MAVLink: moved mavlink variables back to library
...
these were moved to the main sketches to allow for compile time
selection of MAVLink 0.9 vs 1.0. We no longer support 0.9, so we can
move it back, which simplifies some test sketches

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
