0af11a1742 Make use/computation of lnors consistant. 
Issue was, when requesting (building) lnors for a mesh that has
autosmooth disabled, one would expect to simply get vnors as lnors.

Until now, it wasn't the case, which was bad e.g. for normal projections
of loops in recent remap code (projecting along split loop normals
when you would expect projection along vertex normals...).

Also, removed the 'angle' parameter from RNA's `mesh.calc_normals_split`.
This should *always* use mesh settings (both autosmooth and smoothresh),
otherwise once again we'd get inconsistencies in some cases.
Will update fbx and obj addons too.

3debcc8b51 Math Lib: improve area calculation 
- area_quad_v3 now works correctly with concave quads.
- add area_squared_*** functions, to use when comparing to avoid a sqrt().

a5c3de2e49 Fix T42630: Triangulate returns invalid face-map 
Triangulate with beautify caused a bug when there were existing edges
could make the bmesh-operator return an invalid face-map.

Now the beauty is calculated on the 2d-tri's resulting from polyfill,
its simpler and faster.

3e7e97f127 BMesh: ensure iterator macros assign to valid types 
note, this is for C++ code which expects a cast, (will be added later)
also add a macro for nop-expressions (EXPR_NOP),
when we never want an expression to be evaluated, but it should still be valid.

149ca1320b Fix non-deterministic editmesh normal orientations 
- selecting a boundary edge would randomly point in/outside the face (now point away).
- selecting 3 verts would use the first selected edge as the tangent (now use longest).
- selecting 1 vert betweem edges, uses the edges to define the tangent.
