The previous code to get unique instance ids did not actually ensure 100%
uniqueness. Now the code does and hence the "almost" from the name is removed.
In practice, this change likely does not have any impact because the fallback
case is very unlikely to be reached.

The fix is to detect when the compute context is recursive and to stop the
search early in that case. Currently, this does not generate a warning. There
will be a warning when trying to evaluate the recursive closure though.

Use `SocketValueVariant` for all the data-block types as well. Before it was
used for e.g. float, integer and menu sockets.
The only remaining type afterwards is the geometry socket which will be moved
separately.
Using `SocketValueVariant` for all socket types will simplify code later on and
also removes the need for dealing with raw memory in more cases.

Moves more animation theme properties shared by different editors to the new Common panel.
- Playhead (was shared by 7 editors)
- Marker Line (was shared by 5 editors)
- Marker Line Selected (was shared by 5 editors)
- Channel (was shared by 3 editors)
- Sub-channel (was shared by 3 editors)
- Channel Group (was shared by 2 editors)
- Active Channel Group (was shared by 2 editors)
In total, 27 properties are replaced with 7.
---
User Visible Changes:
- "Current Frame" is renamed to "Playhead". It was general sentiment among
Anim and UI modules to rename this everywhere after "Playhead Snapping" was
added, and this is first step towards that. Name is more recognizable and it's
clear it refers to UI element, rather than something as generic as "current frame".
- Channel, Sub-channel, Channel Group, and Active Channel Group colors in
Dope Sheet had alpha, but ones in Graph and NLA editors didn't. New common
property is used for all three of them and has alpha, meaning two editors gain
alpha as well, but they don't use alpha, still only Dope Sheet does.
- Channel and Sub-channel had different color in NLA and didn't match Dope Sheet
and Graph Editor, now since it's shared it has same color, which is a visual change
(slighlty lighter blue).

There should be minimal user-measurable changes since the old algorithm
is not the same as OpenSubdiv. For example now creases (both edge and
vertex ones) are properly supported.
This allows to have less dependencies on the old subdivision surface code
which ideally will be removed soon.

The title says it pretty much all: the shrinkwrap modifier is no longer
dependent on the legacy DerivedMesh.
The benefits for doing this are:
- The DerivedMesh is closer to be removed from the codebase.
- Only base vertices are subdivided which could result in better
performance and memory usage.
- Proper crease support (for edges and vertices).
The downside of using OpenSubdiv is that the topology refiner might be
expensive to calculate, so for meshes with a lot of extraordinary faces
(such as n-gons, triangles) the performance will be worse.

Mixing dynamic data with other data always results in dynamic now. While this
wasn't true without lists, it is true now and also makes sense generally. Also
mixing lists and single values or fields results in a list now.

This removes the `STRIP_DUPE_UNIQUE_NAME` and `STRIP_DUPE_ALL` macros
and replaces them with an `enum StripDuplicate`.
A flag with a value of 0 was implicitly used as "duplicate selected strips" so the
enum uses `Selected = 0` to document this behavior better.

The repeat zone color is changed back to the color it used in 4.5, to
avoid the need for people to re-learn the color. The closure socket and
zone share the same color, which is made more yellow-ish to distinguish
it from the bundle socket color.
This is fundamentally quadratic code until #140907 is implemented. However, the
old approach that didn't use `StringRef` was a few percent faster because it
didn't have to call `strlen` as often. So this brings back a little bit of
performance in cases like #140706.

This PR adds a flag to the pose bone that determines its visibility.
Doing so allows to hide a pose bone and
* don't affect other instances of the same armature
* save the visibility even if the rig is linked
The visibility of the bone in object mode is now also determined by the
pose bone whereas before it was the `Bone`.
**This breaks backwards compatibility** on the Python API since the visibility property,
on the `Bone` behaves differently now as it hides the edit bone instead of the pose bone.
In order to remove all active uses of `BONE_HIDDEN_P` the changes in `armature_skinning.cc` are required.

This patch redesigns the File Output node to provide better UX and UI.
This is mainly achieved by allowing the user to create inputs by
dragging into an Extend socket and adjust existing inputs using the
familiar UI list design available in Blender. Additionally, various UI
changes were done:
- The Use Node Format option was renamed to Override Node Format for
clarity.
- Socket types are now fixed and do not change as new links are made,
allowing users to specify the exact output type and employ implicit
conversion if needed.
- The distinction between images and Multi-Layer EXR was made clearer.
- Final output paths are drawn in the UI to remove guess work.
- The Base Path was split into a Directory and a File Name.
- Panels were added to group options, include a panel for the node
format, items, and item formats.

This patch improves warnings displayed when the user attempts to use
passes in render engines other than EEVEE with the viewport compositor.
Previously, an error icon was always displayed if the viewport
compositor was in use as well as a viewport overlay text. This error
existed even when the render engine was set to EEVEE and even if the
passes are not actually used, which was always confusing for users.
This patch improves this by only displaying the error when a pass is
actually used and when a non-EEVEE render engine is used.
This is implemented internally as an extra info callback for the node.
And the compositor_unsupported_message member hack was removed.

