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.
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.
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.

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

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.
When using menu search, each search item has multiple segments. In the UI,
we only highlight last section, which is the actual node/operator name. The
menu path is grayed out. It seems reasonable to give greater weight to the
words in the search item that are highlighted.
See #112839 for an example of what effect this can have.

The goal is to make the search faster to use by dynamically adapting to the user.
This can be achieved using the simple but common approach of showing recently
selected items at the top. Note, that the "matching score" between the query and
each search item still has precedence when determining the order. So the last used
item is only at the top, if there is no other search item that matches the query better.
Besides making the search generally faster to use, my hope is that this can also
reduce the need for manually weighting search items in some places. This is
because while the ordering might not be perfect the first time, it will always be
once the user selected the element that should be at the top once.
This patch includes:
* Support for taking recent searches into account in string searching.
* Keep track of a global list of recent searches.
* Store recent searches on disk similar to recently opened files.
* A new setting in the user preferences that allows disabling the functionality.
This can be used if deterministic key strokes are required, e.g. for automated tests.
In the future this could be improved in different ways:
* Add some kind of separator in the search list to indicate which elements are at
the top because they have been used recently.
* Store the recent search items per search, instead of in a global list. This way
it could adapt to the user even better.

Ensure the string isn't null terminated before len, if this happens
it's likely an error calculating the length argument. Since the length
is passed to memcpy it could result in reading outside `str` bounds.
There was one case where the string was duplicated then grew by 1 byte
afterwards. Replace this with an allocation since it's an uncommon
operation, not especially useful to support.
Make type conversions explicit so it's clear when char/char32_t/uint
values are being mixed, also use int instead of size_t for cursor
functions because the cursor is an int - which caused many int/size_t
comparisons.
This makes it clearer other "safe" functions should be used in
combination with the resulting offsets.
Also correct doc-string which wasn't updated from the "or_error()"
version of this function.
The functions used to calculate the UTF8 code-points already used the
safe versions (count_utf8_code_points & BLI_str_utf8_as_unicode_step).
So it makes sense to use safe accessors elsewhere too.
There were enough cases of callers ignoring a potential the error value,
using the column width for e.g. to calculate pixel sizes, or the size in
bytes to calculate buffer offsets.
Since text fields & labels can include characters that return an error
from BLI_str_utf8_as_unicode, add the suffix to make this explicit.
Strings that include Latin1 encoding or corrupt UTF8 byte sequences
could read past the buffer bounds (stepping over the null terminator).
Resolve by passing in the string length.
Other changes to support non-UTF8 byte sequences:
- BLI_str_utf8_offset_{to/from}_index were accumulating
the UTF8 offset without accounting for non-UTF8 characters
which could cause a buffer underflow or enter an eternal loop.
- BLI_str_utf8_offset_to_index would read past the buffer bounds if the
offset passed in if it was in the middle of a UTF8 byte sequence.
Change to handling of control characters in [0] caused tests to fail,
now the cursor no longer skips over control characters,
update test to account for this.
[0]: bc51449ff1
BLI_str_utf8_char_width returns -1 for character without a known width.
This caused the right cursor motion to skip these characters.
While editable text should not contain control characters,
cursor motion should behave properly in cases when they do.
