Fix T49981: New Depsgraph - When camera is on inactive layer, it does not evaluate constraints

Cycles: Attempt to fix compilation error on ppc64el

There is some define conflict between system headers and clew,
so delay include of clew.h as much as possible.]

This is something which needed to be done in the code before
the refactor, hopefully such change will still work.

Depsgraph: Fix infinite viewport object update in CYcles render mode

The issue was caused by wrong object re-tag needed to have proper dependnecies
update for OpenSubdiv.

Depsgraph: use more explicit parenthesis

Merge branch 'master' into HMD_viewport

Conflicts:
source/blender/makesrna/intern/rna_userdef.c

Cycles: Remove unneeded lines in constructor

Since these were added to `device_memory` we don't need them in
`device_vector` as well.

Cycles: Minor style change

Cycles: Remove uses of nullptr

We're avoiding C++11 language features for now.

Cycles: Simpler use of sizeof

Less likely to make mistakes later if something here needs to change.

Cycles: Add comment to explain disabled code

Merge branch 'master' into cycles_split_kernel

Cycles: Simplify and make atomics more clear

Somehow I missed the other versions of the atomic functions in
`atomic_ops.h`. This is just to switch to those to make the code
more clear.

Fix Xcode link error, missing definitions in RNA C++ API that other compilers ignored.

Cycles: Don't shadow loop variable

bugfix / performance fix and new option "constrained collison"

bugfix: switching from kinematic to simulated should work now, performance improvements with dynamic fracture,
new option just exposes the disable collision flag to FM (works inverted here, enable it to let constrained objects collide, disable for default behavior)

Cycles: add basic backwards compatibility for device selection, move to System tab.

For the multi-GPU case users still have to reconfigure the devices they want to use.

Based on patch from Lukas Stockner.

Cycles: refactor culling code into utility class.

Cycles: distance culling for objects.

This can be used together with camera culling to keep nearby objects visible in
reflections, using a minimum distance within which objects are visible. It is
also useful to cull small objects far from the camera.

Add a dropdown to support multiple lens-distortion shaders

Cleanup: harmless mistake in rangetree
