This patch updates the documentation for arguments regarding the `Gizmo`
type.
- Corrected `select_id` doc for draw_preset_ functions. `-1` indicates
that no selection ID is to be written, but previous docs incorrectly
specified `0` instead.
- Added missing doc for `target` argument for `target_set_handler`
function.

Add internal function (only used for testing at the moment)
`_bpy._driver_secure_code_test`.
Add test `script_pyapi_bpy_driver_secure_eval` to serves two purposes:
- Ensure expressions that should be insecure remain so when upgrading
Python or making any changes in this area.
- Ensure new versions of Python don't introduce new byte-codes that
prevent existing expressions from being executed
(happened when upgrading from 3.7, see [0]).
[0]: dfa5201763
The following opcodes have been added, see [0] for details:
- LIST_TO_TUPLE: convert a list to a tuple,
use for constructing lists/tuples in some cases.
- LIST_EXTEND: use for constructing lists with unpacking.
- SET_UPDATE: use for constructing sets with unpacking.
- CONTAINS_OP: check if `a in b` generally useful.
When writing tests these op-codes where needed for basic operations
and can be safely supported.
Add note why dictionary manipulation op-codes have been left out.
Also restrict namsepace access to anything with an underscore prefix
since these may be undocumented.

Showing the expression alone may not be enough to track down an error

- Use API calls to access frame-data as PyFrameObject is now opaque.
- Update opcodes allowed for safe driver evaluation.
**Details**
Some opcodes have been added for safe-driver evaluation.
Python 3.11 removes many opcodes - the number of accepted opcodes in
Blender's listing dropped from 65 to 43) however some new opcodes
also needed to be added. As this relates to security details about newly
added opcodes have been noted below (see [0] for full documentation).
Newly added opcodes:
- CACHE:
Used to control caching instructions.
- RESUME:
A no-op. Performs internal checks.
- BINARY_OP:
Implements the binary and in-place operators,
replacing specific binary operations.
- CALL, PRECALL, KW_NAMES:
Used for calling functions, replacing some existing opcodes.
- POP_JUMP_{FORWARD/BACKWARD}_IF_{TRUE/FALSE/NONE/NOT_NONE}.
Manipulate the byte-code counter.
- SWAP, PUSH_NULL.
Stack manipulation.
Resolves T99277.

New opcodes added since 3.7 meant some actions such as `len()`
were disabled in safe py-driver execution.
The following opcodes have been added, see [0] for details:
- ROT_FOUR: similar to existing ROT_* opcodes, added v3.8.
- ROT_N: similar to existing ROT_* opcodes, added v3.10.
- GET_LEN: Push len(TOS) onto the stack, added v3.10.
- IS_OP: for ternary operator, added v3.9.
- BUILD_SLICE: access `slice` built-in, doesn't expose new
functionality beyond existing `__getitem__` access.

Blender wouldn't start with Python 3.11 because of an error in

The following CMake options have been added (enabled by default),
except for the lite build configuration.
- WITH_IO_STL
- WITH_IO_WAVEFRONT_OBJ
- WITH_IO_GPENCIL (for grease pencil SVG importing).
Note that it was already possible to disable grease pencil export
by disabling WITH_PUGIXML & WITH_HARU.
This is intended to keep the lite builds fast and small for building,
linking & execution.

Ref D15141
Main motivation is from T54314 where there was no way to read from a
Viewer image datablock after the compositor has run.
The only solution there was to do a full rerender (which obviously takes
much longer). Adding a handler avoids having to rerender.
This uses new syntax from rBf4456a4d3c97 and also adds "COMPOSITE" as a
job type that can be queried by `bpy.app.is_job_running`.
NOTE: there is another issue when multiple viewers are used and these
get active via RNA (compo execution is not triggered there yet -- unlike
when a viewer is selected in the Editor -- this is an issue of
`ED_node_set_active` vs. only `nodeSetActive`, but this will be tackled
separately)

