This avoids the need for manual memory management/raw pointers,
improves const correctness, improves type safety, simplifies iteration,
and simplifies the process of registering a new asset shelf type.

- Use unique_ptr instead of raw pointers
- Use Vector instead of a linked list
- Use a destructor instead of a free function
- Remove the space type template-- it's much clearer to copy functional code

This adds a Python API for layout panels that have been introduced in #113584.
Two new methods on `UILayout` are added:
* `.panel(idname, text="...", default_closed=False) -> Optional[UILayout]`
* `.panel_prop(owner, prop_name, text="...") -> Optional[UILayout]`
Both create a panel and return `None` if the panel is collapsed. The difference lies
in how the open-close-state is stored. The first method internally manages the
open-close-state based on the provided identifier. The second one allows for
providing a boolean property that stores whether the panel is open. This is useful
when creating a dynamic of panels and when it is difficult to create a unique idname.
For the `.panel(...)` method, a new internal map on `Panel` is created which keeps
track of all the panel states based on the idname. Currently, there is no mechanism
for freeing any elements once they have been added to the map. This is unlikely to
cause a problem anytime soon, but we might need some kind of garbage collection
in the future.
```python
import bpy
from bpy.props import BoolProperty
class LayoutDemoPanel(bpy.types.Panel):
bl_label = "Layout Panel Demo"
bl_idname = "SCENE_PT_layout_panel"
bl_space_type = 'PROPERTIES'
bl_region_type = 'WINDOW'
bl_context = "scene"
def draw(self, context):
layout = self.layout
scene = context.scene
layout.label(text="Before")
if panel := layout.panel("my_panel_id", text="Hello World", default_closed=False):
panel.label(text="Success")
if panel := layout.panel_prop(scene, "show_demo_panel", text="My Panel"):
panel.prop(scene, "frame_start")
panel.prop(scene, "frame_end")
layout.label(text="After")
bpy.utils.register_class(LayoutDemoPanel)
bpy.types.Scene.show_demo_panel = BoolProperty(default=False)

Extract:
- Sculpt filter types from the Sculpt menu. Some of these types use a
custom label, different from those defined in the operator RNA,
which was never extracted.
- "Today" and "Yesterday" from the file browser modification date.
- All name_plural from IDs, as these are used in the UI to list which
data block is to be removed, when calling outliner.orphans_purge.
Disambiguate:
- "Area", meaning the measurement of a surface as opposed to a place.

The previous limit of 63 bytes for the panel name was an issue for
languages where characters use multiple bytes. The UI would show panel
names truncated that had reasonably long/short names.
It's easy to support dynamically sized strings here, so do that instead
of using fixed size buffers.
Fixes#111927.

Previously, BKE level preview image code was in `BKE_icons.h` and `icons.hh`.
While these types are related, I always found this quite hard to navigate since
preview image stuff was just in the middle of icon functions. Plus, people
don't expect preview image functions in icon files, the relationship is not
obvious.
Instead, use focused files that make it easy to quickly navigate them
and see what they are dealing with.

4.0 files now include asset shelf regions in 3D views. This region type is not
known to older Blender versions. So far, in such cases we would just change
the region type to be the first known region type and keep the region storage
otherwise. This was arbitrary, and in fact unsafe: the reused settings may
violate invariants/assumptions for a region type and worse, the
`ARegion.regiondata` can only be interpreted and correctly written to files
if the region type is known.
Make sure all invalid regions (regions where the type cannot be restored) are
removed on file read.

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.
The `expand` callback is 'trivial' to replace, since it is only iterating
over ID pointers and calling a callback.
The only change in behavior here is that some pointers that were not
processed previously will now be.
In practice this is not expected to have any real effect (usually
the IDs used by these pointers would have been expanded through other
usages anyway). But it may solve a few corner cases, undocumented issues
though.
Part of implementing #105134: Removal of readfile's lib_link & expand code.
This commit adds a new option flag to the lib_query foreach_id code,
which will make deprecated ID pointers to be processed as well.
NOTE: Currently there is no report to the callbakcs about the fact that
it is processing a deprecated ID. This can be easily added later if it
becomes necessary.

Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.

No user visible changes expected, except of new experimental feature

This introduces asset shelves as a new standard UI element for accessing
assets. Based on the current context (like the active mode and/or tool), they
can provide assets for specific workflows/tasks. As such they are more limited
in functionality than the asset browser, but a lot more efficient for certain
tasks.
The asset shelf is developed as part of the brush assets project (see #101895),
but is also meant to replace the current pose library UI.
Support for asset shelves can quite easily be added to different editor types,
the following commit will add support for the 3D View. If an editor type
supports asset shelves, add-ons can chose to register an asset shelf type for
an editor with just a few lines of Python.
It should be possible to entirely remove `UILayout.asset_view_template()` once
asset shelves are non-experimental.
Some changes are to be expected still, see #107881.

Even if a text datablock was "used" by in the Text Editor, it would be
lost after save/reload if no fake user is set.
This is not in line with other datablocks if they are used by an editor
(e.g. images, clips, masks etc.).
Now handle this with `IDWALK_CB_USER_ONE` (instead of `IDWALK_CB_NOP`)
in `id_refcount_recompute_callback` >
`BKE_screen_foreach_id_screen_area` which re-ensures a user is set.
(Bit on shaky ground here, but this seems like this is how this is
handled for other editors "consuming" a datablock).

This change replaces a bare RenderEngine owned by a viewport
with a VeiwRender. This unlocks a possibility of accessing
RenderResult for viewport renders. Currently it is not done,
but it will be needed for an upcoming work towards unification
of the render passes handling.

Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.
