temp-sculpt-colors: fix buf in next_color_attr

Sculpt-dev: fix bug in last commit

Sculpt-dev: cross-module ref cleanup

* Removed a bunch of nasty editors->blenkernel
dependencies (2 still remain).
* Fixed a few bugs in last commit.

WIP: Parial update skeleton.

WIP: partial update image.

Adding a basic mechanism that should be able to register tiles and find
changes. Not possible yet to loop over the updated tiles.
Next task would be to include reference to imbuf to get the width/height
of the images.

Added mark region dirty.

More tests and cleanups.

WIP: partial update image.

Differential Revision: https://developer.blender.org/D13238

Replaced internal gputexture generation with new partial update.

Removed unused code.

Multiple renames.

Cleanup: remove dummy multi function

Cleanup: Painting - reduce reallocation of same memory.

Curve mask is freed/allocated every time, but could still reuse the
previous allocated buffer when the diameter of the brush doesn't change.

Sculpt-dev: sculpt colors stuff

* Mask by color now works for dyntopo.
* Attribute and vertex color lists in the UI
now hide temporary CD layers.
* Added a specific op for removing vertex color
attributes.
* Fixed various bugs.

Cleanup: use same function for updating internal links for all nodes

Previously, node types had a callback that creates internal links. Pretty
much all nodes used the same callback though. The exceptions are the
reroute node (which probably shouldn't be mutable anyway) and some
input/output nodes that are not mutable.

Removing the callback helps with D13246, because it makes it easier
to reason about which internal links are created and when they change.
In the future, the internal links should be part of the node declaration.

temp-sculpt-colors: fix icons and a couple of bugs

Cleanup: Remove unused show_samples() device code in Cycles.

Cleanup: change node socket availability in a single place

This cleans up part of the code that still set the flag manually. Also, this
change helps with D13246 because it makes it easier to tag the node
tree as changed when the availability of a socket changed.

temp-sculpt-colors: Vertex color list now has active reference

LineArt: Ortho tolerance switch
