No idea why node editor remap callback was only handling scene IDs (and
not any other ntree owner)...
Note that this should be a safe fix, but it unvails a nice can of worm,
at some point we should ba able to handle all of that through libquery
only, get rid of editor's remap callbacks, and probably sanitize usages
of ID pointers by some of them, like that nodetree editor.
Current situation remains a fairly fragile mess...
Use the automatic property split layout (hence, change to the new 40/60% split
ratio) and add decorator buttons for animatable properties.
This actually applies to all node input buttons in the properties, e.g. world shading,
light shading, texture nodes.
Doing this makes the layout more consistent with other layouts in the
properties. But the decorators are also a useful hint for users that these
options can be animated. Previously using decorators and the automatic split
layout wasn't possible, I've done a number of changes now to have it supported.
Before I moved the socket icons to the left side, the decorators also looked
weird (two circle icons next to each other).

This commit adds the initial set of particles nodes. These are fairly
low level and are expected to be put into groups that we ship with Blender.

These socket types will be necessary for particle nodes.

Those new socket types will be necessary for particle nodes.
The main difficulty with adding these socket types is that they
are the first that reference ID data in their `value`.
Therefore, user counting code had to be added in a couple new places.

This implements a new builtin node tree type called `SimulationNodeTree`.
It is not yet embedded in the `Simulation` data block.
The node tree will initially be used for the new particle nodes system.
When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new
`Simulation Editor` is shown in the editors menu (which is just a node editor).
This patch does not add entries to the Add Node menu, so it is empty.

This editor's code was a bit schizophrenic, some parts considering its
nodetree usages as real refcounted ones, others, as shallow 'user one'
ones...
Editors should not be real ID users anyway, unless there are *very* good
reasons for it, so swich it to fully 'shallow' usage now.
Node input buttons (e.g. in the material properties) used to draw their
icons on the right of the buttons. However since they represent inputs,
it makes more sense conceptually to have them on the left.
Further, we might want to add the usual decorator buttons (to control
keyframes or display other states) to the material properties as well.
Having two circle icons next to each other would be confusing.

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.

- Use unicode right pointing triangle instead of arrow.
Existing code for ungrouping did not correctly handle user counters:
- counter for the group was not decremented
- counters for containing nodes were not incremented
The latter resulted in losing some nodes after orphan cleaning or several save/reload cycles.
The bug did not have destructive consequences until recently,
because it was compensated by another bug (fixed in rBe993667a46c2).

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).
No functional changes.
Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
This has some advantages over operator search:
- Some operators need options set to be usefully accessed.
- Shows key bindings to access menus
(for actions that don't have key bindings themselves).
- Non operator actions such as check-boxes are also shown.
- Menu items can control execution context, using invoke or execute
where appropriate so we can control how the operator runs.
Part of the design task T74157.
This can be tested using the 'Experimental' preferences section
or selected in the key-map editor.
While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

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.
Currently the link limit of sockets is stored in bNodeSocket->limit.
This allows for a lot of flexibility, but is also very redundant.
In every case I've had to deal with so far, it would have "more correct"
to set the link limit per socket type and not per socket. I did not enforce
this constraint yet, because the link limit is exposed in the Python API,
which I did not want to break here.
In the future it might even make sense to only support only three kinds of link limits:
a) no links, b) at most one link, c) an arbitrary number links links. The other link
limits usually don't work well with tools (e.g. which link should be removed when a new
one is connected?) and is not used in practice. However, that is for another day.
Eventually, I would like to get rid of bNodeSocket->limit completely and replace it
either with fixed link limits or a callback in bNodeSocketType.
This patch consists of three parts:
**1. Support defining link limit in socket type**
This introduces a new `nodeSocketLinkLimit` function that serves as an indirection to
hide where the link limit of a socket is defined.
**2. Define link limits for builtin sockets on socket type**
Data sockets: one input, many outputs
Virtual sockets: one input, one output
Undefined sockets: many inputs, many outputs (to avoid that links are removed when the type of the socket is not known)
**3. Remove `bNodeSocketTemplate->limit`**
This wasn't used anymore after the second commit. Removing it simplifies socket definitions
in hundreds of places and removes a lot of redundancy.
