The previous design is rather old and has a couple of problems:
* Scalability: The current solution of adding little icon buttons next to the
data-block name field doesn't scale well. It only works if there's a small
number of operations. We need to be able to place more items there for better
data-block management. Especially with the introduction of library overrides.
* Discoverability: It's not obvious what some of the icons do. They appear and
disappear, but it's not obvious why some are available at times and others
not.
* Unclear Status: Currently their library status (linked, indirectly linked,
broken link, library override) isn't really clear.
* Unusual behavior: Some of the icon buttons allow Shift or Ctrl clicking to
invoke alternative behaviors. This is not a usual pattern in Blender.
This patch does the following changes:
* Adds a menu to the right of the name button to access all kinds of operations
(create, delete, unlink, user management, library overrides, etc).
* Make good use of the "disabled hint" for tooltips, to explain why buttons are
disabled. The UI team wants to establish this as a good practise.
* Use superimposed icons for duplicate and unlink, rather than extra buttons
(uses less space, looks less distracting and is a nice + consistent design
language).
* Remove fake user and user count button, they are available from the menu now.
* Support tooltips for superimposed icons (committed mouse hover feedback to
master already).
* Slightly increase size of the name button - it was already a bit small
before, and the move from real buttons to superimposed icons reduces usable
space for the name itself.
* More clearly differentiate between duplicate and creating a new data-block.
The latter is only available in the menu.
* Display library status icon on the left (linked, missing library, overridden,
asset)
* Disables "Make Single User" button - in review we weren't sure if there are
good use-cases for it, so better to see if we can remove it.
Note that I do expect some aspects of this design to change still. I think some
changes are problematic, but others disagreed. I will open a feedback thread on
devtalk to see what others think.

Otherwise it would just show empty space where the icon is supposed to
be.
Unfortunately this icon is upscaled quite a bit and doesn't look too
great. Would be good to improve but not a high priority.

This makes it possible to trigger a refresh of the data-block preview,
available next to the preview in the Asset Browser sidebar. The previews get
easily outdated and automatically refreshing it all the time is not an option
because it would be a consistently running, quite expensive process. So a
button to cause a refresh should be reasonable.
This button can also be used to switch back from a custom preview to a
generated one. Although that may not be clear, and we should probably think of
a way to explain that better.
Addresses T82719.

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", opening a File Browser from a File or Asset Browser as
regular editor would cause some issues. For example after closing the
temporary File Browser, the regular browser would take over the file
path and display settings from the temporary one. This is because they
used to share the same area data.
Some similar issues may have happend with temporary image editors.
Now, this commit finally separates the space data of temporary maximized
editors from the regular ones. So the editor data is entirely
independent now, as it should be.

The Asset Browser will be a sub-editor of the File Browser. This prepares the
File Browser code for that.
**File-Lists**
* Support loading assets with metadata read from external files into the
file-list.
* New main based file-list type, for the "Current File" asset library.
* Refresh file-list when switching between browse modes or asset libraries.
* Support empty file-lists (asset library with no assets).
* Store file previews as icons, so scripts can reference them via icon-id. See
previous commit.
**Space Data**
* Introduce "browse mode" to differeniate between file and asset browsing.
* Add `FileAssetSelectParams` to `SpaceFile`, with `FileSelectParams` as base.
Makes sure data is separated between asset and file browsing when switching
between them. The active params can be obtained through
`ED_fileselect_get_active_params()`.
* `FileAssetSelectParams` stores the currently visible asset library ID.
* Introduce file history abstraction so file and asset browsing can keep a
separate history (previous and next directories).
**General**
* Option to only show asset data-blocks while file browsing (not exposed here).
* Add "active_file" context member, so scripts can get and display info about
the active file.
* Add "active_id" context member, so `ED_OT_lib_id_load_custom_preview` can set
a custom ID preview. (Only for "Current File" asset library)
* Expose some of `FileDirEntry` in RNA as (non-editable). That way scripts can
obtain name, preview icon and asset-data.

For the Asset Browser, it needs to be possible to drag assets into various
editors, which may not come from the current .blend file. In other words, the
dragging needs to work with just the asset metadata, without direct access to
the data-block itself.
Idea is simple: When dragging an asset, store the source file-path and
data-block name and when dropping, append the data-block. It uses existing drop
operators, but the function to get the dropped data-block is replaced with one
that returns the local data-block, or, in case of an external asset, appends
the data-block first.
The drop operators need to be adjusted to use this new function that respects
assets. With this patch it only works for dragging assets into the 3D view.
Note that I expect this to be a short-lived change. A refactor like D4071 is
needed to make the drag & drop system more future proof for assets and other
use cases.

This makes it possible to turn data-blocks into assets and back into normal
data-blocks. A core design decision made for the asset system is that not every
data-block should be an asset, because not every data-block is made for reuse.
Users have to explicitly mark data-blocks as assets.
Exposes "Mark Asset" and "Clear Asset" in Outliner context menus (currently ID
Data submenu) and button context menus. We are still not too happy with the
names, they may change.
This uses the new context members to pass data-blocks to operators, added in
af008f553293 and 0c1d4769235c.

