The meshes custom data-mask edit-mode check only considered the object
in edit-mode if it was the active object. This isn't correct as multiple
objects can be in edit-mode at once.
The potential for `mesh_get_eval_deform` to leak memory remains,
this just avoids an unnecessary mesh re-generation on selection
(which was causing the leak), see: !128228 for details.
Fixes incorrect usage of StringRef in new grease pencil code, where
`.data()` was passed as a null terminated C string. Removes the now
unnecessary `std::string` creation that attribute accessors used to
fix that problem.

Remove the indirection previously used for the topology refiner
to separate C and C++ code. Instead retrieve the base level in
calling code and call opensubdiv API functions directly. This
avoids copying arrays of mesh indices and should reduce
function call overhead since index retrieval can now be inlined.
It also lets us remove a lot of boilerplate shim code.
The downside is increased need for WITH_OPENSUBDIV defines
in various parts of blenkernel, but I think that is required to avoid
the previous indirection and have the kernel deal with OpenSubdiv
more directly.

`BKE_animdata_fix_paths_remove()` now calls into the new function
`animrig::legacy::action_fcurves_remove()`, which works for both
legacy and slotted Actions.
Also I updated the documentation of the BKE function so that it's clear
what it's actually doing.
No functional changes for legacy Actions.

Reduce cognitive complexity of `BKE_animdata_fix_paths_remove()` by
returning early, returning literals (instead of variables) when the
returned value is known, and just calling `BKE_animdata_from_id()` instead
of re-implementing it here.
No functional changes.
When assigning an Action with the new API:
- check the Actions ID type (if it is a legacy Action), and
- check whether the ID is in NLA tweak mode.
This means that action assignment can fail, so the
`animrig::assign_action()` and `animrig::unassign_action()` functions
now return a `[[nodiscard]] bool`.
Part of `generic_assign_action()` has now also been shielded with an
`#ifdef WITH_ANIM_BAKLAVA` just to be sure.
This also includes a change in `BKE_animdata_free()`. That function now
first exits NLA tweak mode (if enabled) before freeing the Actions. This
makes it possible to simply un-assign the assigned Action, as all the
NLA tweakmode stuff has already been taken care of by the responsible
function.

This patch improves working with grease pencil layers in geometry nodes.
* Allow layers to have duplicate names in geometry nodes. In original data, unique names are enforced.
* This allows e.g. duplicating layers and then merging them by name in the end.
* It also resolves a big serial bottleneck when working with many grease pencil layers in geometry nodes. Enforcing unique names is inefficient.
* New `Merge Layers` node that can merge multiple layers by name or by a custom group id.
* Applying a grease pencil modifier now first merges all layers with the same name to ensure all names are unique.

There were multiple issues that popped up when following the reproduction steps
in the report:
* Somehow, `socket.socket_data` was set for a custom socket type. I don't know
how that happened yet. I added some code to clean it up on file-load.
* `declaration_for_interface_socket` did not work yet when the socket type is
not registered. Now it just creates a custom socket with the correct idname,
even if that's not registered yet.
* There was a missing node tree update when changing `bl_socket_idname` of
interface sockets.

The material handling on curves was not super strong yet because there was not a
lot of need for it. However, now with Grease Pencil it's much more likely that
material selections are used on curves.
The patch is larger than one might expect at first, because we have to pass more
information into the field context in many places, because the materials are
stored on `Curves` and not `CurvesGeometry`.
Related to #128109.

The issue has been introduced in aca27e5462.
Before that change the memory used for baking was cleared-alloced,
but now it relies on the default object initialization. This could
leave fields uninitialized.

Previously we were using a bespoke hodgepodge of
`Action::is_action_legacy()` and `Action::is_action_layered()`,
sometimes in combination with checking for the Baklava feature flag,
when what we really meant is "Should this action be treated as legacy
or not?"
This commit changes the places where that's semantically what we meant
to use `action_treat_as_legacy()`. Some of those places were already
correct, using a compound conditional, but some of them weren't, and
thus were not always branching correctly. For those latter cases,
this commit is a bug fix.
Importantly, not all uses of bare `Action::is_action_legacy()` or
`Action::is_action_layered()` are semantically incorrect: there are many
places where that is the right thing to do. This commit takes care not
to touch those places.

