PyAPI: correct function name w/ arg parsing

Minor optimization: avoid 2x hash, adding to set

Minor optimization to skin operators

- store layer lookup
- single hash adding to set

Fix T47615: crash trying to use point density with lamp object.

Cycles: Fix compilation error of certain OpenCL split kernels

Fix T42536: Normals modifier: Generated normals can be opposed to face one, needs winding flipping in this case.

BKE_mesh: add polygon flipping tools.

Those new functions invert the winding of polygons, effectively inverting their normals.

A helper was also added to allow swapping two items in customdata layers.

Being able to invert normals outside of BMesh area is very important in several places,
like IO scripts or customnormals modifiers...

Differential Revision: https://developer.blender.org/D1814

Cleanup: rename `CustomData_swap` to `CustomData_swap_corners`.

More in line with our other func names handling sub-item data (mainly, tessfaces' UVs and VCol...).

Fix T47608: Cycles cage baking crash after recent uv derivative fixes.

Fix T47605: Elsyiun theme info text hard to read

Fix T47582: Curve handle thickness regression

Fix T47586: Nurbs handle thickness regression

Fix T47583: Mesh wire edge thickness regression

Cleanup split creator.c

creator.c was getting hard to follow.

- Split off argument and signal handling into own files.
- Move docstrings next to functions (to keep docs grouped with code).

Fix T47592: Wrong line width w/ custom-bones

Docs: early exist build process on error

Don't attempt to build docs when generation fails.

Docs: Add missing context members

Buildbot: Rename i386 to i686, we don't support pre-i686 CPUs anyway

Fix T47596: Bone motion path - confusing UI in 3DView tools.

Now using same UI as in object/armature properties, also save one line in 3DView panesl. ;)

Nothing crucial there, but nice & safe to backport to 2.77 imho.

Buildbot: Support build in a newer chroot
