Campbell Barton 2fe940f8df Fix for snapping pose bones with axis-angle rotation. 
- armature_mat_pose_to_bone() was missing axis-angle check.
- added loc_axisangle_size_to_mat4() for completeness.
- use 'const' prefix where possible in math rotation functions.

Campbell Barton 65b0893df0 bugfix [#21483] Twisting when Dupliframing a Surface Circle (Nurbs) along a Curve. 
use the curve's twist for follow path constraint and parent-path.

Campbell Barton c04850ec06 python mathutils change 
quat * quat was returning the dot product (a float), rather then the cross product.
 Use BLI_math's mul_qt_qtqt() function.

Campbell Barton e4a7087982 bugfix [#22836] Alt+MMB view alignment don't respect all axes directions 
also moved rotation_between_quats_to_quat into BLI_math from python mathutils.

Campbell Barton fde4686d77 barycentric transform utility geometry function. 
From 2 triangles and 1 point, the relative position between the point and the first triangle is applied to the second triangle to find the target point.
the barycentric weights are calculated in 2D space with a signed area so values outside the triangle bounds are supported.

wrapped by python:
 pt_to = Geometry.BarycentricTransform(pt_from, t1a, t1b, t1c, t2a, t1b, t1c)

NOTE: 
- moved some barycentric weight functions out of projection painting into the math lib.
- ended up making some of the math functions use const args.
TODO:
- support exceptional cases. zero area tries and similar.

* Pre-conversion commit removing old arithb.c code, this will not compile,
  next commit fixes that.

* Fix remaining issues before conversion.
* Inline various vector functions, currently enabled for all platforms.
  I expect this to work in GCC/MSVC at least, if other platforms don't
  support it, #ifdef's can be added.

Brecht Van Lommel 60ea745613 Math Lib Reorganization 
* New header and source files.
* Still need a few tweaks before switching code to use them.
