Fix T89851: Geometry nodes: wrongly detected "Node group has unidentified
nodes or sockets" error

rBfe22635bf664 introduced a utility to check for this (but it was always
returning true).

This wasnt a problem in master (since it is unused there), but in the
2.93 branch, this utility is actually used and the error results in all
geometry nodetrees to appear with the "Node group has unidentified nodes
or sockets" message (and being unusable).

Now return false in has_undefined_nodes_or_sockets if all nodes and
sockets have been successfully checked.

This commit then needs to end up in the 2.93 branch.

LineArt: Fix crash due to empty duplicollection.

Fix T89455: Cycles crash when rendering a Mesh with autosmooth

The crash was caused by a mistake in 5f9677fe0c533b008b815d7fee0b56509a414ab7
where the pointers to the custom data layers would be overwritten with the one
for the first layer, as CustomData_duplicate_referenced_layer is only about the
first layer. customData_duplicate_referenced_layer_index should be used instead
to duplicate the right layer.

Fix T88756: crash when baking with autosmooth

When baking some data, we create a new Mesh with edits and modifiers applied.
However, in some cases (e.g. when there is no modifier), the returned Mesh is
actually referencing the original one and its data layers. When autosmooth is
enabled we also split the Mesh. However, since the new Mesh is referencing the
original one, although `BKE_mesh_split_faces` is creating new vertices and edges,
the reallocation of the custom data layers is preempted because of the
reference, so adding the new vertices and edges overwrites valid data

To fix this we duplicate referenced layers before splitting the faces.

Fix T88015: Round end caps on Freestyle lines not shaped as documented

This might be an artistic choice, but round end caps are supposed to be
a "half circle centered at the end point of the line" as documented
here: https://docs.blender.org/manual/en/dev/render/freestyle/
parameter_editor/line_style/strokes.html#caps

They are a shashed half circle instead.

This patch makes this pure half circles [and also fixes the case where
thickness of beginning was used for both beginning and end of the
stroke]

Fix T89765: boolean modifier collection refcount issue

The 'collection' property is flagged PROP_ID_REFCOUNT, so the
modifiers foreachIDLink functions should walk with IDWALK_CB_USER
(instead of IDWALK_CB_NOP).

Otherwise the modifier wont be included as a user for the collection
(e.g. on file read); removing the collection from the modifier will
decrement usercount though (which in worst case scenario makes the
collection orphan and will result in data loss)

Fix channel packed images display in the Image/Node editor

Channel packed images should not have their RGB affected by alpha.
rendering in Cycles and Eevee was fine already, but displaying these was
not right in the Image and Node editors.

Not 100% sure what to do for the "Color and Alpha" mode, but I guess
this should stay like it was before (applying the alpha).

"Color", "R", "G", and "B" modes were changed to not have color be
affected by alpha though.

Alembic export: evaluation mode option

This option will determine visibility on either render or the viewport
visibility. Same for modifer settings. So it will either evaluate the
depsgrah with DAG_EVAL_RENDER or DAG_EVAL_VIEWPORT.
This not only makes it more flexible, it is also a lot
clearer which visibility / modfier setting is taken into account (up
until now, this was always considered to be DAG_EVAL_RENDER)

This option was always present in the USD exporter, this just brings
Alembic in line with that.

Alembic: remove non-functional "Renderable Objects" only option

When introduced in {rB61050f75b13e} this was actually working (meaning
it checked the Outliner OB_RESTRICT_RENDER flag and skipped the object if
desired).

Behavior has since then been commented in rBae6e9401abb7 and apparently
refactored out in rB2917df21adc8.

If checked, it seemed to be working (objects marked non-renderable in
the Outliner were pruned from the export), however unchecking that
option did not include them in the export.

Now it changed - for the worse if you like - in rBa95f86359673 which
made it so if "Renderable Objects" only is checked, it will still export
objects invisible in renders. So since we now have the non-functional
option with a broken/misleading default, it is better to just remove it
entirely.

In fact it has been superseeded by the "Visible Objects" option (this
does the same thing: depsgraph is evaluated in render mode) and as a
second step (and to make this even clearer) a choice whether
Render or Viewport evaluation is used can be added (just like the USD
exporter has). When that choice is explicit, it's also clear which
visibility actually matters.

This is breaking API usage, should be in release notes.

Fix: VSE seeking with proxy strips would fail on certain frames

If the last decoded frame had the same timestamp as the GOP current
packet, then we would skip over this frame when fast forwarding and we
would seek until the end of the file.

This would could only be triggered reliably in single threaded mode.
