This change will make handling of liboverrides hierarchies (especially
resyncing) much easier and efficient. It should also make it more
resilient to 'degenerate' cases, and allow proper support of things like
parenting an override to another override of the same linked data (e.g.
a override character parented to another override of the same
character).
NOTE: this commit only implements minimal changes to add that data and
generate it for existing files on load. Actual refactor of resync code
to take advantage of this new info will happen separately.

Previously, node selection made no distinction between a frame node and
other nodes. So a frame node would be selected by their whole rect or
center (depending on box/lasso/circle select). As a consequence of this,
box and lasso could not pratically be started inside a frame node (with
the intention to select a subset of contained child nodes) because the
frame would be selected immediately and tweak-transforming started.
Circle selecting would always contain the frame node as well (making
transforming a subset of nodes without also transforming the whole frame
impossible).
Now change selection behavior so that for all selection modes only the
border [the margin area that is automatically added around all nodes,
see note below] of a frame node is considered in selection. This makes
for a much more intuitive experience when arranging nodes inside frames.
note: to make the area of interest for selection/moving more obvious,
the cursor changes when hovering over (as is done for resizing).
note: this also makes the resize margin consistent with other nodes.
note: this also fixes right resize border (was exclusive instead of
inclusive as every other border)
Also fixes T46540.
This adds an option to the "Select Similar" operator in edit mode to
select vertices based on vertex crease similarity. The implementation
follows that of the edge crease, with a 1-dimensional KD-tree used to
store and retrieve vertex indices base on crease values.
To maintain compatibility with old files (scripts), the `SIMEDGE_CREASE`
enumeration identifier remains `CREASE`, while the one for the new
`SIMVERT_CREASE` is `VCREASE` to follow the naming convention of other
enum values.

Regression in 51befa4108
caused negative values to overflow into a uint64_t.
Resolve by casting to a signed int from originally signed types.
This caused D14033 not to work properly.
Assign the actual value before casting to large uint64_t/double types.
This improves readability, especially in cases where both pointer
and integer casts were used in one expression, to make matters worse
clang-format treated these casts as a multiplication.
This also made debugging/printing the values more of a hassle.
No functional changes (GCC produced identical output).
Account for `CurveEval`, which stores the proper deformed and
procedurally created data, unlike the `nurb` list, which has always
just meant a copy of the original curve.
Also account for the case when the curve is empty by using a -1, 1,
fallback bounding box in that case, just like mesh objects.
The problem was that nullptr was returned which is a valid value for
Mesh * and hence the returned optional was treated as having some value.
There was no check for point clouds so that was fixed as well.

Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

This patch makes it possible to set the UI color of a node's
header bar and override the default from the node's typeinfo.
Currently the color is taken from the `.nclass`
member of the node's bNodeType->TypeInfo struct.
This is created once when registering the node.
The TypeInfo is used for both UI and non-UI functionality.
Since the TypeInfo is shared, the header bar for the node
can't be changed without changing all nodes of that type.
The Map Range node is shown as a `Converter` or blue color by default.
This patch allows this to be changed dynamically to `Vector` or purple.
This is done by adding a `ui_class` callback to node typeinfo struct.

If the "Asset Indexing" option was disabled in Preferences > Experimental
> Debugging, the asset-view template (used by pose libraries for
example) would still use the indexing.
Previously, nearest interpolation filter was used for preview, because
it offered good performance and bilinear was used for rendering. This
is not always desirable behavior, so filter method can now be chosen by
user. Chosen method will be used for preview and for rendering.

Dashed line display was changed since 2.7x, using white on black
instead of grey on black.
This made selection difficult to see as white is brighter
than the default selected color.
Match the grey used in 2.7x.
This patch from Henrik Dick improves the continuity between the
grid forming corners and the edge polyons on multisegment bevels.
For details, see patch D13867.
Fixes T95384. New exporter was missing a fix for T94516 that recently got applied to the python exporter.
Also changed the obj export tests code so that when save_failing_test_output is requested and MTL result is different from the golden expectation, it is saved as well, similar to how it's done for the OBJ file result.
This change from Aras further parallelizes wihin large meshes (the previous one
just parallelized over objects).
Some stats: on A Windows machine, AMD Ryzen (32 threads):
(one mesh) Monkey subdivided to level 6: 4.9s -> 1.2s (blender 3.1 was 6.3s; 3.0 was 49.4s).
(one mesh) "Rungholt" minecraft level: 8.5s -> 2.9s (3.1 was 10.5s; 3.0 was 73.7s).
(lots of meshes) Blender 3 splash: 6.2s -> 5.2s (3.1 was 48.9s; 3.0 was 392.3s).
On a Linux machine (Threadripper, 48 threads, writing to SSD):
Monkey - 5.08s -> 1.18s (4.2x speedup)
Rungholt - 9.52s -> 3.22s (2.95x speedup)
Blender 3 splash - 5.91s -> 4.61s (1.28x speedup)

Caused by rBf75449b5f2b04b79, which was missing a null check when
attempting to extract a `CustomData` pointer from an mesh that might
be null if the object isn't a mesh object. The commit added null checks
elsewhere, so simply adding them here is a straightforward fix.
Fixes T95526, T95539
Also fixed conflicts due to the change in file writing in the new obj exporter
in master, and fixed one of the tests that was added in master but not 3.1.
The new wavefront .obj exporter in 3.1 was producing slightly invalid parm line syntax (missing u), and was not setting first/last N params to zeroes and ones for curves with "endpoint" flag properly.
