Removal of confirmation dialogs for the following five operators. For
each of these the UI module felt that they are all either very explicit
actions and/or are easily undone.
* ARMATURE_OT_separate (Move selected bones to a separate armature)
* CURVE_OT_separate - “Move selected points to a new object”
* OBJECT_OT_vertex_parent_set (Parent selected ob to selected vertices)
* OBJECT_OT_parent_no_inverse_set (Make Parent w/o inverse correction)
* FILE_OT_directory_new - (Create New Directory)

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.

Small operator confirmations get separate confirm and cancel buttons,
better descriptions and configurable confirm button text. But still
popup at cursor location and can be cancelled with mouse movement.

There probably are more cases where crash will happen as it is
rooting into the issue with BKE_object_workob_calc_parent() which
is used in multiple places.
The issue is caused by the access to a runtime field of workob
outside of the BKE_object_workob_calc_parent(): the runtime field
is stack-allocated in the function, and can not be accessed outside
of the function.
The easiest way to reproduce is to use ASAN, and parent mesh to an
armature with automatic weights. Although, on macOS ASAN did not
report issues, so setting workob->runtime to nullptr at the end of
of the BKE_object_workob_calc_parent() was the easiest.
The solution is simple: make the function to return the matrix,
and take care of the working object inside of it, so all tricky
parts are hidden from the API.
The patch is targeting the main branch, as in 4.1 it is not
required to do such change because all uses of the function only
access object_to_world, which is stored in the object in 4.1.
A double-check in the what_does_obaction() might be needed as it
follows the similar pattern, but it does not seem that runtime
field of the workob is accessed in usages of the what_does_obaction().

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.

The `object_to_world` and `world_to_object` matrices are set during
depsgraph evaluation, calculated from the object's animated location,
rotation, scale, parenting, and constraints. It's confusing and
unnecessary to store them with the original data in DNA.
This commit moves them to `ObjectRuntime` and moves the matrices to
use the C++ `float4x4` type, giving the potential for simplified code
using the C++ abstractions. The matrices are accessible with functions
on `Object` directly since they are used so commonly. Though for write
access, directly using the runtime struct is necessary.
The inverse `world_to_object` matrix is often calculated before it's
used, even though it's calculated as part of depsgraph evaluation.
Long term we might not want to store this in `ObjectRuntime` at all,
and just calculate it on demand. Or at least we should remove the
redundant calculations. That should be done separately though.

`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.

In particular, while Object (un)linking was already tagged in relevant
BKE code, collection (un)linking was not in several cases.
This was (partially) done by user code, though almost never for the
whole hierarchy of parents.
Technically, the tag is done as part of
`collection_object_cache_free_parent_recursive`/`collection_object_cache_free`,
since currently clearing this cache is done everytime to collection
hierarchy or their content is modified.
It also removes `collection_tag_update_parent_recursive`, which was
already doing something similar, but was only called from code
adding/removing objects to collections, and was walking the same parent
hierarchy as `collection_object_cache_free_parent_recursive`.
This commit implements the decision made in #116601, to tag modified
data as close as possible from the code modifying it.
---------------------
This has an impact on deg tagging, which takes over twice as much cycles
with this commit compared to previous code when opening a Pets production
file with several liboverrides (`deggraph_id_tag_update_single_flag` goes
from less than 0.03% to over 0.06%).
The overhead remains extremely low though, and is totally unmeasurable in
global execution timing. Timing of the liboverride processing on opening
the production file also did not show any measurable differences.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
No functional changes.
Move the function ED_id_action_ensure to animrig,
and rename it to `id_action_ensure`.
This is in order to reduce references from animrig
to the editor code.

The term `looptri` was used ambiguously for both single & arrays.
The term `tri` was also used, causing `tri->tri`.
Use terms:
- `looptris` for an array or when dealing with multiple items.
- `looptri` is used when dealing with a single item.
- `lt` for a single MLoopTri variables & arguments.
This was already a convention but not followed closely.
"mesh" reads much better than "me" since "me" is a different word.
There's no reason to avoid using two more characters here. Replacing
all of these at once is better than encountering it repeatedly and
doing the same change bit by bit.
Slightly non-trivial linked collections hierarchy could cause 'Make
LibOverride' operation from 3DView fail, reporting that more than one
potential root collections were found.
Logic here was way to simple, now this error should only happen when
there are effectively more than one potential 'good' root collection
(i.e. when two unrelated collections both contain (directly or not) the
selected objects(s).
Move object runtime data to a separate header and allocate it separately
as `blender::bke::ObjectRuntime`. This is how node, mesh, curves, and
point cloud runtime data is stored.
Benefits:
- Allow using C++ types in object runtime data
- Reduce space required for Object struct in files
- Increase conceptual separation between DNA and runtime data
- Remove the need to add manual padding in runtime data
- Include runtime struct definition only in files that require it

No functional changes.
Moving the following functions
`action_fcurve_ensure` and
`action_fcurve_find`
from
`ANIM_fcurve.hh`/`fcurve.cc`
to
`ANIM_action.hh`/`action.cc`
This is an effort to ensure that the fcurve files don't need to know
about the container they are stored in so we can swap out
the container more easily.

No functional changes.
Since the following functions are now in a C++ namespace, their prefix can be removed:
* ANIM_setting_get_rna_values -> get_rna_values
* ED_action_fcurve_find -> action_fcurve_find
* ED_action_fcurve_ensure -> action_fcurve_ensure

When clearing the parent of an object that has keys,
the object position jumped back to world space immediately.
This didn't allow for keying the current position
and was inconsistent with setting a parent.
This PR fixes it by not instantly re-evaluating the animation.

Calling an API function after the node panels patch does not internally
tag the node tree with `NTREE_CHANGED_INTERFACE` any more, because the
node tree is not directly accessible from `bNodeTreeInterface`. Before
node panels the API functions for interfaces could tag the tree directly
for later update consideration, which now requires explicit tagging
calls.
The fix is to add a flag and mutex directly to `bNodeTreeInterface`, so
API methods can tag after updates. This mostly copies runtime data
concepts from `bNodeTree`. The `ensure_interface_cache` method is
equivalent to `ensure_topology_cache` and should be called before
accessing `interface_inputs` and similar cache data.
