Merge branch 'master' into greasepencil-object

Cleanup: draw manager headers

Cleanup: redundant defines

Comment or remove unused defines.

Cleanup: remove blender-internal update flag

Cleanup: wrapper for built-in shader access

DRW: support clipping for empty object

Keymap: move grease pencil Alt-C to 2.7x map

This has been removed from the default map, so don't use elsewhere.

Cleanup: avoid static vars to store legacy shaders

GPU: refactor defines into GPUShaderStages

Code comment notes there are "just a few",
now there are enough it's useful to include in GPUShaderStages.

Cleanup: order GPUShaderStages (vert, geom, frag)

Use names for declarations to support adding defines, coming next.

Workbench: Depth Of Field: Add toggle option in shading popover

Pretty straight forward. Just an option to turn the DoF per viewport.
Default is off as in 2.79.

Workbench: Depth Of Field: Cleanups

GP: Apply scale to particles

The particles were using the scale of the original object and the thickness of the stroke was not correct. Now, the scale is applied by particle.

GP: Set cyclic to OFF when use cutter

When cut a stroke, the cyclic must be set to off because keep it gets very weird results.

Ammend to rBea5326df86cb.

As suggested by @sergey, better use RECALC flag dedicated to pointcache.

Fix T58142: Crash when use Cycles to render stereoscopy

This is a quick workaround to prevent the crashes with multi-view.
The ultimate solution can be plenty, and would turn around refactoring
Cycles to handle multi-view internally, so that depsgraph could be freed
before render with no problems.

Fix Freestyle (ASAN detected) crash

This was very simple to reproduce, just turn on Freestyle and press render.

Now to the truth of things. Most (if not all) of
~BlenderStrokeRenderer() can be removed. I believe this was done back
when freestyle was using G.main, and since we gave freestyle its own
main we can just leave the cleanup for later.

I will leave this for freestyle maintainers to think over though.

Note: There is a chance this was the issue reported on T57890. I will
wait for the reporter to confirm this as fixed though.

Fix T60783: (Certain) shapekeys stopped working in 2.8.

This commit adds another optional check (when `--debug-io` is set) on
write .blend process, to check and ensure all shape keys have their
'from' pointer properly set to their respective user ID.
This is intended to be used as debuging tool mostly (to try to detect
when/why some of those pointers can become NULL).

For now, it also systematically perform same checks/fixes when loading a
.blend file, to fix all broken ones laying around. Later we might move
that usage to a do_version instead, but for now think it's safer to
always perfom it (and it's rather cheap process anyway).
