Previously, `frame_key_at` would return `-1` for when it couldn't find
a key for the given frame.
This could lead to issues though, because `-1` is a valid key (it is a valid scene frame number).
This changes the API to return an optional instead. This makes it very clear
when no key was found, and should make it less error prone.
The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

When using the MapUV node for certain NPR workflows (for example palette
based remapping of colors) it can be useful to not use the default
anisotropic filtering.
In preparation of potentially adding more filter modes at a later stage
and to keep things consistent with the 'transform' node we use the full
set of interpolation modes in the enum, but expose only the implemented
ones in RNA..
This has been broken since 2.8.
The highlevel reason for this is that the "info file" (saved as frame
zero) was not written anymore.
Reason for that in turn is that when calling `BKE_ptcache_write` outside
the bake job, the `PTCacheID` `calldata` (a psys in our case) is not the
evaluated particle system, causing a check for `totpoint` to fail (these
were always zero).
Deeper reasoning is unclear, no further investigations were done as to
why/when this happened.
The solution proposed here is using the evaluated psys when writing the
info frame (and this is isolated to just this spot). File then gets
written and can/will be read when using this as an external disk cache
in another file.

This was caused by the introduction of the generic `SocketValueVariant` type.
Now it's not enough to simply default-construct the value anymore, but it has
to be constructed with the correct type.
This allows modifiers to have cache pointers that are preserved over undo steps.
I intend to use this for the baked data cache for the geometry nodes modifier.

The name `offset_in_ID` is very misleading since it does not have to be an offset at all,
it just has to be some unique value. Often it's also a hash or a constant value depending
on the use.

When there is no default color attribute yet, when creating a new color
attribute with the store named attribute node, set the default. Though
we generally try to avoid this more magical behavior, there's little
downside in this case, and it's probably what users expect.
Don't set the active attribute though, since that's UI data that generally
shouldn't be changed procedurally. It's okay if there's no active color
attribute.

The function for retrieving a shape key by its index is named
somewhat confusingly, and effectively reimplements BLI_findlink.
However, more importantly, for some reason it is coded to return
null for the index 0 instead of the basis shape key. This severely
limits its usability in some cases.
This refactor replaces the function with a simple strongly typed
wrapper around BLI_findlink, using a different name, and updating
the call sites to check that the index is not 0 where necessary.
The FPS menu was using a cached value which wasn't being refreshed
when translation changed.
Add `bpy.app.handlers.translation_update_post` handler which runs
when translation changes, this can be used to clear any cached UI
values.

We don't actually protect against interface sockets with empty
names elsewhere. This assert was triggered when trying to group
a `Bake` node, because it tried to create an interface socket of
the extend socket. This case is handled by the check below.
This adds a cache to read a normal vector for a plane that (roughly) fits a curve.
If the curve lies on a plane, the vector always point along this plane normal, otherwise it's an approximation.
The cache is lazily calculated and invalidated when the positions are tagged for a change.
This allows code outside of the render pipeline to make proper
decisions about how the imbuf of render passes are to be handled.
For example, IMB_create_gpu_texture() will now properly select
single channel grayscale texture format for depth pass coming from
multilayer EXR, additionally solving assert in the GPU compositor
code which verifies expected and actual imbuf texture format.

Loading pre-4.0.20 node groups with sockets using subtypes causes
broken socket identifiers. This is because the node tree interface now
expects sockets to use the base identifiers ("NodeSocketFloat" instead
of "NodeSocketFloatFactor" etc.).
To correct this the conversion code now replaces socket idnames that
include a subtype suffix with their base names. This fix is also applied
to files between versions 4.0.20 and 4.1.10, where the socket types
may have been converted incorrectly.

Add `ATTR_WARN_UNUSED_RESULT` to the
`BKE_animsys_eval_context_construct` and
`BKE_animsys_eval_context_construct_at` functions. They are pure
functions, and without using their returned value they are pointless.
No functional changes.
Sharing of the normals cache between copied meshes was missing from
89e3ba4e25, which under-represented the benefits of the
change. In a simple file where geometry nodes causes a re-evaluation
without changing the normals, this increased FPS from 2.6 to 14.
After the replacement of auto smooth with a modifier, sharp edges are
always used, so the "shade smooth", "shade flat", and "smooth by angle"
operators cleared the attribute. However, often users spend significant
time manually tagging edges sharp, and the operators make it too easy to
lose that data.
To keep the old behavior by default, add an option called "Keep Sharp
Edges". Though this can make the operators "ineffective" at their goal
of changing the way the meshes look, or result in redundant data stored
on the mesh, it's a much safer default, especially as users get used to
the new workflow.
