Python API functions would both report an error through CLOG and throw an
exception. However this is a problem when --debug-exit-on-error is used,
as tests and other scripts will not have the opportunity to catch the exception
before Blender exits.
Now don't print such reports through CLOG. Note that these usages of
BKE_reports_init have their print level set to error, so were already not
printing info and warning reports (which is not something we generally
want Python API calls to do, they should be silent).

Python 3.14 has moved some functionality into the public API,
use the updated names even with older Python versions.
Also resolve an error caused by variable reuse with delayed annotation
evaluation for TextureProperties_MixIn on startup.
Resolve#140695.
When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.

Replace plain-text type information with the type syntax used
for Python's type annotations as it's more concise, especially for
callbacks which often didn't include useful type information.
Note that this change only applies to inline doc-strings,
generated doc-strings from RNA need to be updated separately.
Details:
- Many minor corrections were made when "list" was incorrectly used
instead of "sequence".
- Some type information wasn't defined in the doc-strings and has been
added.
- Verbose type info would benefit from support for type aliases.
For now, PointerRNA is made non-trivial by giving explicit default
values to its members.
Besides of BPY python binding code, the change is relatively trivial.
The main change (besides the creation/deletion part) is the replacement
of `memset` by zero-initialized assignment (using `{}`).
makesrna required changes are quite small too.
The big piece of this PR is the refactor of the BPY RNA code.
It essentially brings back allocation and deletion of the BPy_StructRNA,
BPy_Pointer etc. python objects into 'cannonical process', using `__new__`,
and `__init__` callbacks (and there matching CAPI functions).
Existing code was doing very low-level manipulations to create these
data, which is not really easy to understand, and AFAICT incompatible
with handling C++ data that needs to be constructed and destructed.
Unfortunately, similar change in destruction code (using `__del__` and
matching `tp_finalize` CAPI callback) is not possible, because of technical
low-level implementation details in CPython (see [1] for details).
`std::optional` pointer management is used to encapsulate PointerRNA
data. This allows to keep control on _when_ actual RNA creation is done,
and to have a safe destruction in `tp_dealloc` callbacks.
Note that a critical change in Blender's Python API will be that classes
inherinting from `bpy_struct` etc. will now have to properly call the
base class `__new__` and/or `__init__`if they define them.
Implements #122431.

- `_PySet_NextEntry` has been removed, use generic iterator access
which will has some additional overhead as it needs to create
an iterator to access the values.
- Add v3.13 compatibility defines to account for renaming:
_PyObject_LookupAttr -> PyObject_GetOptionalAttr
_PyLong_AsInt -> PyLong_AsInt
- Unfortunately use of Python's internal API needs to be used to
inspect op-codes in `bpy_driver.cc`.
Testing GLTF/FBX IO there isn't any significant performance impact
from these changes.
Resolves#123871.
BPY `library.write` has been moved to new PartialWriteContext code a few
weeks ago, removing this call to `BKE_blendfile_write_partial_end` was
somehow missed then.
This makes code behind the `bpy.data.libraries.write()` API use the new
`PartialWriteContext` class, instead of the old
`BKE_blendfile_write_partial` API.
NOTE: This also means that the `blendfile_io` tests using this python
API are now using the new class.
No behavioral changes are expected here.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
This commit makes using (most of) `BKE_report` API safe in
multi-threaded situation.
This is achieved by adding a `std::mutex` lock to the `ReportList`
struct (in a slightly convoluted way unfortunately, due to this being a
DNA struct). This lock is then used to make most operations on
`Reportlist` data thread-safe.
Note that while working on this, a few other minor issues aroze in
existing usages of Reportlist by the WM code, mainly the fact that
`wm_init_reports` and `wm_free_reports` were both useless:
- init was called in a context where there is not yet any WM, so it
was doing nothing.
- free was called on a WM that would be later freed (as part of Main
freeing), which would also call cleanup code for its `reports` data.
Both have been removed.
Further more, `wm_add_default` (which is the only place where a WM ID is
created) did not initialize properly it reports data, this has been
fixed.
This change is related to the wmJob thread-safety tasks and PRs (#112537,
!113548).

- Account for new member in _PyArg_Parser.
- Many Python op-codes have been removed.
For the moment these are disabled in is_opcode_secure.
Some should be added back as intrinsics, noted in code-comments.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Use PyC_ParseUnicodeAsBytesAndSize parser instead of "s" / "z" type
specifier. This relates to #111033, resolving Python exceptions which
causes icons not to load (for e.g.).
Now bytes are also supported as path arguments.
While these warnings point to real errors in the code,
PyMethodDef are an exception where functions with different numbers
of arguments are all cast to the same function type.
