Use a consistent style for declaring the names of struct members
in their declarations. Note that this convention was already used in
many places but not everywhere.
Remove spaces around the text (matching commented arguments) with

This is mostly a cleanup to avoid hardcoding the eager calculation of
normals it isn't necessary, by reducing calls to `BKE_mesh_calc_normals`
and by removing calls to `BKE_mesh_normals_tag_dirty` when the mesh
is newly created and already has dirty normals anyway. This reduces
boilerplate code and makes the "dirty by default" state more clear.
Any regressions from this commit should be easy to fix, though the
lazy calculation is solid enough that none are expected.
Currently there is a "calc_face_normal" argument to mesh to bmesh
conversion, but vertex normals had always implicitly inherited whatever
dirty state the mesh input's vertex normals were in. Probably they were
most often assumed to not be dirty, but this was never really correct in
the general case.
Ever since the refactor to move vertex normals out of mesh vertices,
cfa53e0fbe, the copying logic has been explicit: copy the
normals when they are not dirty. But it turns out that more control is
needed, and sometimes normals should be calculated for the resulting
BMesh.
This commit adds an option to the conversion to calculate vertex
normals, true by default. In almost all places except the decimate
and edge split modifiers, I just copied the value of the
"calc_face_normals" argument.

So far it was needed to declare a new RNA struct to `RNA_access.h` manually.
Since 9b298cf3db we generate a `RNA_prototypes.h` for RNA property
declarations. Now this also includes the RNA struct declarations, so they don't
have to be added manually anymore.

Ref D14069
This is similar to e032ca2e25 which removed the
callback for volumes. Now that we have geometry sets, there is
no need to define a callback for every data type, and this wasn't
used. Procedural curves/hair editing will use nodes rather than new
modifier types anyway.
This allows us to remove a callback from the modifier type info struct.
In the future the these modifiers might just be replaced by nodes
internally anyway, but in the meantime it's nice to unify the handling
of evaluated geometry a bit.

Since the initial merge of the geometry nodes project, the modifyPointCloud
function already was already modifying a geometry set. The function wasn't
renamed back then, because then the merge would have touched many
more files.
Ref T83357.
This is the initial merge from the geometry-nodes branch.
Nodes:
* Attribute Math
* Boolean
* Edge Split
* Float Compare
* Object Info
* Point Distribute
* Point Instance
* Random Attribute
* Random Float
* Subdivision Surface
* Transform
* Triangulate
It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier.
Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.
It includes commits from:
* Dalai Felinto
* Hans Goudey
* Jacques Lucke
* Léo Depoix
This removes `foreachObjectLink` from `ModifierTypeInfo`, `GpencilModifierTypeInfo`

As noted in T80164, there are quite a few area of Blender where the
"Reset to Default Value" operator in button context menus doesn't work.
Modifiers are one of them, because the DNA defaults system was never
set up for them.
Additionally, this should make modifier versioning easier. Whenever a
new field is added it should be automatically initialized to the
default value.
I had to make some ordering changes in the following modifiers to work
around an error with `-Wsign-conversion` in the macros:
- Solidify Modifier
- Corrective Smooth Modifier
- Screw Modifier
Some modifiers are special cases and are skipped in this commit:
- Data Transfer Modifier
- Cloth Modifier
- Fluid Modifier
- Softbody Modifier

For modifier shortcuts we added a "custom_data" field to panels.
This commit uses the same system for accessing the list data that
corresponds to each panel. This way the context is only used once
and the modifier for each panel can be accessed more easily later.
This ends up being mostly a cleanup commit with a few small changes
in interface_panel.c. The large changes in the UI functions are due
to the fact that the panel custom data is now passed around as a
single pointer instead of being created again for every panel.
The list_index variable in Panel.runtime is removed as it's now
unnecessary.

This is part of a greater blenloader decentralization effort (T76372).
For modifiers the goal is that fewer files have to be modified when
a new modifier is added.
This patch just adds the `blendWrite` and `blendRead` callbacks to
`ModifierTypeInfo` but does not change any other code yet. In the next
steps, modifier specific code will be moved from `writefile.c` and
`readfile.c` into their corresponding `MOD_*` files.
This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.
This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.
These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.
Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.
However, the large number of UI changes in this patch may mean
that additional polishing is required in master.
Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

Modifier stack evaluation would copy mesh settings other than mesh topology
automatically, outside of the individual modifier evaluation. This leads to hard
to understand code, and makes it unclear which settings are available in following
modifiers, and which only after the entire stack is evaluated.
Now every modifier is responsible to ensure the mesh it outputs preserves materials,
texture space and other settings, or alters them as needed.

The general idea of this change is to have a runtime data pointer
in the ModifierData, so it can be preserved through copy-on-write
updates by the dependency graph.
This is where subdivision surface modifier can store its topology
cache, so it is not getting trashed on every copy-on-write which
is happening when moving a vertex.
Similar mechanism should be used by multiresolution, dynamic paint
and some other modifiers which cache evaluated data.
This fixes T61746.
Thing to keep in mind, that there are more reports about slow
subdivision surface in the tracker, but that boils down to the
fact that those have a lot of extraordinary vertices, and hence
a lot slower to evaluated topology.
Other thing is, this speeds up oeprations which doesn't change
topology (i.e. moving vertices).

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

See P901 for script to perform these edits.
Add special handling for both edge cases (:p):
* 180° is same as no splitting by angle;
* 0° is same as split on all edges unconditionnaly.
In both cases we can also avoid computing poly normals.
