This significantly simplifies memory management, mostly by avoiding
the need to free the memory manually. It may also improve performance,
since std::string has an inline buffer that can prevent heap
allocations and it stores the size.

The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

No functional changes expected.
Before this PR the keyframing code was aware of driver specifics
and changed the frame where a key is inserted to the current driver value.
This is now changed so that the calling code needs to know where on the
FCurve the key should be inserted. This removes the need for the
`INSERTKEY_DRIVER` flag.

The FPS menu was using a cached value which wasn't being refreshed
when translation changed.
Add `bpy.app.handlers.translation_update_post` handler which runs
when translation changes, this can be used to clear any cached UI
values.
Ref !117049
Using screen changing functions with screens used for full screen areas
isn't supported & caused corrupt screen data.
Add checks that the current and overriding screen support switching,
raising an error when they don't. Also add a check when restoring the
context not to change any full screen areas.
Recent and ongoing efforts have changed many properties to be stored
contiguously in memory, e.g. mesh attributes. This patch updates
rna_raw_access to make use of this and copy the entire contiguous block
of memory when the property is stored contiguously.
This is faster and scales much better with larger arrays.
Pull Request: https://projects.blender.org/blender/blender/pulls/116015
The foreach_get/foreach_set methods of bpy_prop_array get/set the entire
contents of the array, but they were checking that the length of the
input sequence was equal to the length of the current array dimension
rather than the total length of all dimensions of the array.
This would read/write memory after the end of the passed in sequence
when the property was a multidimensional array. Performing
`foreach_get` with a Python list with length matching the length of the
current dimension of a multidimensional array would crash a debug build
due to the trailing pad bytes of the temporarily allocated array being
overwritten.
This patch fixes `pyprop_array_foreach_getset` by changing the function
used to get the expected sequence size, to the RNA function that gets
the total length of the array across all its dimensions.
The tests have be updated to additionally test multidimensional array
properties.

Translation of the UI is currently split into 3 preferences:
interface, tooltips, and new data. The distinction between interface
and tooltips is currently unclear as tooltips also include a lot of
messages not displayed in the actual tooltips on mouse hover.
These include reports to the Info Editor, information in editor
headers and footers, and statuses in panels.
In order to limit the use of `TIP_()` to actual tooltips, this commit
introduces a new preference for this extra information: "Reports".
New translation macros are introduced: `RPT_()` and `CTX_RPT_()`, as
well as their equivalent for the Python API, `pgettext_rpt_()`, to be
imported as `rpt_()`.

RNA raw types were missing for the int8_t, uchar (uint8_t),
ushort (uint16_t), int64_t and uint64_t DNA types types.
This adds the missing RNA raw types for all DNA types that can have
raw access.
Functional Changes
Properties with one of the new unsigned raw types will raise a Python
OverflowError in foreach_getset when attempting to read a negative
integer from bpy_prop_collection.foreach_set(). This is similar to the
existing behaviour of providing a Python int which is too large to
represent as a C long. The existing foreach_getset code will print
the OverflowError and then raise a TypeError instead.
CPython's signed integer parsing functions accept numeric types that are
not the Python int instances by calling their __index__() method.
CPython's unsigned integer parsing functions, however, only accept
Python int instances. To make foreach_getset accept the same
numeric types for unsigned raw types as it already accepts for signed
raw types, the unsigned integer parsing functions in py_capi_utils.h
have been updated to also call the __index__() method when given an
argument which is not a Python int instance.
Because the new unsigned integer parsing in foreach_getset is using
the PyC_ family of functions, which perform their own overflow checks,
the existing signed integer parsing has also been updated to use the
PyC_ family of functions for signed integer parsing. Previously,
OverflowError would only have been raised when the parsed integer was
too large to fit in a C long. With this patch, OverflowError will be
raised whenever the parsed integer is too large to fit in the property's
raw type. Integer properties already have well-defined maximum and
minimum values which should fit within the property's raw type, and enum
properties have a fixed number of values they can take depending on
their items. The bigger change here, is that setting bool properties
which use PROP_RAW_BOOLEAN will now only accept 0/False and
1/True.
Now that PROP_RAW_CHAR parsing is using PyC_Long_AsU8,
signed char buffers ("b" format) have been updated to no longer be
considered compatible with PROP_RAW_CHAR, matching the behaviour of
the other unsigned types only being considered compatible with unsigned
buffer formats.
The int64_t and uint64_t types can currently only be used by bool
properties (see IS_DNATYPE_BOOLEAN_COMPAT and the other macros in
RNA_define.hh), but bool properties only have raw access when they do
not use a bitmask and it doesn't make much sense to use an entire 64
bits just for a single bool property, so PROP_RAW_INT64 and
PROP_RAW_UINT64 are expected to be unused.
Performance Changes
Providing raw types allows for faster access through
rna_access.cc#rna_raw_access, especially when a buffer compatible with
the property's raw type is passed through from
bpy_rna.cc#foreach_getset.
Before this patch, the bpy.types.Keyframe.handle_left_type property
did not have raw access, so foreach_getset would fall back to
PROP_RAW_INT being the compatible type and then use the slower loop in
rna_raw_access.
With this patch, the bpy.types.Keyframe.handle_left_type property has
raw access with the PROP_RAW_UINT8 type. Using a buffer compatible
with this raw type can use the faster memcpy loop in
rna_raw_access. Using a Python list will iterate the list into an
array whose type matches PROP_RAW_UINT8, which will also use the
faster memcpy loop in #rna_raw_access.