Replaces the `FPS` macro with `scene->frames_per_second()`.
The macro has two major issues:
* It hides that it depends on a `Scene *` variable named `scene`.
* It makes debugging harder.
This is now replaced with a member function on the scene.

Temporary directory handling had a logical error, assuming the
"session" temporary directory was owned and created by Blender
and could be recursively removed on exit.
However, it's possible creating the session sub-directory fails,
in that case the temporary directory was used for the "session".
This meant setting `C:\` as the temporary directory in the preferences
would attempt to recursively remove `C:\` on exit.
Resolve with the following changes:
- Only perform a recursive removal on the temporary directory
if a session sub-directory was created.
- If the creating the user-preferences temporary "session" sub-directory
fails fall back to the systems temporary directory and try to
create the "session" directory there.
Previously this was only done if the preference path didn't exist.
The preferences path was still used if it existed but couldn't be
written to.
Include a test to ensure this is working as expected.

The above commit changed many of the `wm.radial_control` default
keybinds used in various paint modes to support accessing the "unified"
properties on a per-mode basis. While the base Blender keymap and the
industry compatible keymap were updated, this change was not applied
to custom keymaps, leading to confusing behavior for the users.

Unit tests veryfying expectation for curves::nurbs::calculate_evaluated_num().
Expectation is computed from closed form expressions rather then hard coded
values. Purpose for this is to make the tests easier to adjust if, for example,
parameter sampling pattern is changed. It should also make them easier to read
and understand.
Additional purpose is to create a baseline and verify changes for #144000.
Implementation is essentially examples from:

The W channel in quaternion and axis-angle F-Curves is now themeable
(defaulting to yellow), instead of incorrectly blending the X and Y axis
theme colors.
The original blending math did not take into account that the hue
channel actually wraps around, and so the blended color became blue
instead of the intended yellow.
Instead of fixing the math, the theme has been expanded for this W axis.
The default color is set to the mathematically correct yellow.

The behavior of the field inferencing changed slightly. So instead of checking
if the link connects a socket that has a field to one that does not, check the
source is a field and the target does not support one. Note the difference
between "having a field" and "supporting a field".
This was probably broken in 7b7c630018.

Cryptomate's init process would access the scene's viewlayers even when
`build_meta_data` was false - and the `CryptomatteSession` constructor
would only ensure valid viewlayers if `build_meta_data` is `true`.
Triggered in a complex setup (BCon25 app template), but suspect this was
reproducible when the compo node tree is used in a non-active scene.
This commit introduces the extension modes to the corner pin node and
further streamlines the node properties by wrapping all props in the node
storage. Therefore, the interpolation mode has been removed from the
custom properties of the node and moved into the node storage.
Right now, the extension modes only work for non-anisotropic filtering.

Many nodes operate on all the instances that are passed into them. For example,
the Subdivision Surface node subdivides the mesh at the root but also instanced
meshes. This works well for most nodes, but there are a few nodes were the old
`modify_geometry_sets` function was not very well defined and it was tricky to
use correctly.
The fundamental problem was that the behavior is not obvious when a node creates
or modifies instances and how those are integrated with the already existing
instances.
This patch solves this with the following changes:
* Remove the old `GeometrySet::modify_geometry_sets` and related
`*_during_modify` methods.
* Add a new `blender::geometry::foreach_real_geometry` function that is similar
to the old `modify_geometry_sets` but has a more well-defined interface:
* It never passes instances into the callback. So existing instances can't be
modified with it.
* The callback is allowed to create new instances. This will automatically be
merged back with potentially already existing instances. The callback does
not have to worry about accidentally invalidating existing instances like
before.
* A few existing usages used `modify_geometry_sets` to actually modify existing
instances (usually just removing attributes). Those can't use the new
`foreach_real_geometry`, so they just get a custom simple recursive
implementation instead of using a generic function.

This was caused by a mismatch in the conditions that enabled GPU
subdivision. The mesh normals domain for meshes with no faces was
reported incorrectly, causing the code to think there are auto-smooth
style split normals when there actually aren't.
Also the GPU subdiv normals extraction had a crash binding a vertex
buffer that doesn't exist when there are no faces. Add an early return
for the wire-only mesh case to avoid that.

Generally, node names are expected to be unique within a node tree. However,
`ntree_shader_copy_branch` currently does not enforce this for performance
reasons. This was broken by recent changes in 5b73f798d0 and 9fd877e174 which
allows for passing already unique names and identifiers to the node copy
function.
The main problem here was that the `use_unique` parameter of the `node_copy`
function was not well defined. Now, this function is completely removed in favor
of using `node_copy_with_mapping` directly. This also has a new
`allow_duplicate_names` parameter now which makes the expected behavior more
explicit.

For quite a while, for edit mode mesh object evaluation we haven't
put the evaluated edit mesh in the evaluated geometry set. I don't
think the reason for that applies anymore. The code is much simpler
if all the evaluated geometry is a consistent place, so just put it there,
the same way as non-edit-mode evaluation.
