The main goal here is to rename things in a way that makes sense for
simulation baking, but also for the upcoming bake node.
This also removes some versioning code from 3.6 which initialized the
default bake path. Baked data from back then can't be loaded anymore
anyway, and the way the default path is generated is different now as well.

The file in question does not have the default (internal) root panel
flag for allowing child panels. This was probably saved before the flag
was added. A simple versioning snippet takes care of this case.

The hash tables and vector blenlib headers were pulling many more
headers than they actually need, including the C base math header,
our C string API header, and the StringRef header. All of this
potentially slows down compilation and polutes autocomplete
with unrelated information.
Also remove the `ListBase` constructor for `Vector`. It wasn't used
much, and making it easy to use `ListBase` isn't worth it for the
same reasons mentioned above.
It turns out a lot of files depended on indirect includes of
`BLI_string.h` and `BLI_listbase.h`, so those are fixed here.

Commit e071288ab2 do_version code was copying an allocated string from
old to new socket data, but not freeing it in the old data properly.
String can actually be moved directly from old to new data, instead of
duplicating it.
Code would not keep filedata for read libraries long enough to be able
to pass along to the 'after_liblink' versioning code. Instead, it was
passing the main file data, leading to all kind of potential breakage in
versioning code, e.g. in case of checks on available DNA data.
Fix#111776.
Also bump the recorded minimum 3.6 subversion for opening files, to
correspond to a fix in the 3.6 branch that prevents bones from seemingly
disappearing when opening files with 4.x bone collections.
`BKE_simulation_state_serialize.hh` is not necessary anymore,
because the serialization is done at a lower level.
The functionality that lived there in the past is now part of
`BKE_bake_items_serialize.hh`.
The sound equalizer is using the Audaspace FFT Convolver.
The blender part creates an array of descriptions of power per "band"
and orders the creation of Equalizer (ISound) in the Audaspace.
Modifier can be created on sound strips. It lets you define
amplification or attenuation over frequency range from 30Hz to 20 kHz.
The power is limited to -30 db - 30 db. This is done using curve
mapping widget.

Part 3/3 of #109135, #110272
Switch to new node group interfaces and deprecate old DNA and API.
This completes support for panels in node drawing and in node group
interface declarations in particular.
The new node group interface DNA and RNA code has been added in parts
1 and 2 (#110885, #110952) but has not be enabled yet. This commit
completes the integration by
* enabling the new RNA API
* using the new API in UI
* read/write new interfaces from blend files
* add versioning for backward compatibility
* add forward-compatible writing code to reconstruct old interfaces
All places accessing node group interface declarations should now be
using the new API. A runtime cache has been added that allows simple
linear access to socket inputs and outputs even when a panel hierarchy
is used.
Old DNA has been deprecated and should only be accessed for versioning
(inputs/outputs renamed to inputs_legacy/outputs_legacy to catch
errors). Versioning code ensures both backward and forward
compatibility of existing files.
The API for old interfaces is removed. The new API is very similar but
is defined on the `ntree.interface` instead of the `ntree` directly.
Breaking change notifications and detailed instructions for migrating
will be added.
A python test has been added for the node group API functions. This
includes new functionality such as creating panels and moving items
between different levels.
This patch does not yet contain panel representations in the modifier
UI. This has been tested in a separate branch and will be added with a
later PR (#108565).

