Math: added mul_transpose() operation
...
this is equivalent to multiplying by m.transposed(), but is more
efficient

Math: moved matrix multiple operations to .cpp file
...
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space
We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space

Math: added rotate() method to Matrix3f
...
this is the core method used to update the DCM matrix with a gyro
vector. Moving it to AP_Math allows us to have a test for it

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

::transposed does not change the matrix; make it const.

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.

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.
