Copying an existing scene was creating a new scene where all the
caches were off. Likewise, "show missing media" flag and proxy
settings was not copied either.

Original code was quite unorganized and not as easy to read through.
There were basically 3 code paths:
1. Division of `AVStream` duration by its timebase
2. Division of `AVFormatContext` duration by its timebase, with possible
AV offset compensation
3. Simply using frame count from `AVStream`
Finally there was possibility of ending up with duration of 0 in
specific case where `pFormatCtx->duration == AV_NOPTS_VALUE`, but I did
not find any test case for this (Added in aebb32748e).
During investigation for PR #126866, I have concluded, that before
commit 8903205dd9, the code which compared duration of stream and
container was incorrectly always true. But it resulted in correct
behavior for about 4 years. Code was reorganized with that assumption,
so above listed code paths are in order of possible execution. Exception
is code path 3, which is run first, but it's result is pretty much always
discarded.
Since all these workarounds are added around code path 3, it is safe
to assume, that it is least precise, so it should be considered last.

The change was accidentally done in #121383 which primarily concerned
itself with overlay text colors, but started to use TH_BACK theme color
for the draw manager text (e.g. for geometry nodes value visualization)
outline color. Change behavior to use black or white outline color, based
on lightness of text color.

In some cases when there are no faces there are no corner domain
topology attributes. Though this could be changed theoretically,
it's simpler to just make sure they exist in the few places we resize
a mesh rather than creating a new one from scratch.
It's possible for the `bArmature.collection_array` to be null if Bone
Collections were never added after armature creation. This could trip up
undo processing later when we call `MEM_freeN` on the collection.
Use a `MEM_SAFE_FREE` call instead which handles checking for null, as
well as setting to null when complete.

Make sure the deform normals caches stored in `SculptSession` are
cleared after topology changes. These should eventually be stored
in an actual mesh rather than `SculptSession` which would simplify
the situation.
Before some recent refactors, normals were always calculated
when creating the sculpt BVH tree. Switching from dyntopo BMesh
back to base mesh sculpting, that didn't happen anymore.
Nowadays it makes more sense to update the normals as necessary
where they are used, so the intent of the code that uses normals
is clearer.

The issue was that we were misinterpreting the `ANIMFILTER_FCURVESONLY`
flag in the animation filtering code. We were taking it to mean that
literally only actual fcurve channels should be included, but in fact
it should include the channel groups for those fcurve channels as well.
The graph editor code (but not the dopesheet code) depended on this
interpretation to function correctly, and doesn't display the groups
at all without it.
This fixes the issue by not excluding channel groups even when that
flag is set. This also updates the documentation of that flag to
clarify its actual semantics.

This removes `AnonymousAttributeID` which was "attached" to every anonymous
attribute before. It adds more complexity than is justified for its
functionality.
It was originally introduced to keep the reference count of the anonymous
attribute so that it can be deleted automatically when the attribute is not
referenced anymore. For quite some time we have had deterministic attribute
life-times though which don't rely on the reference count anymore.
Anonymous attributes are sometimes shown in the UI as "friendly looking" string
like `"UV Map" from Cube`. Some information necessary for this was also stored
in `AnonymousAttributeID`. However, this can also be solved differently.
Specifically, this functionality has now been added directly to
`AttributeFieldInput`.
This refactor also allows removing `AttributeIDRef` which was mainly introduced
because we had to keep the `AnonymousAttributeID` attached with the attribute
name. Just using simple string types to identify attributes can reduce the
mental overhead quite significantly. This will be done as a separate refactor
though.

This change does some preparations before we implement persistent
caching for static shaders.
- Move ownership of pipeline cache to the pipeline pool.
- Use two pools. one is only used for static shaders
other for non static shaders.

The term "tool" is historic from before the actual tool system got
introduced. Since then the term was already a bit confusing, because it
wasn't directly related to the tool system, but there was still some
relationship between the two. Now brushes and their types are decoupled
much more from the tool system, with a single "Brush" tool supporting
all kinds of brushes (draw, grab, cloth, smooth, ...).
For a more clear terminology, use "brush type" instead of "tool".
For #126032 we need to write the brush type to the asset metadata (done
in !124618), so we can filter brushes based on the type (so the grease
pencil eraser tool only shows eraser brushes, for example). I'd like to
use future proof names for that to avoid versioning of asset metadata in
future, so I'd rather do the full naming change now.
RNA properties (thus BPY names) are not changed for compatibility
reasons. Can be done in 5.0, see blender/blender#124201.