Add `bpy.app.is_job_running(job_type)` as high-level indicator. Job
types currently exposed are `WM_JOB_TYPE_RENDER`,
`WM_JOB_TYPE_RENDER_PREVIEW`, and `WM_JOB_TYPE_OBJECT_BAKE`, as strings
with the `WM_JOB_TYPE_` prefix removed. The functions can be polled by
Python code to determine whether such background work is still ongoing
or not.
Furthermore, new app handles are added for
`object_bake_{pre,complete,canceled}`, which are called respectively
before an object baking job starts, completes sucessfully, and stops due
to a cancellation.
Motivation: There are various cases where Python can trigger the
execution of a background job, without getting notification that that
background job is done. As a result, it's hard to do things like
cleanups, or auto-quitting Blender after the work is done.
The approach in this commit can easily be extended with other job types,
when the need arises. The rendering of asset previews is one that's
likely to be added sooner than later, as there have already been
requests about this.

Currently strings are used for cases where a list of identifiers would
be useful to show.
Add support for string properties to reference a callback to populate
candidates to show when editing a string. The user isn't prevented from
typing in text not found in this list, it's just useful as a reference.
Support for expanding the following strings has been added:
- Operator, menu & panel identifiers in the keymap editor.
- WM operators that reference data-paths expand using the
Python-consoles auto-complete functionality.
- Names of keying sets for insert/delete keyframe operators.
Details:
- `bpy.props.StringProperty` takes an option `search` callback.
- A new string callback has been added, set via
`RNA_def_property_string_search_func` or
`RNA_def_property_string_search_func_runtime`.
- Addresses usability issue highlighted by T89560,
where setting keying set identifiers as strings isn't practical.
- Showing additional right-aligned text in the search results is
supported but disabled by default as the text is too cramped in most
string search popups where the feature would make sense. It could be
enabled as part of other layout tweaks.

When AUDASPACE couldn't find NUMPY, it would disable WITH_PYTHON for
the rest of Blender. Now setting the value globally is only done for
standalone AUDASPACE builds. Now it's possible to build Blender with
AUDASPACE & PYTHON but without NUMPY.
While this isn't an especially important configuration to support,
having Python mysteriously disabled is a hassle to troubleshoot.
NOTE: extern/audaspace/CMakeLists.txt has become out sync with the
original [0], it seems this is being maintained in our repository.

Accessing context members depended on `ctypes` to access symbols
which were hidden for macOS & WIN32.
Add an API call that doesn't require the symbols to be exported.
This allows most symbols to be hidden on Linux, see D14971.
`TEMPERATURE` type was also missing, not only the new-ish
`TIME_ABSOLUTE` one...
Added a static assert on the size of the `bpyunits_ucategories_items`
array, and a comment on anonymous enum of `B_UNIT_`, in the hope this
won't happen again in the future.
Regression caused by [0] that caused the error message to be
created based on a normalized exception (which hid line numbers).
PyC_ExceptionBuffer{_Simple} & BPy_errors_to_report
no longer clears the exception.
This could have been resolved by changing python_script_error_jump
however that would involve changes to reference counting that are more
risky (noted in code-comment).

Add missing check as the context override dict may have been copied
since it was assigned, also initialize the context manager with
PyType_Ready, while it didn't cause any errors - it's expected
that all types are initialized.
- Increase the stack level so the reported line number references
script authors code (not Blender's wrapper function).
- Include the operator name and poll/call usage in the warning.
Support a way to temporarily override the context from Python.
- Added method `Context.temp_override` context manager.
- Special support for windowing variables "window", "area" and "region",
other context members such as "active_object".
- Nesting context overrides is supported.
- Previous windowing members are restored when the context exists unless
they have been removed.
- Overriding context members by passing a dictionary into operators in
`bpy.ops` has been deprecated and warns when used.
This allows the window in a newly loaded file to be used, see: T92464
