The crash was caused by a mistake in 5f9677fe0c
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.
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.

The Exact modifier code had been written to avoid using BMesh but
in the initial release the modifier still converted all Meshes to
BMeshes, and then after running the boolean code on the BMeshes,
converted the result back to a Mesh.
This change skips that. Most of the work here is in getting the
Custom Data layers right. The approach taken is to merge default
layers from all operand meshes into the final result, and then
use the original verts, edges, polys, and loops to copy or interpolate
the appropriate custom data layers from all operands into the result.
Having a vertex group in a mesh slowed down unrelated operations
such as selection.
De-duplicating custom-data arrays for layers that contain pointers
can become slow without any benefit as the content never matches.
Use full copies when storing custom-data for edit-mesh undo.
This improves the fix introduced in rBdc8b31af578bfcf9f77dbce6d7b7da1006a3c8c1.
While it did not result in other bugs afaik, I thought it would be
good to make the fix more specific, in case some other code did
expect `layer->data` to be null. This updated fix checks for the
very specific case the fix was intended for.
The issue was that boolean custom data layers were not written to files,
because the dna struct name `bool` does not exist. Adding a struct that
just contains a `bool/uint8_t` does not seem to be possible, it looks like
the minimum dna struct size is 4 bytes.
The proposed solution has two parts:
1. Write the custom data layer using `BLO_write_raw` instead of
`BLO_write_struct_array_by_name`.
2. When loading a file, reinitialize any custom data layer that was
not saved correctly (this is just a fix for existing files).

This adds a boolean attribute and custom data type, to be used in the
point separate node. It also adds it as supported data types in the
random attribute and attribute fill nodes.
There are more clever ways of storing a boolean attribute that make
more sense in certain situations-- sets, bitfields, and others, this
commit keeps it simple, saving those changes for when there is a proper
use case for them. In any case, we will still probably always want the
idea of a boolean attribute.

The alpha of the first layer was always used
here since introduction in rBee4453f08369 and was not updated when
customdata support for alpha was added.
Now also use the interpolated alpha.
thx @brecht noticing!

- Move some security checks outside of `interp` callbacks.
Namely, that we do get interpolation weights, and have something to
interpolate.
Some callbacks where not checking on those anyway, safer to move that
up into calling code.
- Cleanup usage of sub-weights, lots of interpolation callbacks wher
actually using those completely wrong.
- Change default behavior when no weights are given to higher-level API
functions: prevriously, each callback was responsible to handle that
case (and one did not even do it!), they were switching to purely
additive behavior then.
Instead, we now default to expected simple average of source values.
Note that the only real important change here is defaulting to actual
average of source value when no inertpolation weights are given (afaik,
this only happens in Weld modifier code).

This removes the limitation of the sculpt overlays not being visible

This puts all generic float/int/vector/color/string geometry attributes in a new
.attributes property. For meshes it provides a more general API for existing
attributes, for point clouds attributes will be used as an essential part of
particle nodes.
This patch was implemented by @lichtwerk, with further changes by me. It's
still a work in progress, but posting here to show what is going on and for
early feedback.

`CD_LOCATION` was only used temporarily due to the lack
of a better alternative. This also removes the name from
`CD_LOCATION` again, because at most one layer of this
type should exist.
Use binary search for querying deform weights.

Every Particle Simulation node has a name (or a path when it is in a node group).
This name has to be used in the Simulation modifier on a point cloud to see
the particles.
Caching has been disabled for now, because it was holding back development
a bit. To reset the simulation, go back to frame 1.
Currently, there is no way to influence the simulation. There are just some
randomly moving points. Changing that is the next step.
