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.
- `_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.
Essentially, our current code would not properly remove (dereference)
its python objects matching various RNA data created during execution.
Some cases are fairly trivial to understand (like the lack of handling
of unregstering for our 'startup' operators and UI), other were more
subtle (like unregistered PropertyGroups who would remove/free their RNA
struct definition, without releasing first the potential matching python
object).

Accessing `bl_rna` for type defined in `scripts/modules/bpy_types.py`
could return their parent-classes RNA when accessed via their parent
types __subclasses__() method.
This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.

Support for "System" extensions as an alternative to the current
"User" extensions repository.
The purpose of this change is to support bundling extensions for
offline work or in environments where users setting up thier own
extensions isn't desirable, see #122512.
Details:
The default "System" repository on Linux will for example use:
- `/usr/share/blender/4.2/extensions/{system}` For system installs.
- `./4.2/extensions/{system}` For portable installs.
- Blender's default startup now has a "System" repository
which users or administrators may populate.
- Repositories can select between User/System paths,
setting a custom path overrides overrides this setting.
- Add "BLENDER_SYSTEM_EXTENSIONS" (matching "BLENDER_LOCAL_EXTENSIONS").

Add _bpy._wm_capabilities(), needed for preferences code to check if
WM functionality is supported. This could be made into a public
function, see code comments for details.
Replace: `{BLENDER_RESOURCE_PATH_USER}/extensions`
With: `{BLENDER_USER_EXTENSIONS}`
This follows BLENDER_USER_CONFIG & BLENDER_USER_SCRIPTS conventions.
Reading the environment variable and accessible via
`bpy.utils.user_resource('SCRIPTS')`
This was only used on WIN32 when the temporary directory didn't exist.
When the check was added [0] this made some sense because it relied on
`U.tempdir` existing, since then additional checks have been added to
ensure a temporary directory can be used. Further, this fall-back
location isn't documented in the user manual.

Add support for add-ons to define commands using the new argument
`-c` or `--command`.
Commands behave as follows:
- Passing in a command enables background mode without the need to pass
in `--background`.
- All arguments following the command are passed to the command
(without the need to use the `--` argument).
- Add-ons can define their own commands via
`bpy.utils.register_cli_command` (see examples in API docs).
- Passing in `--command help` lists all available commands.
Ref !119115
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.

- 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.
