Fix mistakes (wrong copy/paste :/ ) in previous commit.

CMake: Fix order of libraries to address linking errors on Linux

Amber assets: add more editing UI.

Fix T53109: denoising variance debug passes not working after recent changes.

Fix compositor node links getting lost on file load for custom render passes.

Depsgraph: Introduce hash of dependency graphs in the scene level

The idea is following: we do need to have multiple dependency graphs to denote
different scene layers (depsgraph should only contain objects from a specific
scene layer), and we also want to support same scene layer to be evaluated to
a different state in different windows. In order to achieve that we do need to
have a list or hash (for faster lookup presumably) somewhere. To keep things
easier for now, it will be a scene which owns that hash. This seems to make
sense anyway, since dependency graph only points to data which is owned by
scene.

This commit only introduces some basic API and hash itself stored in DNA, there
is no changes in behavior. See this as a first step towards getting rid of
scene-global dependency graph.

Depsgraph: Remove redundant call of depsgraph free

Remove unused dependency graph flags from scene

Remove some residue of old legacy dependency graph

Cleanup: Use modifier scene

Merge branch 'greasepencil-object' of git.blender.org:blender into greasepencil-object

Cleanup: Rename passindex to pass_index

Fix T46163: NLA properties with drivers aren't displayed as having drivers

While such drivers will generally get evaluated too late to be of much
use during animations, it can still be useful to allow using drivers to
control a whole bunch of NLA strip properties (i.e. syncing NLA strip
timings via a single property/control).

Keyframe insertion however is still not allowed on these properties
(and an error message will now be displayed when trying to do so,
instead of silently failing), as it is useless.

Merge branch 'master' into blender2.8

Cleanup: redundant casts

Cleanup: redundant casts

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' into blender2.8

Cleanup: replace gpencil tri vars w/ array

Fix/properly implement: "make group proxy"

This was never correctly implemented. It now works as expected (ala 2.79 behaviour).
The proxy object is added to all the collections of the original empty.

Before not only this wasn't the case, but it would crash Blender.