This improve the API in multiple aspects:
* No need for an additional `lookup` call to get the current attribute. This
would internally iterate over all attributes again. This leads to O(n^2)
behavior. Note that there are still other reasons for O(n^2) behavior when
processing attributes (where n is the number of attributes).
* Remove the need to return a value from the iteration code to indicate that the
iteration should continue. This is now the default behavior. The iteration can
still be stopped by calling `iter.stop()`.
* Easier access to `is_builtin` property.
* Iterator callback only has a single parameter instead of two (of which one is
sometimes unused).

This bug was introduced in #126561. The issue was that the UI action
selectors no longer ensured that animdata existed before attempting
to assign an action, which would then cause the assignment to fail.
However, this was only the case in Blender builds without experimental
features, since the new Baklava code paths would otherwise be taken,
which *do* handle this correctly.
This fixes the issue by ensuring animdata in the non-experimental code
paths again.

Previous fix (b17734598d) tried to fix this, but it seems that
depending on CPU and video width, ffmpeg might need at least 64
byte alignment, even if CPU we're running on is only AVX2 (32 byte
alignment). That is because some other parts of ffmpeg code
statically pick 64 or 32 byte alignment internally, depending on whether
AVX512 support is even compiled in (even if CPU might not have it).
I have checked whether this does not negatively affect a platform where
SIMD alignment is always 16 (Mac), and it does not, everything works as
expected.

Currently we allow the before/after meshes to have different
sets of attributes. But then we compare all attributes in each
mesh anyway, regardless of whether they exist or not.
When the PBVH is rebuilt, the `active_face_index` and
`active_grid_index` fields are initialized to -1. This results in a
possible segmentation fault if the `active_face_set_get` method is
called without these fields being populated.
This commit switches the raw `int` usage for `std::optional` to
better communicate the intent of these fields.

Adds support for the "Menu" socket type in for-each-element zones. This
only includes field inputs and their matching per-element values, but
not outputting attributes of type Menu (Menu attributes are not
generally supported at this point).
A dedicated enum propagation function is added for the zone input node.
This isn't technically necessary: the first 2 inputs and outputs should
be ignored but are not menus anyway. However, this is clearer and
provides a place for future changes.

Add slotted/layered Action support to `get_active_actiongroup()` and
`set_active_action_group()`.
Note that there is still a bunch of code around that directly manipulates
the action group flags, instead of using these functions. That's for
another commit to address.
This commit also introduces the functions `action_treat_as_legacy()` and
`channel_groups_all(action)` utility functions in the `animrig::legacy`
namespace.

For most cases where the iteration index is needed, a For Each zone is the
better than using a Repeat zone. It's easier to use and more optimizable.
However, in some cases a Repeat zone is actually the right solution and the
index often useful in such cases too.

It is too easy to accidentally enable skipping the simulation while moving the
node around without noticing. Now it is necessary to pass in a boolean value
from another node to modify the skip value. Existing files that had this
checkbox checked are updated by versioning code.
This implements #127506.

Convert the Grease Pencil legacy converter code to the new layered
Action API.
Unfortunately this cannot just work on legacy Actions (and then rely on
the versioning to layered Actions we'll land soon), as the GP conversion
runs as the final step of the versioning process. This cannot be helped,
as the usual versioning is not allowed to create new IDs and this does.

Supporting selection operators and overlays in sculpt mode is necessary
to support masking operations.
This enables selection drawing in the overlay in sculpt mode,
and ensures all the necessary operators (pick, lasso, circle, box)
handle the differences in modes correctly.
The selection code so far was expecting object mode, so the `vc->obedit`
object was used without further checks. Now the selection code can be
called outside of edit mode, in which case the `vc->obact` object must
be used instead. Similarly edit mode and sculpt mode have separate
`selectmode` flags, so the correct mode property must be used from the
tool settings depending on the object mode. These changes require some
refactoring of unrelated selection code.

When building proxies at lower than 100% resolution, the video frame
downscaling step was single threaded, as found via #127956.
Make it use the same threaded sws_scale machinery that the usual video
decoding/encoding uses. Video encoding/decoding was only using it for
RGB<->YUV conversions, so source and destination sizes were always matching;
here it needs to have different source and destination sizes though.
Time taken to rebuild 50% proxy for a 4K resolution 1440 frames (1 minute)
long video file, on Ryzen 5950X (Win10/VS2022):
- Blender 4.2: 20.1 sec, CPU usage 30-40%.
- Blender 4.3 main: 13.1 sec (ffmpeg build has been fixed to use SIMD),
CPU usage still 30-40% though.
- This PR: 8.3 sec, CPU usage ~95%.
