Move the public functions from the editors/object (`ED_object.hh`)
header to the `blender::ed::object` namespace, and move all of the
implementation files to the namespace too. This provides better code
completion, makes it easier to use other C++ code, removes unnecessary
redundancy and verbosity from local uses of public functions, and more
cleanly separates different modules.
See the diff in `ED_object.hh` for the main renaming changes.

Previously retrieving a collection from the context like "selected_ids"
would give a linked list of allocated items. Now it returns a vector of
RNA pointers. Though the number of items is typically fairly small,
using contiguous memory and avoiding many small allocations are
typical performance improvements that could still be beneficial
when there are many items. Iteration also becomes much simpler.

The depsgraph CoW mechanism is a bit of a misnomer. It creates an
evaluated copy for data-blocks regardless of whether the copy will
actually be written to. The point is to have physical separation between
original and evaluated data. This is in contrast to the commonly used
performance improvement of keeping a user count and copying data
implicitly when it needs to be changed. In Blender code we call this
"implicit sharing" instead. Importantly, the dependency graph has no
idea about the _actual_ CoW behavior in Blender.
Renaming this functionality in the despgraph removes some of the
confusion that comes up when talking about this, and will hopefully
make the depsgraph less confusing to understand initially too. Wording
like "the evaluated copy" (as opposed to the original data-block) has
also become common anyway.

This significantly simplifies memory management, mostly by avoiding
the need to free the memory manually. It may also improve performance,
since std::string has an inline buffer that can prevent heap
allocations and it stores the size.

For some reason the "get" function actually allocates the button's
operator properties container. This may or may not make sense to
do, but while it happens, the function name might as well make
that clear.
`UUID` generally stands for "universally unique identifier". The session identifier that
we use is neither universally unique, nor does it follow the standard. Therefor, the term
"session uuid" is confusing and should be replaced.
In #116888 we briefly talked about a better name and ended up with "session uid".
The reason for "uid" instead of "id" is that the latter is a very overloaded term in Blender
already.
This patch changes all uses of "uuid" to "uid" where it's used in the context of a
"session uid". It's not always trivial to see whether a specific mention of "uuid" refers
to an actual uuid or something else. Therefore, I might have missed some renames.
I can't think of an automated way to differentiate the case.
BMesh also uses the term "uuid" sometimes in a the wrong context (e.g. `UUIDFaceStepItem`)
but there it also does not mean "session uid", so it's *not* changed by this patch.

Instead of a single function with variadic arguments, a special enum
type containing which string to request, and a special struct to
contain the request and the result, just use separate functions for
each request, and return a std::string by value. Also change the enum
item string access to just give access to the enum item itself and add
const in a few places as necessary.
The callers of the API function get much clearer this way, and it's
much easier to see which information is used to create certain tooltip
strings.
This was added at the start of the project, as a way for the source
library to control what would be overridable by the user of the data
(production files).
The implementation never went beyond the experimental area, and only
exposed in the python API then. The idea has been superseeded by the
'cherry-pick' design, so there is no point in keeping this code any
longer.
Problem is the `UI_context_active_but_get()` lookup doesn't respect menu
regions, unlike the earier call to `UI_context_active_but_prop_get()`
(which is also used to validate the existence of an active button).
Using `UI_context_active_but_get_respect_menu()` instead would work, but
in fact the earlier lookup returns the active button if any, we just
didn't use that.
Since the operator can also act on e.g theme colors [and changes to these shouldnt send undo pushes], dont do a general `OPTYPE_UNDO`, but instead be a bit more specific and only do an undo push for buttons with `UI_BUT_UNDO`.
Probably good for LTS.

Copy to selected & Alt-LMB dragging buttons didn't account for
custom properties, An IDProperty from one item was applies to other
items in the selection.
Now ID property paths are resolved up for every selected item.
Don't pass custom property names to RNA_struct_type_find_property
since this meant custom-property names could intentionally collide with
RNA property names.
This patch adds multi editing support to
FCurve modifiers using the ALT key like in the rest of Blender.
Just like object modifiers they need to be named exactly
the same and be of the same type in order for the multi editing to work.

Remove `es_ES` language.
Rename `uz_UZ` to `uz_UZ@latin`
Rename `zh_CN` to `zh_HANS`
Rename `zh_TW` to `zh_HANT`
Add support for lowercase chars in `country` part of the locale code
(although in the end it is not needed, since `boost::locale` backend
does not supports lowercase 'country' part in locales identifiers
currently) .

There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.

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.

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

In RNA collections storing ID references, the name of the collection
item may not always be unique, when several IDs from different libraries
are present.
While rare, this situation can become deadly to liboverride, by causing
random but exponential liboverride hierarchies corruptions.
This has already been alleviated by using preferably both name and index
in items lookup (a05419f18b) and by reducing the risk of name collision
in general between liboverrides and their linked reference (b9becc47de).
This commit goes further, by ensuring that references to items of RNA
collections of IDs stored in liboverride operations become completely
unambiguous. This is achieved by storing an extra pointer to the item's
ID itself, when relevant.
Lookup then requires a complete match `name + ID` to be successful,
which is guaranteed to match at most a single item in the whole RNA
collection (since RNA collection of IDs do not allow duplicates, and
the ID pointer is always unique).
Note that this ID pointer is implemented as an `std::optional` one
(either directly in C++ code, or using an new liboverride operation `flag`
in DNA). This allows to smoothly transition from existing data to the
added ID pointer info (when needed), without needing any dedicated
versioning. This solution also preserves forward compatibility as much
as possible.
It may also provide marginal performances improvements in some cases, as
looking up for ID items in RNA collections will first check for the
ID pointer, which should be faster than a string comparision.
Implements #110421.

No user visible changes expected, these are just the internal API preparations.
Modifies the Drop API for views so that tree-views can choose to insert items
before, after and into other items.
Note: While there is support for drag-tooltips that can explain how an item
will be inserted, there is no drawing yet like in the Outliner, that indicates
if an item is inserted before, after or into. There is some work on that but
that can be done separately.
Changes:
- Removes `AbstractViewDropTarget` that was shared between tree- and
grid-views, and adds `AbstractTreeViewDropTarget` and
`AbstractGridViewDropTarget`. The tree-view needs specialized handling now,
and although they could share some code still, it's not worth having another
level of inheritance.
- Modifies the drop-target API to use `DragInfo` which contains more info about
the dragging operation than just the `wmDrag`.
- Adds `determine_drop_location()` to the `DropTargetInterface` which drop
targets can use to determine when dropping means inserting before, after or
into.
- Store the block and region in the view. This is needed unfortunately but
shouldn't be an issue since the tree view is recreated on redraws, together
with the block.
- Various smaller tweaks and additions to views as needed.
TODO (outside scope of this change): Increase row height so there is no gap
between tree view items, but keep things visually the same otherwise. This
reduces flickering while dragging.
