EEVEE: Fix incorrect volumetric light shadowing

The shadowing was computed on the light distance squared,
leaking to much light since it was integrating the extinction behind
the ligth itself.

Also bump the maximum shadow max step to the actual UI values. Otherwise
we get shadowing under evaluated because `dd` is too small.

Fix (unreported) light cache bake crash

missing NULL check if there is no cache there to begin with.

Sculpt: Expand Operator

Expand is a new operator for Sculpt Mode which is intended to be the main
tool for masking, Face Set editing, interacting with the filters and pattern
creation.

The fundamentals of the tool are similar to the previous sculpt.mask_expand
operator. It shares the same default shortcuts and functionality, making
the previous operator obsolete.

The shortcuts to execute the operator are:
- Shift + A: Expand mask
- Shift + Alt + A: Expand mask by normals
- Shift + W: Expand Face Set
- Shift + Alt + W: Resize current Face Set

The main changes compared to the previous sculpt.mask_expand operator are:
- Modal keymap, all operator options can be changed in real time while the
operator is running.
- Supports creating Mask, Face Sets and Sculpt Vertex Colors.
- Much better code, new features can be easily integrated.

Limitations:
- All Mask operations are supported for Sculpt Vertex colors, but not exposed
by default as their support is still experimental.
- Dyntopo does not support any Face Set or Sculpt Vertex Colors. functionality
(they are not implemented in general for Dyntopo).
- Multires does not support any feature related to geodesic distances.
- Multires does not support vertex colors.
- Multires does not support recursions.
- In Multires, Face Sets snaping does not initialize all current enabled Face
Sets when toggling snapping.
- In Multires, Face Sets are created at base mesh level (works by this by
design, like any other tool).
- Unlike the previous mask_expand operator, this one does not blur the mask
by default after finishing Expand as that does not fit the new design.
The mask can still be blurred by using the mask filter manually.

Fix T86026: Crash Opening Cryptomatte File.

Not sure this fixes the root cause. It seems that memory corruption
happens in dynstr. This patch replaces dynstr with a streamstring.

Fix crash on NULL dereference

Fix T86138 EEVEE: Bake Indirect Lighting crash in 2.93 with older files

This was caused by a missing version check.

Fix T86172: check if attribute is actually accessible

The crash happened when the density in the Point Distribute node was
above zero but so small, that no point was generated. In this case, there
was a point cloud component, but the point cloud was empty, making some
attributes unavailable.

One could also make more attributes available in this case, but that can
be done separately if necessary.

EEVEE: Depth of field: Do not shrink highlights when using overblur

This fixes the issue of bokeh size being smaller when using overblur.

The additional overblur needs to be centered on the outer radius.

VSE: Refactor meta operators

Move low level logic to module code and versioning logic to versioning code.

Metas strip position was handled in diffrent way compared to other strips.
This was introduced in c8b0d25794be as bugfix for T28158.
I disagree with such design. Meta strips should be handled in same way as
any other strips.

I have tested this change and haven't found any problems.
No problems after checking T28158 as well.
There should be no functional changes on user level.

Fix T85981, part II: bone's custom shape disappear on undo in some cases.

Nicely hidden bug in pose read library code, it was using the library
from the wrong ID as reference to relink the custom shape object pointer
(pose is data from Object, not Armature).

Fix T85970: Incorrect scaling of meta strips

This is same issue as fixed by d85789255320, but I forgot to check meta

FFmpeg: Improve scrubbing performance

Applying negative offset to seek position before scanning doesnn't have
any effect. This change results in 1.5x faster seeking (random frame,
average value) in sample file with 30 frame GOP length.

If I am not mistaken, B frames can have pts that can be less than
pts of I frame that must be decoded. Even in this case though, B frame
packet will be stored after that I frame.

In addition, preseek value is de facto hardcoded so seeking would fail
if it could. This can be hard to spot though.

VSE: Refactor VSE strip loading code

Isolate RNA and operator logic from functions that create strips.
- Operator specific code was removed from `SeqLoadInfo` structure and
`SEQ_add_*` functions.
- Strip loading code was removed from RNA and operator functions.
- `SEQ_add_*` API was unified to work on `SeqLoadData` struct.
Only exception is image strip, which require files to be loaded
separately to strip creation itself. This is not ideal, but I think
it's acceptable.
- Some functions and variables were refactored so the code reads
better.

There are minor functional changes (coincidental bugfixes):
- Operator errors are reported per-strip. Previously they were not
reported at all?
- `new_sound()` RNA API function now create sound with length of 1
if source file does not exist. Previously it created strip with
length of 0.
- Replace selection operator property wasn't working correctly.
Fixed in this patch.

Geometry Nodes: show "Show Texture in texture tab" button

This enables the quick access button [to show the relevant Texture in
the Properties Editor] for textures used in geometry nodes.

This goes in line to what we do for other textures:
- modifier textures have this button
- particle textures have this button
- brush textures will soon have it, too (see D9813)

When outside of the Properties Editor, the button will always show (if a
texture is actually assigned), but will be inactive if no suiting
Properties Editor to show the texture in can be found.

Note this also changes the behavior to not show the button if _no_
texture is assigned (as in: we are still showing the "New" button).
Previously it was always there (e.g. for modifier textures), even if it
would take us to an empty texture tab. (Sure, we could add a texture
there then, but imho it makes more sense to just start showing it once a
texture is already there)

For this to work with geometry nodes, the following chages were done:
- implement foreachTexLink for geonode modifiers
- new buttons_texture_user_node_property_add() that stores prop as well
as node
- also use NODE_ACTIVE_TEXTURE flag in geometry nodetrees

notes:
- this still uses the first suiting (as in: pinning does not interfere)
Properties Editor it finds, this should (maybe?) find the _closest_
Property Editor instead (see related feedback in D9813).
- this will already show the button for brush textures as well
(disabled), but there is another mandatory change in an upcomming commit
to make it work there as well (see D9813)
