This adds id_properties_clear() and id_properties_ensure() functions
to RNA structs. This is meant as an initial change based on discussion
in review of D9697. However, they may be useful in other situations.
The change requires refactoring the internal idproperties callback to
return a pointer to the IDProperty pointer, which actually turns out
to be quite a nice cleanup.
An id_properties attribute could be added in the future potentially.

This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,

When using the operator `ui.copy_data_path_button(full_path=True)` ({key
ctrl shift Alt C} on hover) the copied path does not consider the
library origin. That means that when there is a name clash the data path
is not accurate and refers to the local item instead.
This patch adds the library (if the ID is linked) of the returned string
from RNA_path_full_ID_py.
bpy.data.objects["Cube", "//library.blend"] instead of
bpy.data.objects["Cube"]

This patch introduces non linear sliders. That means, that the movement
of the mouse doesn't map linearly to the value of the slider.
The following changes have been made.
- Free logarithmic sliders with maximum range of (`0 <= x < inf`)
- Logarithmic sliders with correct value indication bar.
- Free cubic sliders with maximum range of (`-inf < x < inf`)
- Cubic sliders with correct value indication bar.
Cubic mapping has been added as well, because it's used for brush sizes
in other applications (Krita for e.g.).
To make a slider have a different scale type use following line in RNA:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_LOGARITHMIC);`
or:
`RNA_def_property_ui_scale_type(prop, PROP_SCALE_CUBIC);`
Test the precision, step size and soft-min if you change the scale type
of a property as it will feel very different and may need tweaking.

This flag is needed so PointerRNA structs that aren't
part of the current context can access enum values
without inspecting the context.
This is needed for keymap access, so the keymap UI and keymap
export doesn't depend on the current context.
Callbacks used in `bpy.props` didn't hold a references to the functions
they used.
While this has been the case since early 2.5x it didn't cause any
problems as long as the class held a reference.
With Python 3.10 or when using `from __future__ import annotations`,
the annotations are no longer owned by the class once evaluated.
Resolve this by holding a reference in the module, which now supports
traverse & clear callbacks so the objects are visible to Python's
garbage collector.
Also refactor storage of Python data, moving from an array into a struct.
This concerns currently only collections (`master_collection` of scenes)
and root node trees. It removes the matching type-specific helpers
(`BKE_collection_master_scene_search` and `BKE_node_tree_find_owner_ID`).
No functional change expected here.
NOTE: Current implementation of `owner_get` is far from optimal, we
could probably do it better, see {T69169}.
NOTE: While it could also have it, shapekeys IDTypeInfo was left out of
this change for now. Mainly because it sould not be used currently, and
we ultimately want to demote shape keys from ID status anyway.
Currently it is not possible to edit bare IDProperty pointer
values which are not explicitly defined through python via
UI fields. This is likely mostly because, unlike numeric values,
pointers aren't marked PROP_EDITABLE by default. However there
are also some bugs in the RNA code that need fixing.
The Geometry Nodes modifier uses bare properties to store
input settings for the node group it wraps, so supporting
Object and Collection sockets requires editable pointers.
This patch marks bare IDProperties editable, and ensures
that changing ID pointers rebuilds the dependency graph.
A type check is needed because an IDPROPERTY PointerPropertyRNA
can actually wrap a group value rather than an ID pointer.
Making pointers editable is not likely to accidentally
affect UI fields that were not intended to be editable,
because a simple `layout.prop` cannot determine which
datablocks to display in the menu and remains read-only.
The PROP_NEVER_UNLINK flag is also removed: it seems it
was added because the edit field that couldn't produce
a menu to set the pointer used to still display the unlink
button, but that seems not to be the case anymore.
Actual support for Object & Collection inputs in the modifier
is added in D10056, which can be used to test this code.

The rna_idproperty_check call should be done before accessing
the prop pointer so that it can detect IDProperty values and
replace them with the actual PointerPropertyRNA object.

We have to check that the RNAProperty found in `rna_idp_path` from the
currently checked IDProperty name is actually a real runtime RNA-defined
one, and not a static C-defined RNAProperty...
Remove DNA headers, using forward declarations where possible.
Also removed duplicate header, header including it's self

This is the initial merge from the geometry-nodes branch.

* 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 was reported in the form of the eyedropper of the 'Parent' property
creating a custom property 'parent' if self was picked.
Problem arises when certain checks for setting rna pointer properties
failed (for example: the PROP_ID_SELF_CHECK check) and then a different
code path was entered (which was only meant for IDProperties).
Problem was introduced in rBa7b3047cefcb.
To solve, now first enter the branch for rna-based pointer properties,
then perform the sanity-checks (and if these fail: dont enter the other
unrelated codepath but instead do nothing)

Collections of liboverride data only support insertion of new items (and
deleting or moving those around). No operation on existing items from linked
data is allowed.
Reflect that in RNA functions used to edit py-defined RNA collections.
Note that this is not ideal currently, it does the job but feedback to
user is rather poor. Ideally add-ons should implement higher-level
checks for override cases in their operators.
The triplet static RNA / runtime RNA / custom properties is a real pain to
deal with...
Using the new `PropertyRNAOrID` struct helps clarifying and properly
dealing with all three cases.
Note that this makes override of py-defined RNA properties working
(support for that will be committed next).

Introduce new PropertyRNAOrID structure, storing most useful data about
an 'opaque' PropertyRNA in relation with a given PointerRNA struct.
It deals with all the three cases (pure static RNA, runtime RNA where
data is actually stored in IDProperties, and pure IDProperties, aka
custom data.
