RNA: expose mesh vertex alpha

Note that some import/export scripts will need updating

Collada: export vertex-color alpha

Vertex Paint: Alpha Support

GSOC 2017 by Darshan Kadu, see: D2859.

This is a partial merge of some of the features from
the soc-2017-vertex_paint branch.

- Alpha painting & drawing.
- 10 new color blending modes.
- Support for vertex select in vertex paint mode.

Code cleanup: remove unnecessary buildbot code after macOS library upgrade.

Eevee: Probe Grid: Clear Grid buffers with world diffuse coefs.

This make sure the values displayed by the "show data" sphere are initialized.

Also this make the bounce lighting progress more apparent.

Eevee: Probe Grid: Add "progressive rendering"

This gives the user a more rapid preview of what the final result will be.

The grid cells are renderer in a series of powers of two offsets.

macOS: officially upgrade to 10.9 libraries from lib/darwin.

This removes a bunch of code that is no longer needed, and running
"make update" will now automatically download the new libraries.

Fix T52574: make Cycles rendered tile counter more clear.

Cycles: reduce subsurface stack memory usage.

This is done by storing only a subset of PathRadiance, and by storing
direct light immediately in the main PathRadiance. Saves about 10% of
CUDA stack memory, and simplifies subsurface indirect ray code.

Fix T52086: Graph editor "normalize" drag errors for integers

Merge branch 'master' into blender2.8

Fix T52932: Driver with target of custom property from scene fails to update

Note that this is only supported in new depsgraph.

Merge branch 'master' into blender2.8

Curves: Fix wrong bitset being checked against CYCLIC bit flag

Based on report from Talos Security Advisory.

Adding paint brushes crashes w/ linked libs

While we could skip this for linked files,
convention so far is to only update startup.

Cleanup: switch fall-through warning

CMake: move MSVC warnings to central location

Missed in last merge from master

Local changes built, but merge-commit needed amending.

Eevee : TAA : Fix conflict with outlines.

The previous view was incorrectly considered valid even if the persp matrix was different. So the history depth was mismatching.

Object Mode Engine: Small cleanup
