Refactor mball util function, untested

I have not address MBalls directly, so there are probably other parts that are required to conform to the new code before consider than useful

unittest: bpy.ops.object.duplicate

Handle main object dupli functions

Missing: mesh separation, material split, mesh conversion (curve to mesh)

I hereby declare layers syncing fully implemented!

Use more of the FOREACH macros in screen_context.c

object/base iterator refactor + add FOREACH_VISIBLE_BASE

Using static for prototypes

Basic Implementation of GTAO :
There is still artifacts to remove and optimisation to do.

Tag areas of code that require TODO_LAYER_COPY

Merge remote-tracking branch 'origin/blender2.8' into render-layers

Manual fix: collection.c layer.c

Fix unittest for cases where we set render_layer but not scene_collection

Fix context operator test

We needed a fallback for the cases where the layer was specified but not a scene_collection

BKE_scene_layer_has_collection

Util function to check if a SceneCollection is linked to a SceneLayer

This is needed for corner cases of bpy.context.scene_collection when the context render_layer mismatches the context scene_collection.

Left-over from previous commit (remove OBJECT_OT_move_to_layer)

Remove OBJECT_OT_move_to_layer

Link objects in scene using ObjectBase

Update selected_editable_bases to use ObjectBase

Remove base from BKE_object_groups_clear

Remove OB_FROMGROUP from base, and add util funcs to sync base/object flags

I still want to remove the syncing of base/object flags. But for now
this will at least help future refactor.

ObjectBase need a flag for from_dupli temp objects
