The `__enter__` function of the `bpy.data.libraries.load` context manager
was storing a pointer to a stack-allocated variable, which was subsequently
used in the `__exit__` function, causing a crash. This is now fixed.
Thanks @Severin for the patch.
This adds id_properties_clear() and id_properties_ensure() functions
to RNA structs. This is meant as an initial change based on discussion
in review of D9697. However, they may be useful in other situations.
The change requires refactoring the internal idproperties callback to
return a pointer to the IDProperty pointer, which actually turns out
to be quite a nice cleanup.
An id_properties attribute could be added in the future potentially.

This reverts commit rB3a48147b8ab92, and fixes the issues with linking
etc.
Change compared to previous buggy commit (rBf8d219dfd4c31) is that
new `BlendFileReadReports` reports are now passed to the lowest level
function generating the `FileData` (`filedata_new()`), which ensures
(and asserts) that all code using it does have a valid non-NULL pointer
to a `BlendFileReadReport` data.
Sorry for the noise, it's always when you think a change is trivial and
do not test it well enough that you end up doing those kind of
mistakes...
This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,
etc.

Allows to define properties which will have proper units displayed
in the interface. The internal storage is expected to be seconds
(which matches how other times are stored in Blender).
Is not immediately used in Blender, but is required for the upcoming
feature in Cycles X (D11526)
The naming does not sound very exciting, but can't think of anything
better either.
For test it probably easiest to define FloatProperty with subdtype
of TIME_ABSOLUTE.

No functional changes as logic elsewhere already ensured this.
This just makes it obvious to anyone reading over the code that
these arguments are keyword only.
Add a doc-string explaining the purpose of each call back and
how they should be used.
Also add a currently unused callback 'POST_FAIL' that is to be used in
cases the action fails - giving script authors, a guarantee that a
call to `pre` will always have a matching `post/post_fail` call.
- D11422: adds a callback that can use 'post_fail'.
- T88696: proposed these conventions.
Adds internal API for creating and managing OpenXR actions at the
GHOST and WM layers. Does not bring about any changes for users since
XR action functionality is not yet exposed in the Python API (will be
added in a subsequent patch).
OpenXR actions are a means to communicate with XR input devices and
can be used to retrieve button/pose states or apply haptic feedback.
Actions are bound to device inputs via a semantic path binding
(https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html#semantic-path-interaction-profiles),
which serves as an XR version of keymaps.
Main features:
- Abstraction of OpenXR action management functions to GHOST-XR,
WM-XR APIs.
- New "xr_session_start_pre" callback for creating actions at
appropriate point in the XR session.
- Creation of name-identifiable action sets/actions.
- Binding of actions to controller inputs.
- Acquisition of controller button states.
- Acquisition of controller poses.
- Application of controller haptic feedback.
- Carefully designed error handling and useful error reporting
(e.g. action set/action name included in error message).

- Matches changes in Python 3.x dictionary methods.
- Iterating now raises a run-time error if the property-group changes
size during iteration.
- IDPropertyGroup.iteritems() has been removed.
- IDPropertyGroup View & Iterator types have been added.
- Some set functionality from dict_keys/values/items aren't yet
supported (isdisjoint method and boolean set style operations).
Proposed as part of T85675.
Python scripts can now define the reason it's poll function fails using:
`Operator.poll_message_set(message, ...)`
This supports both regular text as well as delaying message creation
using a callback which should be used in situations where constructing
detailed messages is too much overhead for a poll function.

- Optionally get the error as a single line.
- Support access the error as an allocated string.
- PyC_ExceptionBuffer_Simple was always printing to the `stdout` while
PyC_ExceptionBuffer didn't, now either print to the output.
Without this, callers are unable to do anything with the error string.
When using `bpy.data.actions[action_name, "nonexistant-library"]`,
use the term `filepath` instead of `name` in the error message.
Also increase the size to match the file path length.

This patch adds support to export and import grease pencil in several formats.
Inlude:
* Export SVG
* Export PDF (always from camera view)
* Import SVG
The import and export only support solid colors and not gradients or textures.
Requires libharu and pugixml.
For importing SVG, the NanoSVG lib is used, but this does not require installation (just a .h file embedded in the project folder)
Example of PDF export: https://youtu.be/BMm0KeMJsI4

Callbacks used in `bpy.props` didn't hold a references to the functions
they used.
While this has been the case since early 2.5x it didn't cause any
problems as long as the class held a reference.
With Python 3.10 or when using `from __future__ import annotations`,
the annotations are no longer owned by the class once evaluated.
Resolve this by holding a reference in the module, which now supports
traverse & clear callbacks so the objects are visible to Python's
garbage collector.
Also refactor storage of Python data, moving from an array into a struct.
This adds support for creating a `BlendFile` (internally called `Main`),
which is limited to a context.
Temporary data can now be created which can then use
`.libraries.load()` the same as with `bpy.data`.
To prevent errors caused by mixing the temporary ID's with data in
`bpy.data` they are tagged as temporary so they can't be assigned
to properties, however they can be passed as arguments to functions.

The `MAX_LIBARRAY` define was an annoying doublon to the `INDEX_ID_MAX` enum value
now defined in `DNA_ID.h`, and it is no more useful.
And comments were somewhat outdated. Also added an explanation about
chosen order for the `INDEX_ID_<IDTYPE>` order.
