The old code did not work when there were multiple ids with
the same name (which can happen when ids are linked in).
The solution is to use the session ids instead. Those are different
even when two ids have the same name.

Display a "disabled hint" (text explaining why something isn't possible)
when dragging a material over the 3D View, while being in edit mode or
so (anything that isn't object mode).
Previously, `ImageTile->ok` and `ImageUser->ok` were used to indicate
whether an image failed to load. There were three possible values
which (probably) had the following meanings:
* `0`: There was an error while loading the image. Don't try to load again.
* `1`: Default value. Try to load the image.
* `2`: The image was loaded successfully.
This image-wide flag did not make sense unfortunately, because loading
may work for some frames of an image sequence but not for others.
Remember than an image data block can also contain a movie.
The purpose of the `->ok` flag was to serve as an optimization to avoid
trying to load a file over and over again when there is an error (e.g. the
file does not exist or is invalid). To get the optimization back, the patch
is changing `MovieCache` so that it can also cache failed load attempts.
As a consequence, `ibuf` is allowed to be `NULL` in a few more places.
I added the appropriate null checks.
This also solves issues when image sequences are used with the
Image Texture node in Geometry nodes (also see D12827).

rB43bc494892c3 switched `BKE_libblock_relink_to_newid` to use new ID
remapping and libquery code.
However, that new code does protect by default against remapping an
objects's data pointer when that object is in Edit mode, since this is
not a behavior that generic BKE code can handle (due to required editing
data for most obdata types when in edit mode).
So specific code that does create new IDs and need remapping in Edit
mode has to pass specific exception flags to remaping code.
This commit adds those remapping flags to `BKE_libblock_relink_to_newid`
and add said exception flag to the remapping call from
`ED_object_add_duplicate` when the object is in edit mode.
The location of a linked object isn't editable, or at least it will be reset
when reloading the file. So the drag & drop shouldn't even pretend like this
would work, so disable the snapping of the object and the bounding-box to show
the snapped object location while dragging.
When dragging an object in non-object mode into a 3D View, there will now be
red text explaining that this is only possible in object mode.
The previous commit enabled this.

Actions of duplicated objects would not be properly made single user,
unlike obdata and materials.
Further more, there is no reason to manually handle such animdata
copying here, `BKE_id_copy_ex` can do that for us with the proper flags.
Now 'Make Single User' will also create local copy of linked data as
needed.
IMPORTANT: Unlike with local data, this always happen, even if linked
data has only one user. This avoids e.g. cases like two local objects
sharing a same linked mesh, then when calling 'Make Single User ->
Object and ObData' on both objects, yu expect both of your objects to
get localized meshes, not one of them keeping its linked, un-editable
mesh.
Use arrays for wmEvent coordinates, this quiets warnings with GCC11.
- `x, y` -> `xy`.
- `prevx, prevy` -> `prev_xy`.
- `prevclickx, prevclicky` -> `prev_click_xy`.
There is still some cleanup such as using `copy_v2_v2_int()`,
this can be done separately.

Adds a button, Update All Paths, to the Motion Paths property tabs and
will always show. The operator goes through all visible objects and
updates their motion paths.
The current implementation has a subtle functional change. Calculating
or updating motion paths for armature objects (through the Object tab,
not Armature tab) now also updates the paths for its bones. We could
preserve the old behavior but it doesn't seem necessary. It seems more
likely that the animator wants to update both anyways.

Object deletion was reporting the number of objects deleted,
causing tests to print noisy output.
Now this is information is only included when invoked.
This should not be allowed in general, added some initial call to check
when user is allowed to delete a data to search for mandatory override
usages...
`BKE_object_material_slot_used` would only check obdata usages, but
particle settings can also (weirdly enough) use objects' material slots.
So now, as its name suggests, `BKE_object_material_slot_used` does take
an object as parameter, and also checks for potential slot usage from
psys in the object.
This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

This adds a toggle to node group inputs exposed in the modifier to use
an attribute instead of a single value. When the toggle is pressed, the
button switches to a text button to choose an attribute name. Attribute
search isn't implemented here yet.
One confusing thing is that some values can't be driven by attributes
at all, like the size of a primitive node. In that case, we should have
a node warning, but that will be separate since it's more general.
We can also have an option to turn off this toggle in node group
input settings.
The two new properties for each input are stored with the same name
as the value, but with `"_use_attribute"` and `"_attribute_name"``
suffixes. The properties are not added for socket types that don't
support attribute input, like object sockets.

Creating some primitives allows for a scale value (via python) that will
scale the object accordingly. For objects with a radius parameter
(like cylinders, spheres, etc.) passing a scale different to (1,1,1)
would result in unexpected behavior.
For example:
`>>> bpy.ops.mesh.primitive_uv_sphere_add(radius=2, scale=(1,1,2))`
We would expect this to create a sphere with a radius of 2
(dimensions 4,4,4) and then be scaled *2 along the z-axis
(dimensions 4,4,8). But this would previously create a scaled sphere
with dimensions (2,2,4).
The scale was simply divided by two. Maybe because the "radius"
parameter for creating the primitives was confusingly named "diameter"
(but used as the radius).
The fix adds a scale parameter to `ED_object_new_primitive_matrix`
and also renames the wrongly named "diameter" parameters to "radius".

This patch allows dropping material assets from material slot under the mouse
cursor. Before this change the material slot had to be hand-picked from the
properties panel.
For consistency it is chosen to do this in any shading mode as the tooltip shows
what is exactly going to happen during release.
The feature also works for other object types than Meshes as it uses the drawn surface on the
GPU to detect the material slots. Performance of this patch has been tested with AMD GCN3.0
cards and are very responsive.

Previously, the Point Instance node in geometry nodes could only instance
existing objects or collections. The reason was that large parts of Blender
worked under the assumption that objects are the main unit of instancing.
Now we also want to instance geometry within an object, so a slightly larger
refactor was necessary.
This should not affect files that do not use the new kind of instances.
The main change is a redefinition of what "instanced data" is. Now, an
instances is a cow-object + object-data (the geometry). This can be nicely
seen in `struct DupliObject`. This allows the same object to generate
multiple geometries of different types which can be instanced individually.
A nice side effect of this refactor is that having multiple geometry components
is not a special case in the depsgraph object iterator anymore, because those
components are integrated with the `DupliObject` system.
Unfortunately, different systems that work with instances in Blender (e.g.
render engines and exporters) often work under the assumption that objects are
the main unit of instancing. So those have to be updated as well to be able to
handle the new instances. This patch updates Cycles, EEVEE and other viewport
engines. Exporters have not been updated yet. Some minimal (not master-ready)
changes to update the obj and alembic exporters can be found in P2336 and P2335.
Different file formats may want to handle these new instances in different ways.
For users, the only thing that changed is that the Point Instance node now
has a geometry mode.
This also fixes T88454.

Before this patch attempting to remove a particle modifier programmatically
through Python would fail, because it deleted the modifier associated with
the currently active particle system instead of the one passed as an argument
to `bpy.types.ObjectModifiers.remove()`.
This fix adds an additional argument for the particle system to
`object_remove_particle_system`. This allows to specify which particle system
and its associated modifier shall be removed. In case of
`particle_system_remove_exec` it will remain the currently active particle
system, whereas `object_remove_particle_system` passes the particle system
of the modifier. Hence, the correct modifier will be removed.
