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 Cycles incorrect principled BSDF mixing with some parameter variatons.

Spotted by Ha Hyung-jin, thanks!

Merge branch 'master' into blender2.8

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

Fix T53943: Weight paint crash in new scene

Fix T50630: Fluid fails on win32 w/ unicode paths

Allow overriding gzip open w/ elbeem.

Fix crash drawing light probe

Fix light probe callbacks

Even though this wasn't crashing here, the arg types were wrong.

DRW / Render: Make render result show when using final render with eevee.

Eevee: Remove unused variable.

Eevee: Add Z pass render result.

Eevee: Display render button in render panel

Eevee: Add support for TAA/SuperSampling for final render.

Eevee: Add new "render samples" properties.

Eevee: Initial Final Render support.

TAA / multiple samples is not working at the moment.

Render: Abort operator if there is no render_to_image() function
