c9c2fbc52d Cleanup: IO: Use CLOG and fmtlib for tracing OBJ/PLY/STL messages
OBJ, PLY, and STL used a mix of fprintf, std::cout, and std::cerr to
trace warnings, errors, and general messages to the console.

Now, we instead use CLOG which provides real facilities for warnings and
errors and generally removes the need to pull in and use the heavy
`<iostream>` machinery.

For traces that should always be printed, `fmt::print` is used since
CLOG currently doesn't provide that particular level of trace.

Tests were only minimally changed to drop usage of streams while keeping
their prior usage of older stdio APIs. We can change to using fmtlib
there too if desired.

381898b6dc Refactor: move BLI_path_util header to C++, rename to BLI_path_utils
Move to a C++ header to allow C++ features to be used there,
use the "utils" suffix as it's preferred for new files.

4b884f737c Geometry Nodes: OBJ Import Node
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:

e955c94ed3 License Headers: Set copyright to "Blender Authors", add AUTHORS
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.

While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.

Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.

Some directories in `./intern/` have also been excluded:

- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.

An "AUTHORS" file has been added, using the chromium projects authors
file as a template.

Design task: #110784

c1bc70b711 Cleanup: Add a copyright notice to files and use SPDX format
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.

This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.

Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.

Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

4cbd799373 obj: support importing multiple files at once
Implemented the same way as STL or GPencil SVG importers: loop over
the input files, import one by one.

Has been requested by the community for quite a long time
(e.g. https://blender.community/c/rightclickselect/Jhbbbc/), as well
as 3rd party addons to implement just this
(https://github.com/p2or/blender-batch-import-wavefront-obj).

744369c114 Cleanup: move doc-strings into headers
- The comment for create_normals was moved into an inline note
  as it's not related to the public API.
- Use a colon after parameters.

e6a9b22384 OBJ: New C++ based wavefront OBJ importer
This takes state of soc-2020-io-performance branch as it was at
e9bbfd0c8c7 (2021 Oct 31), merges latest master (2022 Apr 4),
adds a bunch of tests, and fixes a bunch of stuff found by said
tests. The fixes are detailed in the differential.

Timings on my machine (Windows, VS2022 release build, AMD Ryzen
5950X 32 threads):

- Rungholt minecraft level (269MB file, 1 mesh): 54.2s -> 14.2s
  (memory usage: 7.0GB -> 1.9GB).
- Blender 3.0 splash scene: "I waited for 90 minutes and gave up"
  -> 109s. Now, this time is not great, but at least 20% of the
  time is spent assigning unique names for the imported objects
  (the scene has 24 thousand objects). This is not specific to obj
  importer, but rather a general issue across blender overall.

Test suite file updates done in Subversion tests repository.

c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

- C/C++/objc/objc++
- Python
- Shell Scripts
- CMake, GNUmakefile

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

See P2788 for the script that automated these edits.

4e44cfa3d9 Add a new C++ version of an exporter for the Wavefront .obj format.
This was originally written by Ankit Meel as a GSoC 2020 project.
Howard Trickey added some tests and made some corrections/modifications.
See D13046 for more details.

This commit inserts a new menu item into the export menu called
"Wavefront OBJ (.obj) - New".
For now the old Python exporter remains in the menu, along with
the Python importer, but we plan to remove it soon (leaving the
old addon bundled with Blender but not enabled by default).
