This replaces lost functionality from the old GN Attribute Map Range node.
This also adds vector support to the shader version of the node.
Notes:
This breaks forward compatibility as this node now uses data storage.

This patch refactors the instance-realization code and adds new functionality.
* Named and anonymous attributes are propagated from instances to the
realized geometry. If the same attribute exists on the geometry and on an
instance, the attribute on the geometry has precedence.
* The id attribute has special handling to avoid creating the same id on many
output points. This is necessary to make e.g. the Random Value node work
as expected afterwards.
Realizing instance attributes has an effect on existing files, especially due to the
id attribute. To avoid breaking existing files, the Realize Instances node now has
a legacy option that is enabled for all already existing Realize Instances nodes.
Removing this legacy behavior does affect some existing files (although not many).
We can decide whether it's worth to remove the old behavior as a separate step.
This refactor also improves performance when realizing instances. That is mainly
due to multi-threading. See D13446 to get the file used for benchmarking. The
curve code is not as optimized as it could be yet. That's mainly because the storage
for these attributes might change soonish and it wasn't worth optimizing for the
current storage format right now.

Resolving the path to a missing pose-bone (for example),
was not raising an error as it should have.
Regression introduced in f9ccd26b03,
which didn't update collection lookup logic to fail in the case the
key of a collection wasn't found.
Use "filepath" which is the current convention for naming full paths.
- Main use "name" which isn't obviously a file path.
- BlendFileData & FileGlobal used "filename" which is often
used for the name component of a path (without the directory).
The const argument makes sense because these are the "source"
sockets, even though a const cast is necessary at one point.
The name "interface_socket" is an improvement over "stemp"
because the latter sounds like "temporary", or it confuses
the old socket template system with a node group's interface.
This node outputs the current scene time in seconds or in frames.
Use of this node eliminates the need to use drivers to control values
in the node tree that are driven by the scene time.
Frame is a float value to provide for subframe rendering for motion
blur.

This patch adds a layer_idx and pass_idx parameter to the rna_Image_gl_load function. It exposes both to the Python API as optional parameters.
This allows python scripters to specifiy which layer and pass they want to load in to an OpenGL texture. Right now image.gl_load() always takes the first layer and first pass.
This is limiting when working with multilayer openEXRs.
With this patch scripters can do something like this:
```
pass_idx = area.spaces.active.image_user.multilayer_pass
layer_idx = area.spaces.active.image_user.multilayer_layer
image.gl_load(frame=0, layer_idx=layer_idx, pass_idx=pass_idx)
```
As the parameters are optional and default to 0, it should not break existing code.

When a manual frame range is set, allow marking an action as having
Cyclic Animation. This does not affect how the action is evaluated,
but the Cycle-Aware Keying option will automatically make any newly
added F-Curves cyclic. This allows using the option from the start
to build the cycle, rather than only for tweaking an existing loop.
The curves are made cyclic when they have only one key, either
after inserting the first key, or before adding the second one.
The latter case avoids the need to manually make the first added
curve cyclic after marking a newly added action cyclic.

Some operations, e.g. adding a new action strip to NLA, require
knowing the active frame range of an action. However, currently it
can only be deduced by scanning the keyframes of the curves within
it. This is not ideal if e.g. curves are staggered for overlap.
As suggested by Nathan Vegdahl in comments to T54724, this patch adds
Action properties that allow manually specifying its active frame range.
The settings are exposed via a panel in the Dopesheet and Action Editor.
When enabled, the range is highlighted in the background using a striped
fill to distinguish it from the solid filled regular playback range.
When set, the frame range is used when adding or updating NLA tracks,
and by add-ons using `Action.frame_range`, e.g. FBX exporter.

Add an operator "Copy to Asset Library" for installing asset bundles
into already-existing asset libraries.
The operator is shown when:
- the "Current File" library is selected,
- the blend file name matches `*_bundle.blend`, and
- the file is not already located in an asset library.
The user can select a target asset library, then gets a "Save As"
dialogue box to select where in that library the file should be saved.
This allows for renaming, saving in a subdirectory, etc.
The Asset Catalogs from the asset bundle are merged into the target
asset library.
The operator will refuse to run when external files are referenced. This
is not done in its poll function, as it's quite an extensive operator
(it loops over all ID datablocks).

Asset libraries should be directories on disk. By manually entering a
file path it was possible to have a single blend file as asset library,
but that was not a designed-for situation, and it doesn't play well
with the asset catalog system.
Original implementation was a quick prototype which should have never
landed as-is in master. It had very limiting constraints and did not
allow for any real further development.
This commit fixes the internal implementation to make more sensible,
maintainable and evolutive.
NOTE: This commit introduces another forward-incompatibility in the
Blender file format: Files saved after this commit won't open properly
in older versions of blender regarding local inserted constraints or
modifiers into overrides of linked data.
NOTE: Technical details: The 'anchor' item name/index is now stored in
`subitem_reference_` members, and the actual 'source' item name/index is
stored in `subitem_local_` members of the override property operation
data.
Previously, only the `subitem_local_` members were used, storing the
anchor item name/index, and assuming the 'source' item was always the
next in the list.

Constraints, modifiers and NLA tracks can now report from RNA whether
they are defined as comming from the override's reference linked data,
or are local to the override.
The existing RNA CollectionRef class only offers a length() operation
which is sometimes used for checking if the collection is empty. This is
inefficient for certain collection types which do not have a native
length member; the entire list is iterated to find the count.
This patch creates an explicit empty() method to be used in such cases
for better semantics. Additionally, many collection types will behave
more efficiently when using the new method instead of checking length.
Making use of the new method will follow separately.

This feature has been desired for some time:
- https://rightclickselect.com/p/ui/Tqbbbc/allow-navigating-while-transforming (See comments);
- D1583;
- T37427;
In short, blocking navigation during transform limits the user to move the object only to visible areas within the screen and hinders the allocation of objects within closed meshes.
The node editor is also impaired because some nodes are far between them and the connectors are too small.
The only disadvantage of this patch (as I see it) is the conflict with the existing key map:
MIDDLEMOUSE:
- enable axis constrain in 3D view;
WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY:
- change the threshold of the proportional edit;
So the patch solution was to change these keymaps:
- MIDDLEMOUSE to Alt+MIDDLEMOUSE;
- WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY to Alt+(corresponding key);
When you use this new keymap for the first time in the proportional edit, it may seem strange due to the custom of using it (both in View2D and View3D).
But quickly the user gets used to it.
Alternatively we can add an option to the user preferences ([] Allow navigating while transforming). (I'm not much fan of this option).
The patch was done on branch2.8. But maybe it's a good idea to apply it to 2.79
