Fix T52634: EditMesh Remove doubles could hang

A single diagonal axis was used for sorting coordinates,
the algorithm relied on users not having vertices axis aligned.

Use BLI_kdtree to remove doubles instead.

Overall speed varies, it's more predictable than the previous method.
Some typical tests gave speedup of ~1.4x - 1.7x.

BLI_kdtree: utility function to remove doubles

Compositor / Render Layer Node: Fix wrong layer after deleting view layers

I was calling the ntree syncing function too late. So the index of the layer
was -1 since it was no longer in the ListBase, making all RenderLayer nodes
to decrease their respective `custom1` (even going to negative sometimes).

Fix Cycles incorrect principled BSDF mixing with some parameter variatons.

Spotted by Ha Hyung-jin, thanks!

Fix error in fill stroke thickness

To avoid gaps, the thickness of the internal strokes must be reduced, but the previous code only worked when the factor was different of 0.

Merge branch 'blender2.8' into greasepencil-object

Rename "lazy Mouse" to "Stabilizer"

Also changed "Radius" to "Distance"

Thanks Pablo Vazquez for the feedback.

Fix FOREACH_OBJECT_RENDERABLE using stack data

Since 30a966a7262308 when I removed the recursion, the code was still relying
on stack data. This would crash in release often, and it should crash always.

Big thanks to Sergey Sharybin for spotting the issue.

Fix FOREACH_OBJECT_RENDERABLE going over the same object twice

Which is really silly because we were already tagging the ids, but simply
never checking them back.

Fix T52520: Metaballs in edit mode causes infinite Cycles viewport reset

The issue was introduced by eb016eb as a fix for T41258, which added depsgraph
tagging with zero flag. The comment was saying that it's to make derived caches
to be updated, however bot sure how that could possibly work: tagging ID for
update with 0 flag only sets updated tags in bmain in old dependency graph.

In the new depsgraph, where object data is a part of depsgraph, doing such a
tag forces object to be updated, which re-triggers viewport rendering, which
is causing such an infinite viewport render rest.

Can not reproduce any crashes here, so maybe it's fine to move on with this
change.

Fix FOREACH_OBJECT_RENDERABLE recursion going over the roof

This was leading to so much recursion that it was failing here.
How to test it: Open wanderer.blend and try to render (F12).

Note: This won't fix F12 rendering for wanderer with Eevee. Something else is
going wrong there.

Cleanup: warning, spelling
