Due to a recent change, empty strings are unhandled. This results
in Blender crashing.
This patch fixes the crash but a discrepancy still exists...
Prior to the regression, the empty string would be replaced by the
name of the data type. This patch uses "Attribute" for the default
name regardless of type. Restoring the previous behavior would
require making and/or modifying API methods.

The Python based exporter was replacing spaces with underscores
in object/group names, mostly to handle cases where names could begin
or end with spaces. The new exporter was not doing that. Note: spaces
in material names were already handled by the new exporter.
Fixes T97769. Updated test coverage expectations; one of the test
files has an object with a space in the name.
Mask and color brushes were using the existing PBVH vertex "update tag"
to mark their modifications. This was mostly unnecessary, and causes
unnecessary calculation of normals. It also caused errors though,
because they didn't tag the corresponding PBVH node for normal
recalculation, causing problems on the borders of nodes, since one
node might accumulate into another's vertex normals, but the other
node wouldn't also accumulate and normalize the normals.
The solution is to only use the update tag for tagging deformed
vertices that need recalculated normals. Everything else is handled at
the PBVH node level (which was already the case, but it wasn't clear).
The update tag was also used for undo to tag the nodes corresponding to
changed vertices. This was wrong though, because normals and visibility
would also be recalculated for just color or mask undo steps. Instead,
just use local arrays to map from vertices to nodes.

Since 1a81d268a1, materials on object data can change during
evaluation. But a different function is necessary to retrieve materials
taking that into account.

Now when an ID template is set to an override ID, `Shift-Click` on the
right button toggles between making it user-editable (if it's a system
override), or clearing any user edit and setting it back to system override.
This loosens the current implementation a bit to only force optimal
display when editing on cage. It used to be any editing mode.
Brings GPU based subdivision closer to the CPU version.
Note that ideally, we should have a protection mechnism at global RNA
level, making e.g. any evaluated data read-only... But for now, give
better (and more consistent) protection for the collections' link/unlink
of children collections and objects.
The filter was missing in some places that are using channel data as if it was f-curve channel.
There seems to be no related issue or bug, but still it would be best to have them there.

Python based OBJ importer, as well as glTF2 importer, are creating
"placeholder" images for texture images that can't be found. These
are empty textures (displayed as magenta), but with their file paths
set so that File > External Data > Report Missing Files can report
them as missing.
Make the new C++ OBJ importer do the same as well. Fixes T99502.

Although eevee-next is disabled in Blender 3.3 there is an error that is
visible when compiling shaders using the shader builder.
This is because of an error in a preprocessing directive (defined should
be define).
This is the same principle as D15418 and D15532, but this time it's
only really needed for "IK".
Nevertheless it's probably good to add them anyway in case they get
renamed and don't share a translation with other messages somewhere
else in the code, for instance if it is decided that new constraint names
shouldn’t include spaces, like other data do.

The Python based importer had logic to immediately turn image paths
into relative-to-blender-file paths, if user preference for relative
paths is used (which is on by default). The new importer code did not
have that. Fixes T100076.
The new OBJ/MTL importer was creating a new image for any referenced
texture, even if another material (or another property of the same
material) already referenced the same texture. Make it use
BKE_image_load_exists function just like Collada or USD importers do.
Fixes T100075. Extended test coverage to count imported images;
without the fix import_cubes_with_textures_rel would have incorrectly
created 5 images instead of 4.
There's been a handful of reports where "obviously" not a UDIM filenames
were detected as such during image open.[1]
This change makes the detection less aggressive by enforcing that the
4-digit sequence be delineated on both sides by one of the following 3
characters ., -, _
This fixes the problem for such filenames as:
"screenshot-1080p.png", "Image-1920x1080.png", "(1999) Photo.png", and
"antiguaChestnut_X_1240Wx814H.png"

While this was not a critical issue (that lib pointer is only used for
some kind of sanity check that no linked data uses local ID pointers),
better to keep `IDP_BlendReadLib` in sync with all other lib-linking
code.
This reverts commit e2c02655c78b2c669468ae568ddf4b17953cc98d. It was already
reverted in the 3.2 branch, as it caused more serious issues than it solved.
Fixes T99805, T99323, T99296.
New `oldnewmap_lib_insert` does nothing special, it just wraps around existing
`oldnewmap_insert`, but it's the logical counter part of `oldnewmap_liblookup`.
It also helps tremendously when debuging complex ID pointers issues in
readfile.c code.
Crash would happen when a linked ID would become missing, that was
'pre-declared' and used only once as a 'weak link' in another library
stored before the one it came from.
In that case, the place-holder generated in read code would be freed in
`read_library_clear_weak_links`, when handling its 'owner' library, but
since all previous libraries in the list had already been 'lib_linked'
and their filedata (and related libmap) freed, the update of the libmaps
in `read_library_clear_weak_links` would not apply to data from those
previous libraries, leading to ID pointers there pointing to freed
memory.
This fix should also be backported to 2.93.
The Python based importer had a special case handling of "no faces in
the whole file at all", where it ended up treating the whole file
as essentially a point-cloud-like object (just loose vertices, no
faces or edges). The new importer code was missing this special case.
Fixes T100017. Added gtest coverage that was failing without the fix.
When plotting equally distant points around a circle support an extra
axis of symmetry so twice as many exact values are repeated than
originally added in [0], see code-comments for a detailed explanation.
Tests to ensure accuracy and exact symmetry have been added too.
Follow up on fix for T87779.

The problem was that zero-sized and non-existant attributes were
handled the same in some parts of the attribute API, which led to
unexpected behavior.
The solution is to properly differentiate the case when an attribute
does not exist and when it is just empty (because the geometry
is empty).
