Cleanup: rename dist -> depth

Prepare to add code that stores distance to the ray, avoid confusion.

Cleanup: remove unused struct member

Merged with soc-2016-pbvh-painting, no longer needed.

Disable cursor drawing while navigating

Was performing ray-casts in sculpt mode on every update.

Fix sculpt secondary color missing some brushes

Cleanup: use bool for brush checks

Fix brush reset (missing notifier)

CMake: use restrict w/ gcc, not clang

Fix setting the operator name in Py operator API

Fix passing the same argument twice to BLI_strncpy

CMake: add -Wrestrict for GCC

PyAPI: fast keyword parsing for bpy modules

No functional changes.

Fix incorrect CUDA remaining time estimate after previous commit.

Merge branch 'blender2.8' into greasepencil-object

Fix: Palettes were getting freed before GPencil datablocks on exit

Merge branch 'id_override_static' into asset-engine

Add needed option to handle or not override's reference pointer when remapping.

There are cases where we'll want to also override the reference pointer
(when we actually switch that datablock itself), but in some specific
situations, like when creating a new override, we need to keep org
pointer here!

Cycles: CUDA faster rendering of small tiles, using multiple samples like OpenCL.

The work size is still very conservative, and this doesn't help for progressive
refine. For that we will need to render multiple tiles at the same time. But this
should already help for denoising renders that require too much memory with big
tiles, and just generally soften the performance dropoff with small tiles.

Eevee : Fix T52991

Fix use of uninitialized memory in Cycles normal baking.

Code refactor: zero render buffers outside of kernel.

This was originally done with the first sample in the kernel for better
performance, but it doesn't work anymore with atomics. Any benefit was
very minor anyway, too small to measure it seems.
