Revert "Depsgraph: Link from material to object shading"

The change was initially needed for Blender 2.8 branch but the actual
function was reverted in there. So no reason to keep dead unused
placeholder in the dependency graph.

This reverts commit fd69ba225540cde5e4c1fa651fb02df21ea0a143.

Merge branch 'master' into blender2.8

Draw Manager: No need of glScissor for external engines

Cycles integration with Draw Manager

We can now use object and other modes on top of Cycles.
Since we are now always on "render_to_view" (old Rendered mode), the
pause button is always visible.

OCIO: Fix crash cause by bad IMM usable.

Cycles: Fix CUDA split kernel

Global size y needs to be a multiple of 16.

Cycles: Cache split kernels in CUDA device

This way we don't re-load kernels for every sample in the viewport.
Additionally, we don't risk global size changed inbetween of samples.

Fix edit mesh not updating in cycles

Merge remote-tracking branch 'origin/master' into temp-cycles-denoising

Cycles Denoising: Fix shadowing pass calculation

Cycles Denoising: Cleanup offset calulation

Cycles Denoising: Only store lower-triangular parts of XtWX matrix

This saves 55 floats per pixel, which is quite significant with GPU tile sizes.

Merge remote-tracking branch 'origin/blender2.8' into temp-cycles-draw-manager

RNA: Remove remaining relevant scene->basact and BaseLegacy

Note: In one case (rna_Scene_editmesh_select_mode_set) I had to resort
to the temporary solution of BKE_scene_layer_context_active.

This is fine for now, but it will be a problem once workspaces are
introduced. In this case the fix is to use a temporary value in the set
routine, and actually only set the active object in the update function
(which can take bContext).

Merge branch '28' into workspaces

Add scene argument for notifiers

From workspaces branch

OCIO: Fix crash cause by bad IMM usable.

Use iterator for for do_version_workspaces_after_lib_link

Disabling USE_WORKSPACE_MODE works again

Use uppercase for macros
