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
e9bbfd0c8c (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).