Armature layers (the 32 little dots) and bone groups are replaced with
Bone Collections:
- Bone collections are stored on the armature, and have a name that is
unique within that armature.
- An armature can have an arbitrary number of bone collections (instead
of the fixed 32 layers).
- Bones can be assigned to zero or more bone collections.
- Bone collections have a visibility setting, just like objects in scene
collections.
- When a bone is in at least one collection, and all its collections in
are hidden, the bone is hidden. In other cases (in any visible
collection, or in no collection at all), the bone visibility is
determined by its own 'hidden' flag.
- For now, bone collections cannot be nested; they are a flat list just
like bone groups were. Nestability of bone collections is intended to
be implemented in a later 4.x release.
- Since bone collections are defined on the armature, they can be used
from both pose mode and edit mode.
Versioning converts bone groups and armature layers to new bone
collections. Layers that do not contain any bones are skipped. The old
data structures remain in DNA and are unaltered, for limited forward
compatibility. That way at least a save with Blender 4.0 will not
immediately erase the bone group and armature layers and their bone
assignments.
Shortcuts:
- M/Shift+M in pose/edit mode: move to collection (M) and add to
collection (shift+M). This works similar to the M/Shift+M menus for
objects & scene collections.
- Ctrl+G in pose mode shows a port of the old 'bone groups' menu. This
is likely to be removed in the near future, as the functionality
overlaps with the M/Shift+M menus.
This is the first commit of a series; the bone collections feature will
be improved before the Blender 4.0 release. See #108941 for more info.
Pull request: https://projects.blender.org/blender/blender/pulls/109976
Move control over the color of bones from bone groups to the bones
themselves. Instead of using bone groups (which are defined on the pose,
and thus owned by the object), the color is stored on:
- the bone (`struct Bone`, or RNA `armature.bones['bone_name'].color`)
- a possible override on the pose bone (`struct bPoseChannel`, or RNA
`ob.pose.bones['bone_name'].color`).
When the pose bone is set to its default color, the color is determined
by the armature bone. In armature edit mode, the armature bone colors
are always used, as then the pose data is unavailable.
Versioning code converts bone group colors to bone colors. If the
Armature has a single user, the group color is stored on the bones
directly. If it has multiple users, the group colors will be stored on
the pose bones instead.
The bone group color is not removed from DNA for forward compatibility,
that is, to avoid immediate dataloss when saving a 3.6 file with 4.0.
This is part of the replacement of bone groups & armature layers with
bone collections. See the design task at #108941.

These checks (shape keys and ID names) cost less than 1ms in Pets
production files, so think they are OK to run systematically.
The library consistency one is way more expensive (~200ms), so keeping
it behind the G_DEBUG_IO debug option for now.
NOTE: This code remains only executed in 'unlikely' case `G_DEBUG_IO` is
enabled. Think this should be systematically done, even though it can
have a non-neglectable cost... Will submit design task first though.
Add a call to `BKE_main_namemap_validate_and_fix` in the 'general
sanity validation' `after_liblink_merged_bmain_process` function.
This will detect, fix and report invalid ID naming issues (case found in
an early Gold production file).
This was hard coded to 8, which can still result in a number that
jitters making the overall FPS difficult to measure.
The default is still 8, but this is now a preference that can be
increased for values that don't jitter as much.
The `lib_link` callback cannot always be fully replaced/removed, as in
some case it is also doing some validation checks, or data editing based
on the result of lib_linking internal ID pointers.
The callback has been renamed for that purpose, from `read_lib` to
`read_after_liblink`. It is now called after all ID pointers have been
fully lib-linked for the current ID, but still before the call to
`do_versions_after_linking`.
This change should not have any behavioral effect. Although in theory
the side-effect of this commit (to split lib linking itself, and the
validation/further processing code) into two completely separated steps
could have some effects, in practice none are expected, and tests did
not show any changes in behavior either..
Part of implementing #105134: Removal of readfile's lib_link & expand code.
The `expand` callback is 'trivial' to replace, since it is only iterating
over ID pointers and calling a callback.
The only change in behavior here is that some pointers that were not
processed previously will now be.
In practice this is not expected to have any real effect (usually
the IDs used by these pointers would have been expanded through other
usages anyway). But it may solve a few corner cases, undocumented issues
though.

This is in prevision of EEVEE panoramic projection support.
EEVEE-Next is planned to add support for these parameters.
Not having these parameters in Blender DNA will make Cycles
and EEVEE not share the same parameters and will be confusing
for the user.
We handle forward compatibility by still writing the parameters
as ID properties as previous cycles versions expect.
Since this change will break the API compatibility it is crucial
to make it for the 4.0 release.

On a user level this view transform provides much better handling of colors in
the over-exposed areas.
With this configuration the following display devices are available, including
AgX view transform for them:
* sRGB
* Display P3
* Rec.1886
* Rec.2020
NOTE: There is no Filmic view transform available for the newly added display
devices.
AgX also brings an implementation of False Colors view transform, which replaces
Filmic-based, and is available for all display devices.
The backward compatibility is preserved. The new files will default to AgX view
transform, which makes it non-forward compatible.
More technical details is available in the original PR #106355.
Please note that the PR has been split into more incremental changes when
was landing.

