Buildbot: Tweaks to current macOS config

Also disable CUDA binaries for now, those would need some extra work.

Fix weight paint Blur, Smear and Average breakage in multi-paint mode.

This is most pronounced in Auto-Normalize + Multi-Paint. Unlike
vertex paint, the weights being painted on in weight paint mode
don't necessarily correspond to the weight actually stored in
any one vertex group, and may instead be a computed aggregate.

This restores original code behavior lost in rB4f616c93f7cb.

Eevee : Add a setting for the number of indirect light bounce.

This is used to tweak the overall spread of the lighting. It is a per renderlayer setting.

LightProbe : Fix UI : display panels.

Cleanup: Remove some old pre 2.5 IPO code

Eevee: LightGrid: Fix progressive rendering.

Object Mode : Add probes data outlines and selectability

This required some small changes to the data display shaders so that they match the way the object mode renders them.
Strangely enough, I had to remove the normal attribute from the display code because it was being not bound as soon as I created another rendering call in object mode. The problem may be deeper but I did not have time for this so I derive the normal from the sphere pos.

DRWCache: Add a new regular Quad buffer.

Fix vertex paint w/ subsurf drawing

Only use alpha blending when in vertex paint mode.

Merge branch 'master' into blender2.8

Fix vertex paint smear tool

Checking surrounding verts wasn't working properly.

Vertex Paint minor improvement w/ smear

Note that this tool seems like it might need to be rewritten
since results are quite strange.

Projecting on the view vector gives a small improvement though.

Weight Paint: accumulate support

- Clamp accumulate so it doesn't exceed brush strength.
- Was multiplying by brush strength twice.

Cleanup: de-duplicate copied code w/ vertex paint

Fix T52943: don't export curves objects with no faces to Cycles.

Also skip any objects with zero ray visibility and meshes with
zero faces.

Fix Cycles OpenCL compiler error after recent changes.

Cleanup: split out tools & utils from vertex paint

paint_vertex.c was getting too big, move all code unrelated to
mode switching and modal painting into their own files.

Also replace vertex-color operators region redraw tag /w notifiers.

Merge branch 'master' into blender2.8

Drop platform support for Solaris & AIX

These platforms didn't see maintenance in years.
This commit just removes ifdef's & cmake check.

GNUmakefile: add back 'git pull'

Seems this was removed by accident.
