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
Ref !110783.
Previously, there were two independent algorithms for analysing how anonymous
attributes are used in a node tree: One that just computed the `aal::RelationsInNode`
for an entire node tree and one that performed a more in depth analysis to
determine how far anonymous attributes should be propagated.
As it turns out, both operations can also be done at the same time and the result
can be cached on the node tree. This reduces the amount of code and allows for
better code reuse.
This simplification is likely only an intermediate step as things will probably have
to be refactored further to support e.g. serial loops (#108896).
