This adds the operator `OBJECT_OT_grease_pencil_add` to create a new grease pencil object.
Currently it supports the `EMPTY` and `STROKE` type.
This also replaces the add menu for the legacy grease pencil type in the Shift+A menu when the experimental option is enabled.

IndexMask::complement() is often used in geometry processing
algorithms when a selection needs to be inverted, mostly just in
curves code so far.
Instead of reusing `from_predicate` and lookup in the source mask,
scan the mask once, inserting segments between the original indices.
Theoretically this improves the performance from O(N*log(N)) to O(N).
But with the small constant offset of the former, the improvement is
generally just 3-4 times faster. However in some cases like empty
and full masks, the new code takes constant time.

Since avuitl 57.30.100 the pkt_duration is deprecated, and
the duration is to be used instead.
The units seems to match, and also from the avcodec decoder.c
the `frame->pkt_duration = frame->duration;` so does not seem
we need to do any conversion.
The change in FFmpeg is from 2022, which is a bit recent, so
the access to the duration is hidden behind a compatibility
API.

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:

In case a part of an override hierarchy would still be linked data, and
there would be other liboverride hierarchies sharing usage of that same
linked data, trying to create a partial override of that linked data
into a hierarchy would create very unreliable results.
This commit now only process each ID at most once, to ensure that the
liboverride will only be put in one liboverride hierarchy.
This is only a partial fix, results now should at least always be
valid. However, due to inheritently broken Outliner code when it comes
to same data in more than one path of the tree, the place where
(hierarchy in which) the new liboverride will be created is currently
'random' and unpredictable from user perspective.
This commit contains some code to try to alliviate that (by enforcing
processing of the active elements first), but unfortunately this does
not work either.
- Do not remap local liboverrides from other hierarchies when a
liboverride hierarchy root is provided (such that in case a linked
data is overridden as part of one hierarchy, the new liboverride does
not get assigned to other liboverride hierarchies of the same reference
data).
- Do not attempt to instanstiate newly overridden collections or objects
when they are part of a hierarchy and not the root of that hierarchy
(as they can be sondiered as already handled through that hierarchy
processing). Avoids attempts to instantiate them when doing partial
liboverride into an already existing hierarchy.
Adds the "Corners of Edge" topology node to geometry nodes.
Combining this node with the "Face of Corner" node allows getting
informations about the faces connected to an edge. The behavior is
slightly non-obvious-- the node only gives the corner neighbors
that come *before* the current edge in directly neighboring faces.
This allows the operation to be easily reversed and reduces
redundancy between nodes.

2ffd08e952 introduced new system to control attribute life time.
Some specific function for that system is missed in `Shortest Edge Paths`.
This pull request add this functions:
1. `reference_pass_all` for socket declarations.
2. `for_each_field_input_recursive` for field input nodes.

When entering sculpt mode on an object without any color attributes and
starting to paint, the newly created color attribute was set active, but
not default (camera icon).
Now set it default as well.

Follow up to [0], some material data wasn't accounted for.
- The embedded node-tree's owner_id wasn't set.
- Animation data (both the material & it's embedded node-tree).
- Updating depsgraph relations is needed when animation data is freed
as part of paste too.
Also report when paste fails.

Commented [0] (2.5x refactor that disabled many free functions),
for some reason this call was never re-enabled.
Add back the free call along with other clipboard buffers.

Cherry picked [1] from main as other fixes material clipboard
are difficult to validate when memory is leaking.

Use a macro to make the ID-free switch more compact & use ID indices
for better readability. Also typedef the enum so missing types in the
switch will report compiler warnings.
When a file passed in from the command line failed to load,
blender would exit & save the quit.blend.
Resolve by adding a `do_user_exit_actions` to WM_exit_ex which is
false in backgrounds mode or when an error has occurred.

Back-ported [0] & [1] from main with fix [2] included.

The "no custom" normal used to be stored inside the custom normal space
struct, now it's stored separately. Before the normal was modified, but
not the one in the normal space struct. Fixed by storing the original
before modification in a temporary variable.
This function replaced the evaluated mesh with a new one with the given
custom data type mask. That doesn't work in general anymore for a few
reasons: the increased dependence on named attributes (a opposed to
custom data types), and the "all or nothing" approach to reevaluating
the depsgraph. Other objects might depend on the object's evaluated
geometry, so it shouldn't just be replaced. Pushed a bit further, this could
give nice simplifications to mesh modifier evaluation.
There are two breaking changes, `bmesh_from_object` and BVH tree
`FromObject` require the source object to have a proper evaluated
mesh now.
If this causes a regression, it's likely that the object is missing
an update tag when a mode is entered that requires extra evaluated data.
