This should be purely an implementation change,
for end users there should be no functional difference.
The entire key configuration is in one file with ~5000 lines of code.
Mostly avoiding code duplication and preserve comments and utility
functions from the C code.
It's a bit long but for searching and editing it's also convenient to
have it all in one file.
Notes:
- Actual keymap is shared by blender / blender_legacy
and stored in `keymap_data/blender_default.py`
This only generates JSON-like data to be passed into
`keyconfig_import_from_data`, allowing other presets to load and
manipulate the default keymap.
- Each preset defines 'keyconfig_data'
which can be shared between presets.
- Some of the utility functions for generating keymap items still
need to be ported over to Python.
- Some keymap items can be made into loops (marked as TODO).

Use drag&drop to parent objects in the outliner by holding down shift.
Previously it was easy to accidently parent objects and there was no way to notice it immediatly.
In some views it is possible to parent objects without using shift; should be obvious from context.

Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.
In the outliner, right click > view layer > set indirect only. This is
like clearing camera ray visibility on objects in the collection, and is
temporary until we have more general dynamic overrides.
In the outliner, right click > view layer > set holdout. This is
temporary until we have more general dynamic overrides, but helps
Spring production for now.
This translates the gl calls to the new GPU_ wrappers from D3501.
Given it's tedious and repetitive work, this patch does as much as it can with search + replace, the remainder of the gl calls will need to be manually dealt with on a case by case basis.
This fixes 13 of the 28 failing editors when building without opengl.

In the outliner there are now icons for it, Ctrl+Click isolates a
single collections.
In the 3D view, Ctrl+H key opens a menu that is more or less the
equivalent of the old layer buttons in the header. Regular Click isolates
the collection, Shift+Click toggle the collection visibility. Pressing
number keys and letters works in this menu, which can help for quickly
selecting a specific collection.
Shortcuts for quick switching by just pressing 1/2/3/.. keys are available
again. The order can be confusing with nested collections, but that seems
unavoidable. The first numbers control the top level collections, and then
sub collections if numbers are left.
Remaining design issues:
* The 3D view menu needs to be improved: support for sub collections,
staying open on shift+click, access from the 3D view header somewhere,
shortcut key display.
* Currently collection hiding just controls per-object hiding, we plan
to separate this state still so alt+H doesn't affect collection hiding.
H hides selected objects, Shift+H hides unselected objects, and Alt+H
reveals hidden objects.
This hiding state is distinct from restrict viewport and render, and
meant for temporarily hiding objects without affecting more persistent
collection hiding.
Object hiding is per view-layer, same as selection. It affects the
viewport and any preview renders in there, but not final renders.
In the outliner, different icons are now used for temporary hiding, and
restrict viewport and render. Hidden objects are greyed out.
Remaining design issues:
* For lamps we probably still want to keep their effect on the scene,
currently they are fully disabled by hiding. Arguably mesh lights or
even objects being reflected or casting shadows are not that different
but perhaps the special lamp exception from local view should remain.
* We need a feature still to disabled this hiding for specific viewports,
for render or animation preview where you want to see the entire scene
while working in another view.
* We need a new icon for restrict viewport, for now it uses a grid similar
to the 2.4 icon.
* Hiding objects does not preserve selection state as it did in 2.7,
it's probably convenient to support this again?
OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

The outliner can redraw quicker without rebuilding the tree, for example when
just moving the mouse and highlighting different items. The way this worked is
that the outliner would be tagged to avoid rebuilding, however if another
operation that does require rebuilding happens in the meantime we could go out
of sync and crash.
* "Scenes" now shows for each scene lists of all view layers, collections and
objects contained in it. This is the place to see all collections and objects
in the scene even if they are not used in any view layer. Objects are nested
according to parenting here.
* "Collections" now shows all collections in the view layer, and the objects
in those collections. Objects are not nested by parenting, only collections
since it would be too confusing if the children are in a different collection.
* "Groups" is unchanged.
* "View Layer" was removed, replaced by "Collections".

Suggested by Pablo Vazquez (venomgfx).
The idea here is that it should be easy to work in the outliner by picking a
bunch of objects and adding them to a new collection.
Where is the new collection? In the same level as the "outliner active" object.
Note, since the outliner has no pure concept of an active object, I'm using
the highlight tag for this. Hopefully it works fine.
It should work in "Collections", "View Layer", and "Groups".
Only when collections are not filtered out.
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().
In the future we may have siblings to collections (like overrides) that are not
collections. This change make sure tooltips will keep working.
Note: This was originally wrongly committed together with a Collada fix,
re-committing separately now. See bd7060a87f.
I really would prefer if we were to use the dropbox API for this.
That said, we now have some tooltips that work.
I'm using the new draw callback draw API for outliner tooltips.