Calling exit() runs temporary directory cleanup and other atexit

Remove call to BM_elem_attrs_copy in face interpolation function.
This was copying custom-data which cleared the faces CD_BM_ELEM_PYPTR,
making the Python objects behave as if it was removed.
While the issue could also be fixed by skipping the PYPTR layer,
copying attributes such as the material & normal in a face-data
interpolation function isn't correct. In cases where this is needed,
it's better the caller handles copying attributes.
Port the macOS version of the `BLI_delete_soft` function from raw
runtime `objc_*` calls function to proper Objective-C for increased
readability and long-term maintainability. This new function is placed
in a new `intern/fileops_apple.mm` file, analogous to the existing
`intern/storage_apple.mm` file.

`atan2(0, 0)` is undefined on many platforms. To ensure consistent
result across platforms, we return `0` in this case.
Note only the behavior of the shader node `Artan2` is changed here.
During shading, we might still produce `atan2(0, 0)` internally and
cause different results across platforms, but that usually happens with
single samples and is not obvious, plus checking this condition all the
time is costly. If later we find out it's indeed necessary to change all
the invocation of `atan2(0, 0)`, we could change the wrapper functions
in `metal/compat.h` and `mtl_shader_defines.msl`.

In this case, the `PoseBackup` created by
`action_preview_render_prepare` wasnt cleaned up properly (because
`action_preview_render` was earlied out).
So to resolve, call `action_preview_render_cleanup` as well when
earlying out)

VSE timeline, when many (hundreds/thousands) of thumbnails were visible, was
very slow to redraw. This PR makes them 3-10x faster to redraw, by stopping
doing things that are slow :) Part of #126087 thumbnail improvements task.
- No longer do mute semitransparency or corner rounding on the CPU, do it in
shader instead.
- Stop creating a separate GPU texture for each thumbnail, on every repaint,
and drawing each thumbnail as a separate draw call. Instead, put thumbnails
into a single texture atlas (using a simple shelf packing algorithm), and
draw them in batch, passing data via UBO. The atlas is still re-created every
frame, but that does not seem to be a performance issue. Thumbnails are
cropped horizontally based on how much of their parts are visible (e.g. a
narrow strip on screen), so realistically the atlas size is kinda
proportional to screen size, and ends up being just several megabytes of data
transfer between CPU -> GPU each frame.
On this Sprite Fright edit timeline view (612 visible thumbnails), time taken
to repaint the timeline window:
- Mac (M1 Max, Metal): 68.1ms -> 4.7ms
- Windows (Ryzen 5950X, RTX 3080Ti, OpenGL): 23.7ms -> 6.8ms
This also fixes a visual issue with thumbnails, where when strips are very
tall, the "rounded corners" that were poked right into the thumbnail bitmap
on the CPU were showing up due to actual bitmap being scaled up a lot.

This commit adds a python script that can collect some of the
information necessary to fill out a bug report.
The primary use case is to help users collect system information for
a bug report in the case that Blender can't open.
CMD and sh files are included to help users use the Python script.
Ref !122191
This commit mainly replaces a lot of `memset(0)` by empty value
initialization of `PointerRNA` and related data.
It also moves a few remaining areas from C alloc/free to C++ new/delete
memory hanlding.
Part of the effort to make PointerRNA non-trivial (#122431).
This issue only applied to layered actions.
The issue was that the `restore_channel_group_invariants()` method was
being called too early in the remove fcurve function, and thus fcurves'
group pointers could end up inconsistent with the membership specified
in the groups.
This commit fixes the issue by moving the call to
`restore_channel_group_invariants()` to the end of the function, where
it belongs.

Add two new operators, `anim.slot_new_for_id` and
`anim.slot_unassign_from_id`. These are used in the Action editor and
the Animation panels in the Properties editor, to respectively create a
new Action Slot for an ID and to unassign whatever slot is currently
assigned to that ID.
The latter operator also replaces the C++ operator
`anim.slot_unassign_object`, which was specifically made for the
Dopesheet header. The Python ones are generic enough to be used there
too.
