Adds the initial stage for the grease pencil 3.0 project.
This patch includes:
* New ID and new object type.
* New DNA structures.
* New drawing engine for grease pencil (gpencil-next).
* Tests for the new grease pencil data-type.
* A few operators for conversion, switching modes and (simple) drawing.
Exposed to the user:
* An experimental option to switch to the new grease pencil.
* This will switch the grease pencil render engine to gpencil-next which can only render the new object type.
Current grease pencil objects will no longer render.
* Changing this option currently requires a restart of blender (for the keymap to update).
* A conversion setting in the `Object` > `Convert To` operator.
* A drawing operator in `Draw Mode`.

The library is used by OBJ/PLY exporters, and asset_catalog_tree_view.
Performance of OBJ/PLY export seems to be the same. Blender executable
gets a tiny bit smaller (-5kb) on windows.
Avoid BLI_path_slash_rfind for accessing file-names as NULL is returned
when the path has no slashes, use BLI_path_basename instead.
Also remove 2 cases where BLI_path_basename was inlined.
The strlen() was passed in as a size argument, in this case it
couldn't have caused an overflow because the source & destination
happened to be the same size.
Also reduce the destination buffer size as this is used for an ID name.
- Don't use the source string length +1 as the size of the destination
(USD export & IMB_exr_get_handle_name).
- Correct undersized buffer being passed into imb_exr_insert_view_name.
- Don't use the source string length +1 as the size of the destination
(USD export & IMB_exr_get_handle_name).
- Correct undersized buffer being passed into imb_exr_insert_view_name.
In Blender the first and last points of a catmullRom curve are
treated as endpoints. To account for this in USD, we must set
the wrap attribute to 'pinned'. This lets the client know that
the first and last points are to be treated as points on the
curve, and that it needs to generate "phantom" points to account
for the start and end control points of a general catmullRom curve.

The goal is to make it more explicit and centralized operation to
assign and steal buffer data, with proper ownership tracking.
The buffers and ownership flags are wrapped into their dedicated
structures now.
There should be no functional changes currently, it is a preparation
for allowing implicit sharing of the ImBuf buffers. Additionally, in
the future it is possible to more buffer-specific information (such
as color space) next to the buffer data itself. It is also possible
to clean up the allocation flags (IB_rect, ...) to give them more
clear naming and not have stored in the ImBuf->flags as they are only
needed for allocation.
The most dangerous part of this change is the change of byte buffer
data from `int*` to `uint8_t*`. In a lot of cases the byte buffer was
cast to `uchar*`, so those casts are now gone. But some code is
operating on `int*` so now there are casts in there. In practice this
should be fine, since we only support 64bit platforms, so allocations
are aligned. The real things to watch out for here is the fact that
allocation and offsetting from the byte buffer now need an explicit 4
channel multiplier.
Once everything is C++ it will be possible to simplify public
functions even further.

This pull request addresses bug https://projects.blender.org/blender/blender/issues/107633
Added logic to avoid creating duplicate Blender shader nodes when
converting USD Preview Surface shaders that are connected to more
than one input.
This change adds a `NodePlacementContext::node_cache` map to record
Blender nodes converted for given USD shaders. The node creation
logic has been updated to query this cache to check if a node was
previously created for a given USD shader, before creating a
new node.

Using the topology map gives a constant time lookup, since it has a map
of nodes per type. The collada code used the old function, but had been
ifdef'd for four years, so it's removed here.
Include the term "overwrite" so users of this function are aware
this function will delete the destination file (unlike LIBC rename).
- Add BLI_rename_overwrite (previously called BLI_rename).
- BLI_rename is now a wrapper for rename.
Use BLI_rename when renaming in the file selector.
This pull request adds a 'root_prim_path' USD export string parameter. If this option is set to a well-formed prim path (e.g., '/World'), a transform primitive with the given path will be added to the stage as the parent of all exported primitives. This will allow transforming the scene by this root node in other applications and is also required for loading the exported scene as a reference in other USDs.
As part of this change, the '_materials' node, which contains all exported materials, is also created under the root prim. This is required so that materials are imported correctly when the USD is referenced in another stage.
Finally, added an export_params_valid() function to verify that the 'root_prim_path' is valid before starting the export job. This function can be extended in the future to perform additional validation of other export parameters.
This update combines work in pull request
https://projects.blender.org/blender/blender/pulls/104506
and an implementation in the 'universal-scene-description' branch.

See: https://projects.blender.org/blender/blender/issues/103343
Changes:
1. Added `BKE_node.hh` file. New file includes old one.
2. Functions moved to new file. Redundant `(void)`, `struct` are removed.
3. All cpp includes replaced from `.h` on `.hh`.
4. Everything in `BKE_node.hh` is on `blender::bke` namespace.
5. All implementation functions moved in namespace.
6. Function names (`BKE_node_*`) changed to `blender::bke::node_*`.
7. `eNodeSizePreset` now is a class, with renamed items.

Due a limitation in the precission of the thickness
calculation, the result could be wrong.
As the code tried to use the real thickness, in some
cases this was wrong.

Previously accessing the extension needed to ensure an extension
on an empty path.
This conflicted with DEBUG_STRSIZE as it was assumed the input was
FILE_MAX, where as it was a small buffer with RNA, see: !107602.
Resolve by separating the function that ensures the extension
with the function that finds valid extensions for a format.
Also pass the size of the filepath to functions that ensure the
extension.
Fixed bug where texture alpha was incorrectly remapped to red when exporting material shaders.
Now connecting the UsdPreviewSurface 'opacity' input to the UsdUVTexture 'a' output if the Blender texture image node source socket identifier is 'Alpha'.
Changes include the following:
The InputSpec::source_name struct member was removed, as the connection source name is now determined at runtime based on the Blender node input socket identifier.
The traverse_channel() utility function now returns a bNodeLink*, so that the source socket identifier can be queried from the link.
In create_usd_preview_surface_materia(), the code for creating and connecting a UsdUVTexture shader was reorganized to group it within one conditional block, to make it easier to follow. Also replaced a call to a deprecated version of UsdShadeInput::ConnectToSource().

- Rename name/filename/path to filepath when it's used for full paths.
- Rename name/path to dirpath when it refers to a directory.
- Rename file to filepath or path (when it may be a file or dir).
- Rename ImBuf::name & anim::name to filepath.
Rename BLI_make_existing_file to BLI_file_ensure_parent_dir_exists.
The previous name read as if it would make (touch) the file,
where as it ensures the directory component of the path exists.
Move from BLI_path to BLI_fileops as path utilities should only
manipulate paths and not deal with file IO creation
(this has more in common with BLI_file_touch for e.g.).