Using this flag from linked data is always a double-edge sword, in one
end some user have been relying on it to keep around data that is not
really used as ID (like e.g. text data-blocks, node trees, see
e.g. #103687, #105687). On the other end, it often causes over-keeping
of linked data reference in production files.
From now on, when an unused linked data is to be kept around, users
should create an ID property to reference it.
Implements #106321.

Implements the paper [A Microfacet-based Hair Scattering
Model](https://onlinelibrary.wiley.com/doi/full/10.1111/cgf.14588) by
Weizhen Huang, Matthias B. Hullin and Johannes Hanika.
### Features:
- This is a far-field model, as opposed to the previous near-field
Principled Hair BSDF model. The hair is expected to be less noisy, but
lower roughness values takes longer to render due to numerical
integration along the hair width. The hair also appears to be flat when
viewed up-close.
- The longitudinal width of the scattering lobe differs along the
azimuth, providing a higher contrast compared to the evenly spread
scattering in the near-field Principled Hair BSDF model. For a more
detailed comparison, please refer to the original paper.
- Supports elliptical cross-sections, adding more realism as human hairs
are usually elliptical. The orientation of the cross-section is aligned
with the curve normal, which can be adjusted using geometry nodes.
Default is minimal twist. During sampling, light rays that hit outside
the hair width will continue propogating as if the material is
transparent.
- There is non-physical modulation factors for the first three
lobes (Reflection, Transmission, Secondary Reflection).
### Missing:
- A good default for cross-section orientation. There was an
attempt (9039f76928) to default the orientation to align with the curve
normal in the mathematical sense, but the stability (when animated) is
unclear and it would be a hassle to generalise to all curve types. After
the model is in main, we could experiment with the geometry nodes team
to see what works the best as a default.

The potential data already read in `instance_weights` listbase needs to
be freed, instead of just clearing the listbase.
Also move some (very old!) versioning code out of Particle's 'lib_link'
code into proper versioning code.
This fixes a few related issues in VSE code:
* 'lib_link' code was doing 'read_data' tasks (like cleaning up internal
runtime data).
* Handling of `SEQ_TYPE_SOUND_HD` deprecated type of strips was
extremely confusing (versioning done partly in 'lib_link' code, partly
in some 2.50 do_version code).
* Still using deprecated `SEQ_TYPE_SOUND_HD` strip type outside of
versioning code.
* Missing proper usage of deprecated `SEQ_TYPE_SOUND_HD` type inside of
versioning code (!).
Note that the actual conversion from `SEQ_TYPE_SOUND_HD` to
`SEQ_TYPE_SOUND_RAM` is now done in the 'after setup' versioning
process, where it is somewhat safer to add IDs. This implies that
`SEQ_TYPE_SOUND_HD` must be taken into account throughout the whole
regular versioning process (before and after liblink).
Conversion logic itself has been moved to the VSE code.

In a few cases (IPO conversion, Proxy conversion, ...), versioning
implies creating or removing IDs, and/or needs access to the whole Main
data-base.
So far this was done ad-hoc by adding some code at the end of
`setup_app_data`.
This commit formalizes this process by adding a BLO call
(`BLO_read_do_version_after_setup`) that will encapsulate all such
complex versioning code.
NOTE: This commit does not address the existing issue that this
versioning code is never performmed when linking new data (outside of
the 'opening a blendfile' context). This topic would require its own
design task.
NOTE: This commit does not fix the few current evil cases of ID creation in
regular versioning code. This will be addressed separately.
Although this commit does modifies slightly some logic in this specific
versioning process, no behavioral changes are expected here.

This PR adds the Lacunarity and Normalize inputs to the Noise node
similar to the Voronoi node.
The Lacunarity input controls the scale factor by which each
successive Perlin noise octave is scaled. Which was previously hard
coded to a factor of 2.
The Noise node normalizes its output to the [0, 1] range by default.
The Normalize option makes it possible for the user to disable that.
To keep the behavior consistent with past versions it is enabled by
default.
To make the aforementioned normalization control easer to implement,
the fractal noise code now accumulates signed noise and remaps the
final sum, as opposed to accumulating positive [0, 1] noise.

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.

There is no reason at all for each ID read/write callbacks to have to
deal with this generic, common data explicitely. Generic ID read/write
code is the place to handle such data (just like asset, liboverride,
etc. data are handled already).
Note behavioral change expected here.
