When the mesh is linked, the materials can not be available or be the same assigned to mesh. Now, if the mesh is linked, a simple two materials conversion is used.
To get the full list of materials, the mesh must not be linked.
Also checked some indexes to be sure never get a wrong value and that materials are not created again and again.
`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.
This issue was produced by a hack in the sculpt mode code from 2.80
when the sculpt API for connectivity info was not available.
The smooth brush was the only brush that needed connectivity info,
so there were 3 different smooth functions with the connectivity
queries implemented for dyntopo, meshes and grids. The mesh version
of smoothing was checking the number of connected faces to a vertex
to mask the mesh boundaries, which was not covering all cases and
was hardcoded in the smooth function itself.
This patch removes all those legacy functions and unifies all
smooth functions into a single one using the new API and the
automasking system. In order to achieve this, there were needed
some extra changes:
- The smooth brush now does not automasks the boundaries by default,
so its default preset needs to be updated to enable automasking
- The mesh boundary info is extracted once and cached in a
bitmap, similar to the disconnected elements IDs. This makes
boundary detection work as expected in all cases, solving a lot
of known issues with the smooth brush. In multires, this info is
extracted and cached only at the base mesh level, so it is much
more memory efficient than the previous automasking system.
- In order to keep the brushes responsive as they were before,
the automasking system can now skip creating the cache when it
is not needed for the requested options. This means that for
high poly meshes and simple automasking options the brushes
won't lag on start.

It was already possible to create Sound and Image strips that reference
non-existing files. Now it's also possible to create Movie strips
referencing missing files via the Python API call
`Sequences.new_movie()`. In this case, the duration of the strip will be
set to 1 frame.
Note that this commit does not change anything in the user interface.
The Python API of the `MovieStrip` class is extended with a function
`reload_if_needed()`. This function only performs disk I/O if the movie
strip cannot produce frames, that is either when its filepath points to
a non-existing file, or when the video sequence editor has not been
shown yet (for example because it is in an inactive workspace).
This allows for the following:
```
import bpy
scene = bpy.context.scene
vse = scene.sequence_editor_create()
filepath = bpy.path.abspath('//demo.mkv')
strip = vse.sequences.new_movie("movie", filepath,
channel=2,
frame_start=47,
file_must_exist=False)
strip.frame_final_end = 327
```
This will create a new movie strip, even when `demo.mkv` does not exist.
Once `demo.mkv` has appeared at the expected location, either
`strip.reload_if_needed()` or `strip.filepath = strip.filepath` will
load it.

The force node can now be used to control the behavior of particles.
Forces can access particles attributes. Currently, there are three attributes:
`Position` (vector), `Velocity` (vector) and `ID` (integer).
Supported nodes are: Math, Vector Math, Separate Vector, Combine Vector and Value.
Next, I'll have to split `simulation.cc` into multiple files and move
some stuff out of blenkernel into another folder.
Make sure that proxy and original images are scaled to same size before
applying offset or crop.
During testing, I discovered, that raw cache will lose information whether
this image was proxy or not. Because of this, proxy images will not create
this cache type. It would be fairly easy to implement this functionality for
cache, but I have decided to not do it now, because I did not want to pass yet
another mostly hard-coded bool flag to cache system. Since image is proxy, it
should be fast to read anyway.
In case of using offset property, code was modified to make sure we scale
image only once. I also tried to make code more readable and streamlined and
cleaned up surrounding functions a bit.

Note that this behavior is enforced on user level for now, but on code
side it is controlled with a flag, which should make it easy to refine
that behavior if needed.
Only exception is when we duplicate a linked ID directly (then we assume
user wants a local deep-copy of that linked data, and we always also
duplicate linked sub-data-blocks).
Note that this commit also slightly refactor the handling of actions of
animdata, by simplifying `BKE_animdata_copy_id_action()` and adding an
explicit new `BKE_animdata_duplicate_id_action()` to be used during ID
duplication (deep copy).
This also allows us to get rid of the special case for liboverrides.
As tools iterators skip not visible vertices, fully hidden nodes can
also be skipped and considered as masked.

This implements the SCULPT_vertex_is_boundary and SCULPT_vertex_has_unique_face_set functions for PBVH_GRIDS, which makes features such as automasking now work in multires. It also fixes some other face sets related features in multires, like face set boundary smoothing.
This uses the BKE_subdiv_ccg_coarse_mesh_adjacency_info_get function to get the vertex indicies in the base mesh from multires. This way the API functions can get topology or face set information directly from it. In the future, these vertex indices can be used to get any other information from the base mesh from multires, like seams, sharp edges, disconnected elements IDs...

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.
Duplication and deletion code of modifiers was totally wrong for
particle system, that special weird thing needs its own custom
management.
Note that for now I chose not to duplicate the particle settings ID when
duplicating the modifier...
This uses the new implicit conversions and constructors
that have been committed in the previous commit.
I tested these changes on Linux with gcc and on Windows.
This adds new callbacks to `bNodeSocketType` and `bNodeType`.
Those are used to generate a multi-function network from a node
tree. Later, this network is evaluated on e.g. particle data.
