
This should solve the issues related to assigning to the convenience types.

Beginnings of a math library for ArduPilot(Mega) systems.
...
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.
