Cycles: Minor cleanup, whitespace around keyword and preprocessor indent

Cycles microdisplacement: preserve smooth normals for linear subdivison

This way we prevent cracks in the model due to discontinuous normals, by using
smooth normals for displacement instead of always getting flat normals after
linear subdivision.

Removed most particle system code from RNA.

Fix T47754: Meshes glitch on cycling Viewport Shading mode with Linked Groups

This is a regression since 4310128 which is cased by really bad logic:
there might be dependencies between dupli-objects, which means _if_ we
really want to ensure derived mesh on dupli creation we have to do it
before any matrix is overwritten.

I'm not sure if such derived mesh trick is really the only way to go
without major refactor, but seems simple fix for now will do it.

Missed last commit

Correct UI messages: hyphenate 'add-ons'

Removed most partical-related code from UI scripts.

There are a lot of cases here where deciding for removal is a bit tricky.
Many features have options for "use_particles" and similar settings. Only
features which actually store a particle object reference or work on actual
particle data have been removed.

Cycles: Add missing velocity attribute to builtin image loader

For some reason other parts of blender importer were assuming velocity
is supported, but actual loader was not aware of that.

Fix T47443: Circle & UV Sphere aren't aligned

Change the starting point of the UV sphere so that it is aligned with the circle, cylinder, and cone primitives.

CMake: ignore header

CMake: Partially revert recent missing headers commit

The header which was put to the CMake project is not by any means used
during compilation, it is only used when manually updating CUDA wrangler
from CUDA headers.

Cleanup: use bool
