Nodes: efficient node tree queries and inlining This adds two data structures that wrap a node tree. However, they work on different abstraction levels. `NodeTreeRef` is an immutable structure that makes working with a node tree in C++ much more efficient and convenient. It supports various queries efficiently, that are not easily possible using just `bNodeTree`. `DerivedNodeTree` builds on top of `NodeTreeRef`. It contains a flattened view on the node tree, i.e. with node groups being inlined. Every inlined node still knows its "call stack". It supports pretty much the same queries as `NodeTreeRef`. Both data structures come with a dot graph exporter for debugging purposes. Reviewers: brecht Differential Revision: https://developer.blender.org/D7628

Nodes: move some code from blenkernel directory to nodes This also introduces the `blender::nodes` namespace. Eventually, we want to move most/all of the node implementation files into this namespace. The reason for this file-move is that the code fits much better into the `nodes` directory than in the `blenkernel` directory.

* NodeTreeRef makes querying information about a bNodeTree more efficient. It is an immutable data
* structure. It should not be used after anymore, after the underlying node tree changed.
*
* The following queries are supported efficiently:
* - socket -> index of socket
* - socket -> directly linked sockets
* - socket -> linked sockets when skipping reroutes
* - socket -> node
* - socket/node -> rna pointer
* - node -> inputs/outputs
* - node -> tree
* - tree -> all nodes
* - tree -> all (input/output) sockets
* - idname -> nodes
*
* Every socket has an id. The id-space is shared between input and output sockets.
* When storing data per socket, it is often better to use the id as index into an array, instead
* of a hash table.
*
* Every node has an id as well. The same rule regarding hash tables applies.
*
* There is an utility to export this data structure as graph in dot format.

I do hope that I broke no builds, but it is quite likely that some compiler reports slightly different errors. Please let me know when there are any errors. If the fix is small, feel free to commit it yourself. I compiled successfully on linux with gcc and on windows.

Geometry Nodes: initial scattering and geometry nodes 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

Nodes: efficient node tree queries and inlining This adds two data structures that wrap a node tree. However, they work on different abstraction levels. `NodeTreeRef` is an immutable structure that makes working with a node tree in C++ much more efficient and convenient. It supports various queries efficiently, that are not easily possible using just `bNodeTree`. `DerivedNodeTree` builds on top of `NodeTreeRef`. It contains a flattened view on the node tree, i.e. with node groups being inlined. Every inlined node still knows its "call stack". It supports pretty much the same queries as `NodeTreeRef`. Both data structures come with a dot graph exporter for debugging purposes. Reviewers: brecht Differential Revision: https://developer.blender.org/D7628

Refactor: Update integer type usage This updates the usage of integer types in code I wrote according to our new style guides. Major changes: * Use signed instead of unsigned integers in many places. * C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`). * Hash values for C++ containers are 64 bit wide now (instead of 32 bit). I do hope that I broke no builds, but it is quite likely that some compiler reports slightly different errors. Please let me know when there are any errors. If the fix is small, feel free to commit it yourself. I compiled successfully on linux with gcc and on windows.

Geometry Nodes: initial scattering and geometry nodes 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

Nodes: efficient node tree queries and inlining This adds two data structures that wrap a node tree. However, they work on different abstraction levels. `NodeTreeRef` is an immutable structure that makes working with a node tree in C++ much more efficient and convenient. It supports various queries efficiently, that are not easily possible using just `bNodeTree`. `DerivedNodeTree` builds on top of `NodeTreeRef`. It contains a flattened view on the node tree, i.e. with node groups being inlined. Every inlined node still knows its "call stack". It supports pretty much the same queries as `NodeTreeRef`. Both data structures come with a dot graph exporter for debugging purposes. Reviewers: brecht Differential Revision: https://developer.blender.org/D7628

Refactor: Update integer type usage This updates the usage of integer types in code I wrote according to our new style guides. Major changes: * Use signed instead of unsigned integers in many places. * C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`). * Hash values for C++ containers are 64 bit wide now (instead of 32 bit). I do hope that I broke no builds, but it is quite likely that some compiler reports slightly different errors. Please let me know when there are any errors. If the fix is small, feel free to commit it yourself. I compiled successfully on linux with gcc and on windows.

Nodes: move some code from blenkernel directory to nodes This also introduces the `blender::nodes` namespace.
