There were enough cases of callers ignoring a potential the error value,
using the column width for e.g. to calculate pixel sizes, or the size in
bytes to calculate buffer offsets.
Since text fields & labels can include characters that return an error
from BLI_str_utf8_as_unicode, add the suffix to make this explicit.
Since [0] modal transform in the 3D viewport caused key-maps to be
rebuilt by the event system. Creating a temporary copy for
ViewOpsData_Utility flagged the key-map as outdated.
This could crash (resolved by [1] - for the most-part), but would still
rebuild the whole key-map, adding unnecessary overhead.
This would also reset the KMI_EXPANDED flag, causing transform
to hide key-map items when using Blender with the key-map editor open.
Add a function to temporarily suppress key-map updates.
While not ideal, full support for temporary key-maps that behave
differently to user key-maps is a bigger project for something
that's only needed in one place.

Display the modal keymap in the status bar for modal operators that
are called within macros. Most notably, the keymap for the transform
operator is displayed when it's called as part of the duplicate,
extrude, or loopcut operators or when moving nodes.

The check for control characters didn't account for delete (127).
This wasn't noticeable in most cases as delete is mapped to delete text.
Pressing Shift-Delete would enter 127 control character in the
text-editor, 3D text & Python console. This happened X11 & Wayland,
I didn't check other platforms.

Remove the requirement of restarting Blender to refresh the
extended 3D view menus for node group changes. Also avoid
rebuilding the tree of relevant assets and catalogs on every
redraw, since parsing asset libraries, etc. could become more
expensive than we want. Those two goals combined mean we
have to be more rigorous in how we invalidate the cached
catalog tree.
The first main change required is to clear the tree as asset libraries
are being read, similar to other dynamic asset menus. This is done
with a 3D view header listener rather than a menu listener in this case.
However, that isn't enough, because there is an issue with the asset
system where the "all" library isn't updated when the current file library
changes. The solution is to explicitly rebuild the "all" library's catalogs
when other asset libraries are changed.
The other necessity for dynamic updates is clearing the catalog tree
to be rebuilt when the node group "asset traits" are changed. This is
done with a new notifier type (with the goal of being a bit selective
about when we re-read assets). This _also_ requires running the
"presave" callback that builds asset metadata when updating the
property. Otherwise saving the file and sending the notifier is
necessary, which is too confusing.

In this case it didn't cause any problems however macros with a
BEGIN/END must always run both, not optionally run based on knowledge
of the iterator implementation cleanup requirement.
Any action that triggered the key-map to be rebuilt causes the key-map
UI to display freed data.
Recently key-map refreshing happens during transform, while this should
be resolved - it's still good to avoid a crash in this situation as it's
possible scripts perform actions that tag the key-map to be rebuilt
which is out of our control.
C++ callers must ensure the arguments are valid,
reserve validity for the RNA API for raising errors.
This is already the case for most RNA API calls that wrap BKE API's.
Ghost uses vulkan in its public headers but none of the projects that
depend on ghost had the vulkan headers in its includes nor did
bf_intern_ghost expose this vulkan dependency itself publicly yet.
bf_windowmanager also did not express its dependency on
bf_intern_ghost yet used its headers.
this change fixes both issues.

The operator system assumes that the `ot->ui` callback means
there will always be a redo panel. This situation where there is a
callback but sometimes no inputs hasn't been encountered before.
Resolve that by changing `WM_operator_check_ui_empty` into
a `WM_operator_ui_poll` that handles this case properly, with
a new operator type callback called `ui_poll`.
See #101778, #111346

This callback is actually never excuted when e.g. defining operators
buttons through the layout API.
A design task has also been created to keep track of this issue: #112253
The basic idea is very simple. Whenever a supported menu is open, one can just
start typing and this opens a search that contains all the (nested) menu entries.
The main downside is that this collides with accelerator keys. Those are the
underlined characters in each menu. For now, we just enable this new searching
behavior in a few selected menus: Node Add Menu, View3D Add Menu and
Modifier Add Menu.
This new functionality can be enabled for a menu by setting
`bl_options = {'SEARCH_ON_KEY_PRESS'}` to true in the menu type.
The status bar shows `Type to search...` when a menu is opened that supports search.

There are a couple of functions that create rna pointers. For example
`RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those
take an output parameter `r_ptr` as last argument. This patch changes
it so that the functions actually return a` PointerRNA` instead of using
the output parameters.
This has a few benefits:
* Output parameters should only be used when there is an actual benefit.
Otherwise, one should default to returning the value.
* It's simpler to use the API in the large majority of cases (note that this
patch reduces the number of lines of code).
* It allows the `PointerRNA` to be const on the call-site, if that is desired.
No performance regression has been measured in production files.
If one of these functions happened to be called in a hot loop where
there is a regression, the solution should be to use an inline function
there which allows the compiler to optimize it even better.

