This allows using C++ types in the region runtime data, which will
make it easier to move the remaining runtime data out of the
`ARegion` DNA type and improve code readability in these areas.

Previously, it was not possible to see detailed information about instances in
the spreadsheet. Only the attributes on the top level instances were shown. Now,
all nested instances can be inspected too.
Combined with #114910 this will make inspecting more complex geometry with the
spreadsheet much more feasible. It's also an important part of integrating
grease pencil into geometry nodes because it makes it more obvious how layers
are converted to curve instances.
The data-selection is split into two separate tree views now. One that selects
the geometry from the instance tree, and one that's used to select the geometry
component and domain within that geometry. We found that this works better than
combining both tree views into one (we tried that in #124186).

This makes the read and write API functions match more closely, and adds
asserts to check that the data size is as expected.
There are still a few places remaining that use BLO_read_data_address
and similar generic functions, these should eventually be replaced as well.

Implements the design from #116067.
The socket type is called "Matrix" but it is often referred to as "Transform"
when that's what it is semantically. The attribute type is "4x4 Matrix" since
that's a lower level choice. Currently matrix sockets are always passed
around internally as `float4x4`, but that can be optimized in the future
when smaller types would give the same behavior.
A new "Matrix" utilities category has the following set of initial nodes"
- **Combine Transform**
- **Separate Transform**
- **Multiply Matrices**
- **Transform Direction**
- **Transform Vector**
- **Invert Matrix**
- **Transpose Matrix**
The nodes and socket type are behind an experimental flag for now,
which will give us time to make sure it's the right set of initial nodes.
The viewer node overlay doesn't support matrices-- they aren't supported
for rendering in general. They also aren't supported in the modifier interface
currently. But they are supported in the spreadsheet, where the value is
displayed in a tooltip.

The ID remapper code was already largely defined in a CPP struct
(IDRemapper). Make this an actual class, and remove the C API wrapper
around.
This makes the code cleaner, easier to follow, and easier to extend or

This implements the core changes for this design: https://devtalk.blender.org/t/grease-pencil-integration-into-geometry-nodes/31220
The changes include:
* Add `CustomData` for layer attributes
* Add attribute support for the `GreasePencilComponent` to read/write layer attributes. Also introduces a `Layer` domain.
* Implement a `GreasePencilLayerFieldContext` and make `GeometryFieldContext` work with grease pencil layers.
* Implement `Set Position` node for `Grease Pencil`.
Note: These changes are only accessible/visible with the `Grease Pencil 3.0` experimental flag enabled.

The hash tables and vector blenlib headers were pulling many more
headers than they actually need, including the C base math header,
our C string API header, and the StringRef header. All of this
potentially slows down compilation and polutes autocomplete
with unrelated information.
Also remove the `ListBase` constructor for `Vector`. It wasn't used
much, and making it easy to use `ListBase` isn't worth it for the
same reasons mentioned above.
It turns out a lot of files depended on indirect includes of
`BLI_string.h` and `BLI_listbase.h`, so those are fixed here.

The `lib_link` callback cannot always be fully replaced/removed, as in
some case it is also doing some validation checks, or data editing based
on the result of lib_linking internal ID pointers.
The callback has been renamed for that purpose, from `read_lib` to
`read_after_liblink`. It is now called after all ID pointers have been
fully lib-linked for the current ID, but still before the call to
`do_versions_after_linking`.
This change should not have any behavioral effect. Although in theory
the side-effect of this commit (to split lib linking itself, and the
validation/further processing code) into two completely separated steps
could have some effects, in practice none are expected, and tests did
not show any changes in behavior either..
Part of implementing #105134: Removal of readfile's lib_link & expand code.
Including <iostream> or similar headers is quite expensive, since it
also pulls in things like <locale> and so on. In many BLI headers,
iostreams are only used to implement some sort of "debug print",
or an operator<< for ostream.
Change some of the commonly used places to instead include <iosfwd>,
which is the standard way of forward-declaring iostreams related
classes, and move the actual debug-print / operator<< implementations
into .cc files.
This is not done for templated classes though (it would be possible
to provide explicit operator<< instantiations somewhere in the
source file, but that would lead to hard-to-figure-out linker error
whenever someone would add a different template type). There, where
possible, I changed from full <iostream> include to only the needed
<ostream> part.
For Span<T>, I just removed print_as_lines since it's not used by
anything. It could be moved into a .cc file using a similar approach
as above if needed.
Doing full blender build changes include counts this way:
- <iostream> 1986 -> 978
- <sstream> 2880 -> 925
It does not affect the total build time much though, mostly because
towards the end of it there's just several CPU cores finishing
compiling OpenVDB related source files.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
The issue was that `is_rendering` was used as a proxy to check
whether the interface is locked. Locking the node editor during rendering
is not necessary, but it currently is necessary while baking, because
baking changes original data from a different thread.
The solution is to use the already existing mechanism to tell Blender
which regions should be locked when the interface is locked.
The usage of the lib pointer was cryptic to say the least, it was
essentialy used to allow or not local IDs results in the mapping
old_id_pointer -> new_id_pointer lookup result.
Now:
- Explicitely pass a boolean to allow or not local ID as result in
lower-level code.
- Pass the 'self ID' pointer instead of its library to the whole
liblinking code (that was already the case in a few places).
Note that naming of the 'self id' pointer is currently very inconsistent
throughout the readfile liblink code, this will have to be cleaned up in
a separate step later. For now, `self_id` has been chosen for new code
as it matches the terminology in lib_query code.
The later change can also allow finer handling of lookup on undo, based
on how it was re-read (or not), should the need for this arise.
Fixes crashes in timeline and spreadsheet editors during simulation
nodes baking:
* Timeline tries to access the `states_at_frames_` list of the cache to
determine which frames to draw as baked. This can collide with the
baking thread. Needs a mutex to safely access the cache state.
Note: the old point cache has a pre-allocated flag array
`cached_frames` which the baking thread writes into while timeline is
reading it concurrently - not thread-safe but harmless.
* Spreadsheet keeps a data pointer during drawing, which may become
deallocated when the cache is updated. Common approach here is to use
`G.is_rendering` to lock the editor while baking.

