Cleanup: order from a-z structs in BKE_collection.h and BKE_layer.h

Eevee: SSS: Fix SSS with Add Shader node.

Eevee: Add SSS objects to probe rendering.

This does NOT do the SSS diffusion when rendering probe but at least you can see your object without SSS in reflections / bounce light.

Fix Opengl Error with glBlitFramebuffer

This was caused by 93936b8643b9c4f77fe13d35b41ecaa246843dd8

From GL spec :
GL_INVALID_OPERATION is generated if mask contains GL_DEPTH_BUFFER_BIT or GL_STENCIL_BUFFER_BIT and the source and destination depth and stencil formats do not match.

So blitting framebuffer with depth or stencil require the SAME FORMAT.

Smoke: Pass non-trivial arguments by const reference

Fix compilation error with clang-5

Alembic: Fix mismatch in forward declaration with definition

Enable antialiasing while drawing

The antialiasing was not activated for previous strokes, only for current.

Fix missing SpinLock typedef on macOS

Fix: Temporary fix for crashes when moving GP keyframes when toggling Onion Skinning

ANIM_list_elem_update() was not doing anything as ale->id was null,
and we were filtering the channels by "animdata" blocks (i.e. the GP
datablocks). While technically what we're doing here isn't totally
correct (I'll need to come up with a better fix tomorrow), this will
be a good quick-fix for the crashes they animators are currently getting.

Add stdlib include for utildefines

Ideally we could just declare abort, but this has attributes
based on the platform, so include stdlib instead.

Fix T53068: AMD Threadripper not working well with Blender

The issue was caused by SpinLock implementation in old pthreads we ar eusing on
Windows. Using newer one (2.10-rc) demonstrates same exact behavior. But likely
using own atomics and memory barrier based implementation solves the issue.

A bit annoying that we need to change such a core part of Blender just to make
specific CPU happy, but it's better to have artists happy on all computers.

There is no expected downsides of this change, but it is so called "works for
me" category. Let's see how it all goes.

Fix compile errors after merge

Merge branch 'blender2.8' into greasepencil-object

Conflicts:
source/blender/blenloader/intern/versioning_280.c

Remove the guide_object pointer from HairSystem.

Scalp mesh now is passed explicitly to the hair API functions again.

The idea is that hair systems can be created in any object and use
another object as the scalp. Sharing the same hair pattern should be
implemented at a later time, pending a good design for assigning
follicles to specific hair systems.

Cleanup: Remove unused code

Cycles: Modify kernel_indirect_background to remove call to svm_eval_nodes

Speeds up kernel building by another 2-3 seconds. Rendering is
another 1% slower.

Cycles: Add shader_eval_state to allow eval of ray states besides RAY_ACTIVE

Cleanup: order BLI before BKE headers

This was done nearly everywhere already

Cleanup: remove BLI_blenlib from ghash header

This causes source files to depend on ghash header
for BLI_string/rect/listbase.

Also quiet warnings.
