- Pass Span by value. It is a small struct, and passed by reference
it acts as a pointer to a pointer.
- Remove unnecessary `= {}`. Vector has a default constructor.
- Use initializer list Span constructor to avoid temporary array.

Batch deletion of IDs could lead to deleting ObData ones while keeping
the related ShapeKeys.
Orphaned shape keys are not allowed anymore in Blender, they are checked
against in both file write and read code.
This would lead to assert (and crash) e.g. in the liboverride code.
This commit forcefully add shapekeys of deleted meshes, curves etc.,
when calling e.g. `BKE_id_multi_tagged_delete`.
Note that deleting the shapekey when deleting the obdata ID was already
implemented in single ID deletion (`BKE_id_delete` & co), in the
underlying private `id_free`. But this is skipped in `no main` case.
which is used by the batch deletion code for performance optimizations.
This is a nasty gathering of several issues, main one being that 'local
collections' of 3DViews are still updated immediately instead of the
deferred update used for all other viewlayer cases.
The change in a16bcb6576 led to internal references to the Scene's
master collection to become invalid, which is the expected behavior.
But this turns the Scene's view_layers into invalid state too.
Ideally, there should never be resync of viewlayers of a scene being
deleted anyways.
For now, take the (hopefully!) safe approach of explicitely forbidding
any viewlayer update during ID deletion process, and deferring it at the
end of the process.
Note that this change may also give some marginal gerformance
improvements in some rare edge cases (like deleting a very heavy scene
with many collections and 'local collection' 3DViews ?).
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.
Also see #103343.
Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.