Node socket tooltips suffered from several issues.
- Some could not be translated because they were not properly
extracted, so extraction macros were added.
- Some were extracted but included newlines at the end which did not
get translated, such as `ss << TIP_("Geometry:\n")`, changed to
`ss << TIP_("Geometry:") << "\n"`.
- Some translations were not functional, such as:
`TIP_(attributes_num == 1 ? " Named Attribute" : " Named Attributes");`
because `TIP_()` needs to be around a single string.
- Some extraction macros had no effect and were removed, such as:
`.description(N_(leading_out_description));`
This is a no-op macro which can be used only around a string literal.

This type will be used to store mesh edges in #106638, but it could
be used for anything else too. This commit adds support for:
- The new type in the Python API
- Editing the type in the edit mode "Attribute Set" operator
- Rendering the type in EEVEE and Cycles for all geometry types
- Geometry nodes attribute interpolation and mixing
- Viewing the type in the spreadsheet and using row filters
The attribute uses the `blender::int2` type in most code, and
the `vec2i` DNA type in C code when necessary. The enum names
are based on `INT32_2D` for consistency with `INT8` and `INT32`.

For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

This adds support for showing geometry passed to the Viewer in the 3d
viewport (instead of just in the spreadsheet). The "viewer geometry"
bypasses the group output. So it is not necessary to change the final
output of the node group to be able to see the intermediate geometry.
**Activation and deactivation of a viewer node**
* A viewer node is activated by clicking on it.
* Ctrl+shift+click on any node/socket connects it to the viewer and
makes it active.
* Ctrl+shift+click in empty space deactivates the active viewer.
* When the active viewer is not visible anymore (e.g. another object
is selected, or the current node group is exit), it is deactivated.
* Clicking on the icon in the header of the Viewer node toggles whether
its active or not.
**Pinning**
* The spreadsheet still allows pinning the active viewer as before.
When pinned, the spreadsheet still references the viewer node even
when it becomes inactive.
* The viewport does not support pinning at the moment. It always shows
the active viewer.
**Attribute**
* When a field is linked to the second input of the viewer node it is
displayed as an overlay in the viewport.
* When possible the correct domain for the attribute is determined
automatically. This does not work in all cases. It falls back to the
face corner domain on meshes and the point domain on curves. When
necessary, the domain can be picked manually.
* The spreadsheet now only shows the "Viewer" column for the domain
that is selected in the Viewer node.
* Instance attributes are visualized as a constant color per instance.
**Viewport Options**
* The attribute overlay opacity can be controlled with the "Viewer Node"
setting in the overlays popover.
* A viewport can be configured not to show intermediate viewer-geometry
by disabling the "Viewer Node" option in the "View" menu.
**Implementation Details**
* The "spreadsheet context path" was generalized to a "viewer path" that
is used in more places now.
* The viewer node itself determines the attribute domain, evaluates the
field and stores the result in a `.viewer` attribute.
* A new "viewer attribute' overlay displays the data from the `.viewer`
attribute.
* The ground truth for the active viewer node is stored in the workspace
now. Node editors, spreadsheets and viewports retrieve the active
viewer from there unless they are pinned.
* The depsgraph object iterator has a new "viewer path" setting. When set,
the viewed geometry of the corresponding object is part of the iterator
instead of the final evaluated geometry.
* To support the instance attribute overlay `DupliObject` was extended
to contain the information necessary for drawing the overlay.
* The ctrl+shift+click operator has been refactored so that it can make
existing links to viewers active again.
* The auto-domain-detection in the Viewer node works by checking the
"preferred domain" for every field input. If there is not exactly one
preferred domain, the fallback is used.
Known limitations:
* Loose edges of meshes don't have the attribute overlay. This could be
added separately if necessary.
* Some attributes are hard to visualize as a color directly. For example,
the values might have to be normalized or some should be drawn as arrays.
For now, we encourage users to build node groups that generate appropriate
viewer-geometry. We might include some of that functionality in future versions.
Support for displaying attribute values as text in the viewport is planned as well.
* There seems to be an issue with the attribute overlay for pointclouds on
nvidia gpus, to be investigated.