The functions for creating bpy vector properties used fixed size
`default_value` arrays on the stack. The array was not large enough to
store all the default values for larger multidimensional properties,
which would write past the end of the array and start corrupting the
stack, leading to crashes.
The maximum total length of a bpy vector property is 32768 (32x32x32)
which is a little large of an array to be putting on the stack, so the
`default_value` array now uses `blender::Array` and allocates additional
memory if the number of `default_value` elements exceeds its inline
buffer size of 64.
To simplify allocating arrays of the correct size,
#bpy_prop_array_length_parse now fills in `array_len_info->len_total`
when parsing a sequence.

As discussed in #105407, it can be useful to support returning
a fallback value specified by the user instead of failing the driver
if a driver variable cannot resolve its RNA path. This especially
applies to context variables referencing custom properties, since
when the object with the driver is linked into another scene, the
custom property can easily not exist there.
This patch adds an optional fallback value setting to properties
based on RNA path (including ordinary Single Property variables
due to shared code and similarity). When enabled, RNA path lookup
failures (including invalid array index) cause the fallback value
to be used instead of marking the driver invalid.
A flag is added to track when this happens for UI use. It is
also exposed to python for lint type scripts.
When the fallback value is used, the input field containing
the property RNA path that failed to resolve is highlighted in red
(identically to the case without a fallback), and the driver
can be included in the With Errors filter of the Drivers editor.
However, the channel name is not underlined in red, because
the driver as a whole evaluates successfully.

In order to prepare for introduction of fallbacks, refactor the
function to return its status as an enumeration value. Also, move
the index range check inside the function from python-specific code.
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.
When overriding the contexts window but not the screen, the context
override would attempt to use the current screen with the new window.
This raised an error and could crash when editing properties in the
key-map editor for the "context toggle" operator.
All the relevant code is C++ now, so we don't need to complicate things
with the trip through C anymore. We will still need some wrappers, since
opensubdiv is an optional dependency though. The goal is to make it
simpler to remove the unnecessary/costly abstraction levels between
Blender mesh data and the opensubdiv code.
The recent addition screen override [0] failed to account for the
override windows screen being overridden when restoring the context.
When overriding the window and screen, it's incorrect to use the
original contexts screen when restoring the screen of the overriding
window.
This window's screen may not be in the original context or the
overriding screen. Resolve the bug by storing this separately
and use it when restoring the context.

Adds initial support for File Handler registration with the python API
for design task #68935. File Handlers will allow developers to associate
additional UI behavior and capability to operators traditionally used
only within the file browser.
The initial commit should have no user visible changes, but will serve
as the foundation for providing file drag & drop capabilities to
operators that can manage files (#111242).
See the PR for an example of python usage.
See design task #68935 for remaining work to be explored in the future.

Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

Subtle regression in [0] caused context override to fail when
passing in the current context when a temporary screen was used.
While passing in a temporary screen as an override isn't supported,
this shouldn't raise an exception if the argument matches the current
context.
Also added sanity check that the window passed in exists
and code comments to give an explanation of the current behavior.
