Problem: chain complete does not work when 'cot' includes fuzzy
and 'completefuzzycollect' collects wrong next word.
(Konfekt)
Solution: compl_startpos is not set correctly, remove next word check
in search_for_fuzzy_match (glepnir).

Problem: Strange error with type for matchfuzzy() "camelcase".
Solution: Show the error "Invalid value for argument camelcase" instead
of "Invalid argument: camelcase" (zeertzjq).
Note that using tv_get_string() will lead to confusion, as when the
value cannot be converted to a string tv_get_string() will also give an
error about that, but "camelcase" takes a boolean, not a string. Also
don't use tv_get_string() for the "limit" argument above.

Problem: When searching for "Cur", CamelCase matches like "lCursor" score
higher than exact prefix matches like Cursor, which is
counter-intuitive (Maxim Kim).
Solution: Add a 'camelcase' option to matchfuzzy() that lets users disable
CamelCase bonuses when needed, making prefix matches rank higher.

Problem: The current_pos.col was incorrectly updated to the length of
the matching text. This will cause the next search to start
from the wrong position.
Solution: current_pos has already been updated in search_str_in_line and

Problem: potential out-of-memory issue in search.c
Solution: improve situation and refactor search.c slightly
(John Marriott)
- In function update_search_stat():
add a check for a theoretical null pointer reference, set and remember
the length of lastpat, remove the three calls to STRLEN() and use the
various string's associated lengths instead, add a check for an
out-of-memory condition.
- In function search_for_fuzz_match():
remove a call to strnsave() and thus avoid having to add a check for
an out-of-memory condition, also replace the call to STRLEN() by
ml_get_buf_len().

Problem: Option metadata like list of valid values for an option and
option flags are not listed in the `options.lua` file and are instead
manually defined in C, which means option metadata is split between
several places.
Solution: Put metadata such as list of valid values for an option and
option flags in `options.lua`, and autogenerate the corresponding C
variables and enums.

Problem: Highlight group id is not propagated to the end of the message call
stack, where ext_messages are emitted.
Solution: Refactor message functions to pass along highlight group id
instead of attr id.
while the implementation is not tied to screen chars, it is a reasonable
expectation to support the same size. If nvim is able to display a
multibyte character, it will accept the same character as input,
including in normal mode commands like r{char}

clusters from recent unicode versions.
Handle variant selector VS16 turning some codepoints into double-width

possible.

Keep functions related to wildcard expansion in path.c, as in Vim they
are now spread out among multiple files, which isn't really ideal.
This also makes shada reading slightly faster due to avoiding
some copying and allocation.
Use keysets to drive decoding of msgpack maps for shada entries.
Problem:
Variables are often assigned multiple places in common patterns.
Solution:
Replace these common patterns with different patterns that reduce the
number of assignments.
Use `MAX` and `MIN`:
```c
if (x < y) {
x = y;
}
// -->
x = MAX(x, y);
```
```c
if (x > y) {
x = y;
}
// -->
x = MIN(x, y);
```
Use ternary:
```c
int a;
if (cond) {
a = b;
} els {
a = c;
}
// -->
int a = cond ? b : c;
```
Problem: Current instance of last search pattern not easily spotted.
Solution: Add CurSearch highlighting. (closesvim/vim#10133)

Problem: More code can use ml_get_buf_len() instead of STRLEN().
Solution: Change more STRLEN() calls to ml_get_buf_len(). Also do not
set ml_line_textlen in ml_replace_len() if "has_props" is set,
because "len_arg" also includes the size of text properties in
that case. (zeertzjq)

Problem: qsort() comparison functions should be transitive
Solution: Do not subtract values, but rather use explicit comparisons
Improve qsort() comparison functions
There has been a recent report on qsort() causing out-of-bounds read &
write in glibc for non transitive comparison functions
https://www.qualys.com/2024/01/30/qsort.txt
Even so the bug is in glibc's implementation of the qsort() algorithm,
it's bad style to just use substraction for the comparison functions,
which may cause overflow issues and as hinted at in OpenBSD's manual
page for qsort(): "It is almost always an error to use subtraction to
compute the return value of the comparison function."
So check the qsort() comparison functions and change them to be safe.

Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
