Cycles: make displacement a supported feature.

Adaptive subdivision remains experimental, still needs more work.

Cycles: add Vector Displacement node and extend Displacement node.

This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.

Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

Differential Revision: https://developer.blender.org/D1734

Eevee: Fix crash when using Ogl render and subsurface.

Eevee: Render: Fix hashed-alpha testing.

Eevee: Render: Make sure all probes are refreshed before rendering.

Eevee: Perf: Put transparent sorting before the render loop.

Eevee: Render: Add ambient occlusion pass support.

Eevee: Subsurface: Release separate albedo texture if not used.

Eevee: Render: Fix emission shader normal output

Fix draw manager F12 evaluation mode

This effectively allows for ob duplicator_render/viewport to work properly
when doing final renders.

fix: rBc4a19e988bb4 error stepped in by a merge from mmaster

Collections: Operator to duplicate a collection

When duplicating a layer collection directly linked to the view layer we copy
the collection and link it.

For all the not directly linked layer collectionns, we try to sync the layer
collection flags, overrides, ...

Also we make sure the new collection is right after the original collection.

We also expose this in RNA, via collection.duplicate().

Collections: Operator to select collection objects

This is only supported by layer collections (the ones accessible
in the outliner when you see "View Layer").

Merge branch 'master' into blender2.8

Fix missing group duplicated by hair in render

Was happening when viewport visibility on the particle system is disabled.
This became an issue after c45afcf, but the actual issue goes a bit deeper
and the following aspects were involved:

- Relations builder for particle system was ignoring particle system if
it's visibility is not enabled for viewport. This is something what
shouldn't have been done -- depsgraph relations are supposed to be the
same no matter if it's viewport or render.

- Relation builder was only dealing with duplication set to object, but
was ignoring group duplication.

This is technically a regression in 2.79a-RC as well, so would need to
backport this fix to the branch after extra testing is done here in the
studio.

fix: silence warnings about unused local variable (thanks to dfelinto for the hint)

Fix T53980: IK influencing REST POSE with New Depsgraph

Merge branch 'master' into blender2.8

Cleanup: wrap function args

Fix T53978: Bad memory access after recent fix to BSDF mixing

Added proper checks after BSDF allocation and cleaned up existing
inline checks.