Object previews are really helpful for visual data-block selection, like asset
browsing. Having them be generative should also be quite handy and should work
well enough in many, if not most cases.
What this does is simple:
* Place the object (actually a deep copy of it, for thread safety) in a virtual
.blend into an empty scene/view-layer.
* Add a camera, point it towards the front of the object, assuming that means
pointing towards its +Y axis.
* Use "Camera Fit Frame to Selected" logic to put the object into frame.
* Create a threaded off-screen render.
Of course, such an automatic preview will not work in all situations. E.g. it
currently does a bad job capturing a single plane. We could add options for
more advanced automatic previews, but probably custom previews is more
important, which I committed already (812ea9184221).

No automatic preview generation will ever be good enough to cover all cases
well. So custom preview images are a must for a preview driven data-block
selection - like for asset browsing.
The operator simply allows selecting an image file, which will then be read and
copied into the data-blocks preview (resized if necessary).
There's no UI for this currently and the operator won't be available in the
search menu yet. It will later once the Asset Browser UI is merged.

This is similar to c4a2067130130d, but applies to the general UI and is only
about single data-blocks. Here there was a similar problem: How can buttons
pass the data they represent to operators? We currently resort to ugly ad-hoc
solutions like `UI_context_active_but_get_tab_ID()`. So the operator would need
to know that it is executed on a tab button that represents a data-block.
A single button can now hand operators a data-block to operate on. The operator
can request it via the "id" context member (`CTX_data_pointer_get_type(C, "id",
&RNA_ID)` in C, `bpy.context.id` in .py).
In this commit, it is already set in the following places:
* Generic RNA button code sets it to the pointed to data-block, if the button
represents a data-block RNA pointer property. (I.e for general data-block
search buttons.)
* Data-block selectors (`templateID`) set it to the currently active data-block.
* The material slot UI-List sets it for each slot to the material it represents.
The button context menu code is modified so its operators use the context set
for the layout of its parent button (i.e. `layout.context_pointer_set()`).
No user visible changes. This new design isn't actually used yet. It will be
soon for asset operators.

* Avoid direct access to `SpaceFile.params`, use a getter instead. This matters
because once the asset-browser changes are in, there will be an alternative
selection parameter object. The getter can return the correct one.
* Rename the function to ensure the parameters. The old name
`ED_fileselect_get_params()` wasn't a mere getter, it would create the
parameters if necessary. Now we have an actual getter, so better be clear.
* In some instances, I replaced the old "get" function with the new mere
getter. So the ensure logic is called less often. However, in these cases we
should be able to assume the selection parameters were created already as
part of the editor creation routine.
The term "active" in the new function names may seem a bit odd in the current
context, but that is a preparation for the Asset Browser merge as well. Like
said, there will be two file selection parameter objects in the space.

During the development of the new nodes in the `geometry-nodes` branch
the color of the new nodes wasn't considered, so all of the nodes ended
up red, the color for "input" nodes. This patch introduces two new
colors, one for "Geometry" and one for "Attributes". There are only two
attribute nodes currently, but the next sprint will add two more,
attribute mix, and sample from texture. The attribute nodes are
conceptually different enough from the nodes that modify the geometry
that they deserve their own color.

Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.

This option joins any stroke with an end near the actual stroke. Now it is not limited to the last stroke, any stroke in the same layer for the actual frame can be joined. The join can join two strokes drawing a third stroke.
If the end and the start of the result stroke are very small, the stroke is changed to be cyclic automatically.
There is a limit distance to join the stroke, if the distance is greater than this value, the strokes are not joined. Actually, a constant, threshold distance is used, but we could expose
as a parameter in the UI in the future.
The tool can be used with freehand drawing or with primitives.
Note: Great part of the patch is just a refactor of the old code to make it accessible and to keep code organized.

Issue exposed by rB4c7b1766a7f1.
Main idea is that non-memfile first undo step should check into previous
memfile and tag the ID it is editing as `future_changed`.
That way, when we go back and undo to the memfile, said IDs are properly
detected as changed and re-read from the memfile.
Otherwise, undo system sees them as unchanged, and just re-use the
current data instead.
Note that currently only Sculpt mode seems affected (probably because it
is storing the mode switch itself as a Sculpt undo step instead of a
memfile one), but similar action might be needed in some other cases
too.

When painting in the image editor on data images (Non-color, Raw) the
color mismatched between the sampled color and the actual effect that
the painting has on the image. The root cause is that the sampling is
color managed, but the painting still uses a fixed color management
pipeline with a lot of assumptions. Due to recent changes the drawing
of the image editor is color managed, but the painting isn't what made
these changes show up.
This patch is a work-a-round so that the sampled colors and the effect
the paint has on the texture matches. This isn't the correct solution
as that would be to migrate all the painting tools to use proper color
management.

Consistently return `false` from `ED_object_parent_set()` when parenting
is not possible. Before, when parent and child were the same object, the
function would return `true` even though the parent-child relation was
not made.
Just returning `false` in the `parent == child` case would break the
parenting operator, as `false` stops its loop over all selected objects.
This tight coupling caused T82312. The loop now has its own check for
this, so that it properly continues, and the implementation of
`ED_object_parent_set()` is decoupled from its surrounding code.
