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

b220ec27d7 Cycles: Update Velvet BSDF to Sheen BSDF with new Microfiber sheen model
This patch extends the old Velvet BSDF node with a new shading model,
and renames it to Sheen BSDF accordingly.

The old model is still available, but new nodes now default to the
"Microfiber" model, which is an implementation of
https://tizianzeltner.com/projects/Zeltner2022Practical/.

f3cb157452 Compositor: add new node: Kuwahara filter
The filter is used to reduce noise while preserving edges. It can be used to create a cartoon effect from photorealistic images.

It offers two variations:
1) Classic aka isotropic kuwahara filter: simple and faster computation. Algorithm splits an area around a single pixel in four parts and computes the mean of the region with the lowest standard deviation.
2) Anisotropic Kuwahara filter: improves the classical approach by considering the direction of structures of regions

This patch implements both approaches above as multi-threaded operations for the full-frame and tiled compositor.

8cde7d8f8a Cycles: Merge Anisotropic BSDF node into Glossy BSDF node
Used to be https://archive.blender.org/developer/D17123.

Internally these are already using the same code path anyways, there's no point in maintaining two distinct nodes.

The obvious approach would be to add Anisotropy controls to the Glossy BSDF node and remove the Anisotropic BSDF node. However, that would break forward compability, since older Blender versions don't know how to handle the Anisotropy input on the Glossy BSDF node.

Therefore, this commit technically removes the Glossy BSDF node, uses versioning to replace them with an Anisotropic BSDF node, and renames that node to "Glossy BSDF".

That way, when you open a new file in an older version, all the nodes show up as Anisotropic BSDF nodes and render correctly.

This is a bit ugly internally since we need to preserve the old `idname` which now no longer matches the UI name, but that's not too bad.

Also removes the "Sharp" distribution option and replaces it with GGX, sets Roughness to zero and disconnects any input to the Roughness socket.

03806d0b67 Re-design of submodules used in blender.git
This commit implements described in the #104573.

The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).

This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.

This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale

This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.

Running `make update` will initialize the local checkout to the changed
repository configuration.

Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
