Adds support of NURBS weights or "rat bspline" in OBJ terms.
Tries to guess Blender knot mode better:
- Detects and closes loops. This decision is based on geometry only. No metadata is provided in OBJ for this, so importer has checkbox to disable this feature.
- Bezier knot mode allows to import circles and circular arcs.

Add a node similar to the STL import node (d1455c4138) that
imports OBJ files, including both meshes and curves. The output consists
of a geometry instance for each mesh/curve in the file.
There are a few improvements to address in the future: Currently the node
has no inputs besides the file path. Options may be exposed in the future.
Materials are also not imported yet, because creating material data-blocks
during evaluation may not be trivial.
This is part of a GSoC project:

When moving importers from Python to C++ validation was removed
(from PLY) & disabled by default (STL & OBJ) which re-introduces
crashes reported by users such as #31835.
Enable validation by default because crashes caused by imported data
should be avoided, especially since the crashes may happen later when
users enter edit-mode or run certain editing operations.
This does slow down importing, from testing a 236MB .OBJ it takes around
twice as long to import (~1.5 to ~3 seconds). Although validation can
be optimized to reduce the overhead ad well as run in parallel for
importers that load multiple objects.
The defaults for USD and Alembic remain unchanged since this was never
enabled by default, although we could consider enabling these as well.
This implements the ability to have file exporters added and configured on Collections.
Exporting is reachable from several locations:
- Individually on each exporter configuration: The `Export` button in each panel header
- For all exporters on the collection: The `Export All` button in the main panel interface
- For all exporters on all collections in the scene: The `File`->`Export All Collections` button
Visibility of which collections currently have exporters configured is done by ways of an icon added to the Collection row in the Outliner.
Adding multiple exporters for the same file type is permitted. The user is free to setup several exports of the same format but with different file locations or settings etc.
Notes:
Only USD and Wavefront OBJ are enabled for the initial commit. Additional formats, including those implemented in Python will be added as separate commits after this.

Reduce dependence on Blender headers as much as possible and move closer
to an include-what-you-use setup.
- Removes unnecessary includes
- Replaces some includes with more appropriate, narrower, substitutes
Pull Request: https://projects.blender.org/blender/blender/pulls/119234
Properly handle exceptions from STL and PLY code to prevent crashes on
invalid file paths.
This will now also Report errors/warnings to the callers of these
formats as well. For the UI this means a Report banner and Info editor
entry. For Python scripts this means an exception instead of silently
continuing.

Pull Request: https://projects.blender.org/blender/blender/pulls/118731
Implements #105001 - new import option for name separator, e.g. "|" or "/".
Names found in the OBJ file are split by that, and a Collection hierarchy is
made, so you can have e.g. "o House/Roof/Tile" in the OBJ file.

This reverts commit 074dbf08cd.
This change caused PLY and OBJ tests not to compile,
even with the identifiers updated some OBJ tests fails
with different rotation values.
This helps to document standard behavior, improves type
safety, reduces code duplication, and gets us closer to being
able to remove some of the older C math API.
