This patch goes away form using C++ RNA during tangent space calculation which avoids quite a bit of overhead. Now all calculation is done using data which already exists in ccl::Mesh. This means, tangent space is now calculated from triangles, which doesn't seem to be any different (at least as far as regression tests are concerned). One of the positive sides is that this change makes it possible to move tangent space calculation from blender/ to render/ so we will have Cycles standalone supporting tangent space.
