Lucas De Marchi fa6f2c6b67 AP_Math: fix some coding style mistakes
- fix alignement of &
    - remove const from bool arguments

Gustavo Jose de Sousa 9d34b3b996 AP_Math: AP_GeodesicGrid: make all methods static
Since all members are.

Gustavo Jose de Sousa 8e8ab3af96 AP_Math: AP_GeodesicGrid: remove section_triangle() function
That function was only being used by the unit tests and the benchmark. In order
to remove memory usage, the triangles will be removed, since we don't actually
need to keep them in real situations. Thus, this patch removes that function
and copy those triangles to the test and benchmark.

Gustavo Jose de Sousa 0ff05b7af3 AP_Math: test_geodesic_grid: test triangles indexes
That helps figuring out which intermediate step failed the high level call.

Gustavo Jose de Sousa 4398e1e49b AP_Math: AP_GeodesicGrid: change order of triangles
- Change the order of the icosahedron triangles so that there's a uniform way of
finding the opposite triangle. The order visually still makes sense.

 - Change test to accommodate the order change.

Gustavo Jose de Sousa b299261ad4 AP_Math: AP_GeodesicGrid: add first implementation
The search for the geodesic section is still naive in this version.
Additionally, add unit tests.

Function to calculate determinant. Additionally, add unit tests.

Lucas De Marchi 348b07609c AP_Math: remove macros from unit tests
Avoid warnings like:

Use EXPECT_TRUE() and EXPECT_FALSE() from gtest instead.

dgrat 41661f815f AP_Math: Replace the pythagorous* functions with a variadic template
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.

Lucas De Marchi 880f130670 AP_Math: fix loss of precision on float addition
When using wrap_180_cd() we are adding a small float (180 * 100) to a
possibly big number. This may lose float precision as illustrated by the
unit test failing:

    OUT: ../../libraries/AP_Math/tests/test_math.cpp:195: Failure
    OUT: Value of: wrap_180_cd(-3600000000.f)
    OUT:   Actual: -80
    OUT: Expected: 0.f
    OUT: Which is: 0

dgrat 49cfd6fd9b AP_Math: Add gtest support for some functions
These functions (or variants thereof) now have unit tests:

  - is_zero()
  - is_equal()
  - sq()
  - pythagorous()
  - constrain()
  - wrap_180()
  - wrap_360()

Some tests in wrap_180_cd are failing: -180 should be wrapped to 180,
not -180.

Lucas De Marchi ceea7540fd AP_Math: rename test file
This will be reused for more math tests.

Lucas De Marchi 180359d6dd AP_Math: fix unit test
For ROTATION_ROLL_90_PITCH_68_YAW_293 consider the angles as 90, 68.8
and 293.3 degrees to pre-calculate rotation. This matches the rotation
matrix used in code.

While at it, check not only the values are close enough but also the
length of the vector.

Lucas De Marchi ba3325ffd3 AP_Math: rename rotation
The rotations are supposed to follow the name of the enum, in order. The
ROTATION_YAW_293_PITCH_68_ROLL_90 was added with the name of an
intrinsic 321 rotation, but the matrix is actually a 123 rotation,
following the other rotations already present.

Change the name to follow the other names.

Gustavo Jose de Sousa 4266e924d0 AP_Math: add unit test for vector rotations
This unit test already shows that rotation is wrong for
ROTATION_YAW_293_PITCH_68_ROLL_90.
