This commit makes links connected to multi-input sockets spread verticaly
along the socket. Sockets grow if more links are connected and the node
layout updates accordingly. Links are sorted by their incoming angle
to avoid crossing links. Also, link picking is updated to work with
spread links and bezier links.
Currently the multi-input sockets are used in the join geometry node.
The mutli-input sockets look like a vertical rounded rectangle.
Currently they do not support the other custom socket shapes.

Passing 4x arguments for the rectangle,
mixed in with round-box radius & color wasn't very readable.
Instead, pass a `rctf` as the first argument to UI box drawing functions.
This commit moves runtime-only variables from the `SpaceNode`
DNA struct to a private struct in `node_intern.h`. Before, it was hard
to tell which data needed to be saved in files, this should make it
more clear.
Node that the `edittree` field is basically a runtime variable, since
it's set from the `treepath` list on read, but moving it would require
some more invasive changes that I don't think are worth it right now.
Also, not all of the moved variables were explicitly cleared on read--
`aspect` is set at the start of a redraw, `cursor` is set in a region
callback, and `recalc` was used as an update flag.

During the development of the new nodes in the `geometry-nodes` branch
the color of the new nodes wasn't considered, so all of the nodes ended
up red, the color for "input" nodes. This patch introduces two new
colors, one for "Geometry" and one for "Attributes". There are only two
attribute nodes currently, but the next sprint will add two more,
attribute mix, and sample from texture. The attribute nodes are
conceptually different enough from the nodes that modify the geometry
that they deserve their own color.

This is the initial merge from the geometry-nodes branch.
Nodes:
* Attribute Math
* Boolean
* Edge Split
* Float Compare
* Object Info
* Point Distribute
* Point Instance
* Random Attribute
* Random Float
* Subdivision Surface
* Transform
* Triangulate
It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier.
Notes on the Generic attribute access API
The API adds an indirection for attribute access. That has the following benefits:
* Most code does not have to care about how an attribute is stored internally.
This is mainly necessary, because we have to deal with "legacy" attributes
such as vertex weights and attributes that are embedded into other structs
such as vertex positions.
* When reading from an attribute, we generally don't care what domain the
attribute is stored on. So we want to abstract away the interpolation that
that adapts attributes from one domain to another domain (this is not
actually implemented yet).
Other possible improvements for later iterations include:
* Actually implement interpolation between domains.
* Don't use inheritance for the different attribute types. A single class for read
access and one for write access might be enough, because we know all the ways
in which attributes are stored internally. We don't want more different internal
structures in the future. On the contrary, ideally we can consolidate the different
storage formats in the future to reduce the need for this indirection.
* Remove the need for heap allocations when creating attribute accessors.
It includes commits from:
* Dalai Felinto
* Hans Goudey
* Jacques Lucke
* Léo Depoix
Don't refresh the list of sockets, so that when the .blend file is restored the
links remain valid. Also display such nodes in red to indicate an error, same
as when the node type info is missing.
This commit makes grid theming more consistent and capable by adding
some new theme colors related to grid rendering.
- Add grid theme color for node editor. `UI_view2d_multi_grid_draw`
is called with TH_GRID instead of a shaded `TH_BACK`.
Also color-blend `TH_NODE_GROUP`.
- Make the movie clip editor's clip preview grid respect grid theme
color (`ED_region_grid_draw` uses color-blended `TH_GRID`).
- Add versioning code to allow fixing existing themes (the resulting
themes should visually look the same as before)
These changes did cause some inconsistencies in the movie clip editor,
even after adjusting the themes accordingly:
1. The alpha slider of the grid color affects the background and not
the grid lines themselves.
2. The grids used by graph and dopesheet mode could already be themed
in the past. Now that the clip preview's grid can also be themed,
two different modes share the same theme color.

This replace `GPU_clear()` by `GPU_clear_color()` and `GPU_clear_depth()`.
Since we always set the clear value before clearing, it is unecessary
to track the clear color state.
Moreover, it makes it clearer what we clear the framebuffer to.
Issue introduced on fe045b2b77.
Since the stereoscopy compositing (anaglyph, ...) is only done for
viewports the VSE preview and compositor need to use viewports.

This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/editors/space_node` module.
No functional changes.
View2DScrollers used the memory manager to allocate memory. This isn't a
problem but in a upcoming change the scrollers will be drawn more often
than it used to (See {D8066}). To limit the number of allocations and
frees this patch will use the stack for allocation.

For buttons representing node inputs (e.g. in the material properties)
rather than drawing some generic socket icon, the actual sockets are
drawn now. That includes color, shape and the selection outline.
This should make it easier to understand what these buttons relate to.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
There was a mix of old and new constants. Now have one list of WM_CURSOR_*
cursor types, using GHOST standard cursors when available and otherwise falling
back to our custom cursors.
