There is still a crash that you get because the draw manager needs to
handle duplis differently.
But the initial assert caused by this particular file is now fixed.
Since we are ditching layers from Blender (2.8) we need a replacement to
control groups visibility. This commit introduces collections as the building
blocks for groups, allowing users to control visibility as well as overrides
for groups.
Features
========
* Groups now have collections
This way you can change the visibility of a collection inside a group, and add
overrides which are part of the group and are prioritized over other overrides.
* Outliner
Groups can inspect their collections, change visibility, and add/remove members.
To change an override of a group collection, you need to select an instance of
the group, and then you can choose "group" in the collection properties editor
to edit this group active collection instead of the view layer one.
* Dupli groups overrides
We can now have multiple instances of the same group with an original "override"
and different overrides depending on the collection the instanced object is part
of.
Technical
=========
* Layers
We use the same api for groups and scene as much as possible.

Instead of storing a single active view-layer in the workspace, one is
stored for each scene the workspace showed before.
With this, some things become possible:
* Multiple windows in the same workspace but showing different scenes.
* Toggling back and forth scene keeps same active view-layer for each scene.
* Activating workspace which didn't show current scene before, the current view-layer is kept.
A necessary evil for this is that accessing view-layer and object mode
from .py can't be done via workspace directly anymore. It has to be done
through the window, so RNA can use the correct scene.
So instead of `workspace.view_layer`, it's `window.view_layer` now (same
with mode) even though it's still workspace data.
Fixes T53432.
You can now override loc/rot/scale of objects and posebones.
Also added a basic operator to make an override of active linked object,
but this is very limited/wip/testing feature (you have to manually override
object and its armature, and relink to proper local overrides
yourself...). Final 'make proxy killer' will be much more automated of
course.
There might be much more logic involved there, also we might not know proper
evaluated CoW pointer there yet. So we leave this to dependency graph to
decide what exactly to do here.
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

The loc one (shift-alt-G) was same as 'remove selected from active group'
action... Clear delta transform is not a common operation, so we can
live without a default shortcut for it.
Note that using same key (G) in same space for two completely different
kind of operations is probably a rather bad thing, nice topic for future
keymap work. ;)
Probably nice to have in 2.79a.
This is a final step of having proper ownership. Now selecting different
layers in the "top bar" will actually do what this is expected to do.
Surely, there are still things to be done under the hood, that will happen
in a less intrusive way.
While getting rid of Scene->base we got the following fixes:
* Fix "Convert To" operator
* Fix "NLA allowing to selected objects that are not selectable
* Fix scene.objects (readonly, no option to link/unlink)
Note: Collada needs to use the context SceneLayer for adding objects
however I added a placeholder, so Collada maintainers can fix this
properly.
This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
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.
Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.
The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.
This change in behavior means that curve handles have to be updated
when the modifier is added, removed or its options change. Due to the
way code is structured, it seems it requires a helper link to the
containing curve from the modifier object.
