Cycles: Fix compilation error when building without Glog and no C++11

Merge branch 'master' into blender2.8

Conflicts:
source/blender/editors/space_view3d/drawobject.c

Eevee: Fix world test for volumetric

Compiler even throws a warning at this.

Third fix for my merge: crash after switch to edit mode reported by @dfelinto

Fix T51834: Active Object and Groups color difference imperceptible

16 was not enough here, -32 seems to give OK results.

One more fix for merged 'normal map tangents not working correctly when there are no UV maps.'

Merge branch 'master' into blender2.8

Conflicts:
source/blender/makesdna/DNA_particle_types.h

Fix T51965: Custom Bone Shape Wireframe setting affects wireframe thickness.

Clearing of custom bones outline's line thickness was not done at proper
point, wireframe drawing never changes line thickness, only solid draw
with outline does...

Fix T51703: Rigid body with delta transform jumps when transforming

When doing any transformation on a rigid body object that has delta
transforms, the object would be offset by the amount of the delta
transform.

Eevee: Fix Closure define.

Better fix for rigid body not resimulating

Last fix only accounted for direct changes to the RB settings, but
failed for, say, object transformations. This fix accounts for any
change that might invalidate the RB cache.

Fix rigid body not resimulating after cache invalidation

Fix 9cd6b03187b91bb2c267a45eac3cee7738e0e220 introduced a bug that
prevented simulation after a cache invalidation (for instance when
changing a setting after simulating). This fixes that.

Eevee: Add support for volumetrics in node tree.

Only volume scatter is implemented for now.

GPU Codegen: Add new closure socket type.

This allow specialized shaders to redefine the closure interface to fit their needs.

For instance, Volumetric closure needs to pass more than one vec4 (absorption vec3, scattering vec3, anisotropy float).

Eevee: Initial implementation of Volumetrics.

Draw Manager: Add new blend mode for transmission.

This blend Mode is doing Source + Destination * Alpha.

Eevee: Fix luma calculation for lamp fresnel.

Fix edit mode not drawing

This was introduced on 1ad0cc6bde.
