(Some minor changes done in the patch)
This corrects code that's currently disabled, see `USE_NURBS` define.
The name passed to `BKE_curve_add` was overwritten,
bypassing uniqueness and utf8 encoding checks.
Longer names would cause a buffer overrun as the length of the source
data was passed to `BLI_strncpy` instead of the destination.

This is an initial implementation of a USD importer.
This work is comprised of Tangent Animation's open source USD importer,
combined with features @makowalski had implemented.
The design is very similar to the approach taken in the Alembic
importer. The core functionality resides in a collection of "reader"
classes, each of which is responsible for converting an instance of a
USD prim to the corresponding Blender Object representation.
The flow of control for the conversion can be followed in the
`import_startjob()` and `import_endjob()` functions in `usd_capi.cc`.
The `USDStageReader` class is responsible for traversing the USD stage
and instantiating the appropriate readers.

After doing an import, the bounding box of the stroke was not calculated and any operation related to brushes (Sculpt, Weight Paint and Vertex Paint) was not working as expected because the bounding box of the stroke was wrong.
This problem was solved automatically after any edit operation, but must be solved in the import process.
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

This option will determine visibility on either render or the viewport
visibility. Same for modifer settings. So it will either evaluate the
depsgrah with DAG_EVAL_RENDER or DAG_EVAL_VIEWPORT.
This not only makes it more flexible, it is also a lot
clearer which visibility / modfier setting is taken into account (up
until now, this was always considered to be DAG_EVAL_RENDER)
This option was always present in the USD exporter, this just brings
Alembic in line with that.

When introduced in {rB61050f75b13e} this was actually working (meaning
it checked the Outliner OB_RESTRICT_RENDER flag and skipped the object if
desired).
Behavior has since then been commented in rBae6e9401abb7 and apparently
refactored out in rB2917df21adc8.
If checked, it seemed to be working (objects marked non-renderable in
the Outliner were pruned from the export), however unchecking that
option did not include them in the export.
Now it changed - for the worse if you like - in rBa95f86359673 which
made it so if "Renderable Objects" only is checked, it will still export
objects invisible in renders. So since we now have the non-functional
option with a broken/misleading default, it is better to just remove it
entirely.
In fact it has been superseeded by the "Visible Objects" option (this
does the same thing: depsgraph is evaluated in render mode) and as a
second step (and to make this even clearer) a choice whether
Render or Viewport evaluation is used can be added (just like the USD
exporter has). When that choice is explicit, it's also clear which
visibility actually matters.
This is breaking API usage, should be in release notes.

This adds support for importing UV sets which are defined per vertex,
instead of per face corners. Such UV sets can be generated when the
mesh is split according to UV islands, or when there is only one UV
island, in which cases only a single UV value can be stored per
vertex since vertices will never be on a seam.

Note that these changes are limited simple cases as these kinds of
changes could allow for errors when refactoring code when the known
state is not so obvious.
Read and write generated coordinates (also known as "original
coordinates", "reference coordinates", or "orcos") from and to Alembic.
A custom geometry property named "Pref" is used for (hopefully)
interoperability with Maya and Houdini. For now it's only guaranteed for
Blender-to-Blender.
Export: writing generated coordinates is optional (on by default).
Import: generated coordinates are always read whenever the reading of
vertex data is enabled.

Treat a missing <diffuse> the same as a black diffuse color.
The easiest way to see this bug is with a Collada shader like
```
<constant>
<emission>
<color sid="emission">1 0 0 1</color>
</emission>
</constant>
```
The Collada spec says this should be just
```
color = <emission>
```
ie. red everywhere. The importer slots the red into the Principled Emission socket, but since it leaves the Base Color as the default off-white, this is added to red, and the material looks white-pink in the light and red only in the shadows.
Putting black in the Base Color makes it look red everywhere.
D10939 will also eliminate the much-less-noticeable specular term for this case.

Collada shaders with black <specular> should import with Specular=0.
(A missing <specular> is the same as black.)
The general specular conversion is hard, but this case is common and easy.
Fixes the specular for all <constant>/<lambert> shaders, and <blinn>/<phong>
shaders with black/omitted <specular>. Before this they all looked too "shiny".

Before, the camera parameters were calculated only for first frame.
If the camera is animated, these values need to be recalculated in order to get the new camera view position and export the strokes as expected.
Also fixed the export of PDF when the view is not in camera view. PDF export, needs to be done in camera view.
Now the operators work like other areas of Blender using the list of selected objects.
Also, the name has been changed to:
```Layers:
- Copy Layer to Selected
- Copy All Layers to Selected
Materials:
- Copy Material to Selected
- Copy All Materials to Selected```

Export UV maps to Alembic on every frame. This makes the export of UV
maps consistent with mesh normals. In the case of static UV maps it may
cause a slight slowdown (since they're exported on every frame now), but
due to the deduplication performed by the Alembic library, the resulting
files will be the same size anyway.
Thanks to @CodyWinch for providing the solution to the problem, and
writing the original patch D8397.

While rB6b18678e34bf did the correct updates, it did it a bit early (not
covering all possible node tree changes).
Now do the ntreeUpdateTree() at the very end of the material import
instead.
