followup to 815ca2310f, this one fixes the RNA_MeshLoopColor case, adds
RNA_VertexGroupElement and RNA_LatticePoint.
coop with @sergey, thx.
Fixes T68666
The static mesh issue described in T65816 has been resolved by @Sergey
in T60094.
This commit fixes the last bit of the puzzle, which was two-fold:
- A missing depsgraph update when setting `orig_object.data = new_mesh`
from Python. Thanks @Sergey for providing the fix :)
- Properly locking the interface while exporting. This prevents crashes
as described in T60094. The previous approach of calling
`BKE_spacedata_draw_locks()` was not enough.
This allows accessing it from drivers and using it in UI, as
demonstrated by adding it to the transform panel of 3D View.
As an aside, properly mark transform-related properties of Bone
read-only, as they can only be changed correctly in edit mode.
Allows to access dependency graphs created for render engines
to inform them about changes in .blend file structure from the
Python handlers.

Currently unused, but will allow to keep of an owner of the depsgraph.
Could also simplify other APIs in the future by avoiding to pass bmain
explicitly to relation update functions and things like that.
This partially reverts commit 0b2d1badec
Post increment can deep-copy for C++ iterators, while in my own checks
GCC was able to optimize this to get the same output,
better follow C++ best practice and use pre-increment for iterators.
The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

In some rare cases it is convenient to store a short array value
as a custom property, e.g. a vector or color. For example, it may
be helpful when importing/exporting certain formats that support
custom or nonstandard attributes on objects.
The custom property storage already can handle arrays in order to
support properties defined via python. The only thing missing is
UI support (and some bugs), and this patch fixes that:
- Allow editing short array properties via Custom Properties panel.
- Fix a UI layout sizing bug triggered by the previous item.
- Fix a dependency graph bug with drivers using such properties.
- Make RNA_*_get_default_array code robust in case of size mismatch.
- Support custom default values for array properties, allowing
both an array and a scalar value.

Such reload can no longer happen directly and is to be done via dependency
graph.
Eventually, the movie cache will become shared across all copies of the
clip, but even then we still need to have dependency graph mechanism because
we need to update FFmpeg animation handle (which can not be shared across
the copies).
The issue was caused by dependency graph always ignoring animation
update when it is first time constructed. This was a way to make it
preserve unkeyed changes on undo/redo. This, however, made it so
changes of animation data itself (such as deleting/moving keyframes)
did not trigger animation update by the dependency graph.
This worked prior to copy-on-write because animation recalc flags
were stored in the DNA and never re-set on file/undo load. This was
giving dependency graph a clue that animation is to be re-evaluated
when operator explicitly asked to (more precisely, when such operator
was undone/redone).
This change makes it so original ID's recalc flags are storing
recalc flags when ID is tagged for update as an response to user
input. This way re-building dependency graph can force animation
to be updated on redo.
Tricky part here is that ID's recalc flag is no longer to be zeroed
when loading undo step (which is the same as reading .blend file).
This is something what works differently comparing to legacy
dependency graph, which was zeroing object's recalc flags there but
not animation data's recalc flags.
Shouldn't be causing issues, since unkeyed changes are not preserved
upon opening a file anyway, at least to my knowledge.
Related reports which are to be taken into account and verified
they are not re-introduced when making changes in the area:

- T54296: Cycles viewport render stuck on constant re-render

Current frame is stored in a scene, and scene might have multiple view
layers. The inactive view layers were not informed about scene's frame
being changed, so when user switched back to view after changing scene
frame it was in an inconsistent state between current scene frame and
animation.
Now we tag scene for time changes, so dependency graph can catch up
and do proper update.
Currently tagging is from quite generic place. Probably better approach
would be to tag from where frame is actually being assigned. Downside
of this is that it's easy to miss some places.

There are two aspects to the problem:
- Dependency graph update for compositor preview was missing
updates flush.
Apparently, update for new frame style of update will take
care of flushing, but not the update tagged style of update.
This goes to a legacy dependency graph and is to be changed
at some point, but not so close to the release.
- Movie clips were missing from the compositor dependency graph.
This fixes part of T66519.

The issue was caused by modifications to planar track tagging clip for
copy-on-write, which was invalidating its cache and forcing current
frame in 3D viewport to be re-load.
Ideal solution would be to share movie cache across original and
evaluated movie clips which will reduce memory usage. However, doing
such ownership changes so close to the code freeze is not something
comfortable to do.
Make sure particle system edit never points to a modifier or particle system
which becomes inactive.
This is needed because copy-on-write will change pointers of them and those
pointers are supposed to be restored from particle system evaluation. But
since the particle system is disabled it never updates pointers.

The root of the issue comes to the fact that part of dependency graph
is being removed, without doing any further remapping.
This was happening because only materials used by objects were pulled
in, so when material mode is changed some material became unused and
removed from the dependency graph and freed, causing object or its
data to point to a freed memory in its materials array.
Simplest and safest way to solve this is to pull materials referenced
by both object and object data. This causes somewhat higher memory
usage but keeps evaluated state of scene in an always consistent state,
without any need to tag/update object's data on material mode change.
Don't think it is a problem in practice.

Two issues here:
- Evaluated object data is to only be updated for selection only after modifier
stack is done its job. Otherwise it's possible to have selection batch update
called on an input data, at the same time as original object data is being
evaluated.
- If object's modifier stack did not create its own evaluated mesh (in case
when there is no effective modifiers, for example) can not update selection
on object's data, as it might cause threading issues between objects sharing
same data.
