Set the "I/O error" if the result from read is larger than the requested
size, while unlikely - set the error so an error return always sets the
`errno`.

The clip_plane count in BLI_kdopbvh.c was incorrectly reduced.
To solve, make the size of the clip_plane array variable.
This eliminates the need to keep values in sync.
According to the documentation `read` isn't required to read all the
data requested. Although until recently I'd never encountered this and
none of Blender's code checks for read succeeding but not reading the
requested size.
Resolves#113473 where images over 2gb fail to load.
Ref !113474.
Remove unnecessary calls to BLI_file_descriptor_size when using
BLI_mmap_open since this stores the file size too.
While accessing the size twice isn't so bad, the additional check
that the file size isn't an error value is unnecessarily verbose.
Failure to seek would attempt to MMAP SIZE_T_MAX, while this would
likely fail, prefer an explicit error check instead of relying on
unreasonable requests to be rejected.
Accessing the file size returns -1 on error, for file packing this
was passed directly to an allocation which would wrap around to
SIZE_T_MAX and fail to allocate. In other cases zero was treated
as an error value but -1 wasn't.
Add checks for the error return value, also warn that packing files over
2gb isn't supported.
Use the typical combination of an "array utils" function used by an
attribute interpolation function. This helps moves us towards having
a more centralized implementaiton of attribute propagation that can
be changed and optimized more easily.
The function `BLI_findlinkfrom` returns the link that is n-steps
after the given start link. This did not work for negative steps.
This change makes it so that both positive and negative step
values work.
`iota` is name that has no meaning, it's not an acronym or initialism.
It's usually very cryptic when I come across it. Replacing it with a
specialized function makes the code more readible.
When using menu-search, only the last part of a search item is highlighted.
When sorting the search results, this should be taken into account and
the highlighted words should be prioritized.
This was already partially implemented in 56e98f8ba6. Now it's also
taken into account with prefix search. For example, `TC` now prefers
`Input > Texture Coordinate` over `Texture > Checker Texture`.
The idea is that accessing recent searches is mostly only useful when actually
searching for something very recent, which means that it would show up at the
top even if the query is empty or extremely short. If the user is typing a longer
query, it likely means that what is at the top is not what is actually desired, so
it's better to not take recent searches into account anymore.

This PR implements an initial drawing tool that can already be used for testing.
While this is not fully feature complete (compared to the current grease pencil draw tool) the following is already implemented:
* Pressure support for radius and opacity.
* Material color and vertex color support.
* New active smoothing algorithm based on curve fitting.
* Simplify algorithm as a post-process step.
Some deliberate limitations include:
* The drawing plane is always the front plane. Drawing on surfaces is also not supported.
*
The current approach has not been optimized for performance yet. The goal was to have a straightforward implementation
first and then focus on performance later.
There are numerous parameters in the code that are hard-coded for now. These should be exposed at some point, potentially as user settings.

This replaces the older dynamic c arrays with blender::Vector as
appropriate. Many files required minimal changes and the before/after
are quite similar.
There's 3 remaining usages of the old machinery but those will require
more involved changes and design.

Add frequently-used Chinese, Japanese, Korean special character
delimiters (punctuation, quote characters, brackets, etc) to aid the
selection of character segments in text operations.

This add the possibility to create a
orthogonal basis around a given unit
vector.
The name was chosen to match the naming
convention already in place and match
the other matrix construction functions.
In other places (ex: renderers), this same
function is commonly named `make_orthonormal`
or `make_basis`.
The function is not given to have a fixed
implementation and might change overtime.
That's why the test only covers the
assumptions and not the raw values.
The implementation is borrowed from
Cycles and adapted to our math API.

The logic to handle word selection from double clicking ran even when
the event wasn't inside the button. This would pass an invalid position
to BLI_str_cursor_step_bounds_utf8 which hung.
Resolve by limiting word-selection to when the event is inside
the text editing field as well as clamping the position to ensure
it's within the allowed range.
MSVC 17.7 generates bad code in some lambda's, this has been reported
upstream [1], and a workaround has been suggested by MS in the form of
turning the inliner off. In consultation with the geo nodes people this
was deemed a passable solution, there was only a single call to this
method so performance wasn't a concern, so no special care had to be
taken to single out just the problematic MSVC versions.
If this bug pops up in other parts of our code where performance IS a
concern a more delicate approach may be required.
