unittest: make tests more granular

Syncing: update layercollection tree when a new scenecollection is added

Add nesting collections into unittest

Temporary UI for layer/collections (for debug/testing)

Make hide/hide_select icons dynamic

From review: "doxygen"

I do not compile doxygen (assuming it is compiled, I do not even know). But it does not hurt to add the extra * everywhere

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

Fresh morning fixup of iterator logics

(and fix unfreed memory)

Fixup on BKE_scene_objects_Iterator_next

Use FOREACH_OBJECT_FLAG in more places

Reworked logic of iterators

otherwise I could not get different iterators based on a flag (SELECT), which is used everywhere in object_relations.c
The alternative would be to split every function in object_relations.c into _all, and _selected

Using an iterator to go over objects, and use this for library_query

This is not the ideal iterator (it loops over the scene collection tree 3x).
One solution (I want to discuss with Bastien Montagne @mont29) is whether to store the *parent of a SceneCollection to help with that. That would speed things up, and cost less memory.

We do not even need to store it in the file, since it can be re-generated at read time

Iterator util function

From review: curly brackets reinforcement

(even though the other related functions are not following this rule ... How I miss a code refactor dev!)

From review: move nodetree syncing of layers to util function

From review: do_versions_after_linking skipped on undo

From review: blo_do_versions_280_after_linking > blo_do_versions_after_linking_280

From review: use typedef for callbacks