Loading add-ons after key-maps resolves a problem where add-ons would
setup shortcuts before Blender had created the key-maps.
Making add-ons have to declare the key-maps using region & window types
matching Blender's internal values.

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.

- Use `this->` to access class methods.
- Follow style guide for class definition order.
- Avoid unnecessary namespace redefinition.
- Make data struct local to node interface file.
Generally the context store is owned by `uiBlock`. Other pointers
to the store (in `bContext` and other operator data) shouldn't change
it, so those variables are now const. One exception is the pointer in
`uiLayout`, but that has a clearly short lifetime, so that's okay.
Remove the need for `CTX_store_copy` and `CTX_store_free` by using
C++ copy constructors, unique pointers, and `std::optional`. A few types
are made non-trivial to support this.

Switch to new node group interfaces and deprecate old DNA and API.
This completes support for panels in node drawing and in node group
interface declarations in particular.
The new node group interface DNA and RNA code has been added in parts
1 and 2 (#110885, #110952) but has not be enabled yet. This commit
completes the integration by
* enabling the new RNA API
* using the new API in UI
* read/write new interfaces from blend files
* add versioning for backward compatibility
* add forward-compatible writing code to reconstruct old interfaces
All places accessing node group interface declarations should now be
using the new API. A runtime cache has been added that allows simple
linear access to socket inputs and outputs even when a panel hierarchy
is used.
Old DNA has been deprecated and should only be accessed for versioning
(inputs/outputs renamed to inputs_legacy/outputs_legacy to catch
errors). Versioning code ensures both backward and forward
compatibility of existing files.
The API for old interfaces is removed. The new API is very similar but
is defined on the `ntree.interface` instead of the `ntree` directly.
Breaking change notifications and detailed instructions for migrating
will be added.
A python test has been added for the node group API functions. This
includes new functionality such as creating panels and moving items
between different levels.
This patch does not yet contain panel representations in the modifier
UI. This has been tested in a separate branch and will be added with a
later PR (#108565).

The logic in wm_jobs_timer made it seem as if timers might be shared
between wmJob's however this is never the case.
Replace a loop on wmJob's with a lookup & NULL check.
When a timer needs to execute during the idle time (currently 5ms), use
microsecond precision to ensure the timer isn't delayed by the idle
time.
This improves the precision of animation playback on systems that
support it
(WIN32, see note below).
In my tests FPS playback varied:
- 59.94 FPS would jitter between 58.13 & 63.11 FPS. 23.98 FPS would
- jitter between 23.68 & 24.31 FPS.
Using higher precision timers mostly resolves this issue although there
is still some jitter although it's now limited to ~0.01 FPS.
These values were measured with the FPS-Samples set to 1 to show the
real times between frames (without the values being smoothed out).
This is a continuation of a fix for #111579 which avoided the worst of
the jittering issues at higher frame rates.
It appears WIN32 doesn't support sleeping shorter than 1 millisecond via
`std::this_thread::sleep_for`, making this change have no benefit on
WIN32, from tests it also doesn't have any down sides, so avoid platform
specific logic. The WIN32 limitation is noted in code-comments. If a
method of higher precision method is available this can be investigated.
Setting the FPS to 120 caused the FPS to flicker erratically between
130 & 140 FPS.
This also impacted lower frame-rates with 23.98 playing back at 24.03
FPS on my system, 30 FPS played back at 30.13 FPS.
This problem was hidden by the FPS display rounding to an integer.
Regression in 2.5x series (worked in 2.49).
Resolve by clamping the sleep time in the main event loop so the 5ms
sleep doesn't result in sleeping when timers are scheduled to run.
There is still some visible FPS jitter that can be solved by using a
higher resolution sleep interval but that's out of scope for this fix.
This was noted in code comments and checked in Python documentation
generation but not at build time.
Since these enums are identifiers that end up included in various places
enforce the `rna_enum_*_items` convention which was noted as
the convention but not followed strictly.
Partially reverts [0], avoids having to deal with multiple prefix types.

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.
Part of implementing #105134: Removal of readfile's lib_link & expand code.
When choosing the new 'overwrite' option when trying to save a blendfile
from a newer version of Blender, it would cause invalid (use-after-free)
memory access.
Issue caused by the main commit (a1d7ec7139) of the new blendfile
compatibility handling. No idea how it was not detected earlier.
Many thanks to @weizhen for spotting the issue and doing some initial
investigation on it.
