Problem: cannot style non-current window separator
Solution: Add the VertSplitNC highlighting group
(Hirohito Higashi).
Add VertSplitNC highlight group for vertical separators of non-current
windows, similar to StatusLine/StatusLineNC distinction. The separator
adjacent to the current window uses VertSplit, others use VertSplitNC.
Default: linked to VertSplit.
At the current window's status line rows, the separator cell is drawn as
a space with the StatusLine highlight so it blends into the status line
without a stray fillchar glyph.
Also:
- :redrawstatus[!] now also redraws vertical separators.
- statusline height changes trigger vsep redraw.

Problem: popup: still opacity rendering issues
Solution: Fix remaining issues, see below
(Yasuhiro Matsumoto).
This PR fixes the following issues:
- Padding blend hole at wide char boundary: when a padding cell overlaps
the second half of a wide character, the right half's attr value is
unreliable. Use the left half's saved attr for blending instead.
- Wide char background split at popup boundary: when a wide character in
an upper popup straddles the edge of a lower opacity popup, both
halves got different background colors. Since terminals cannot render
different left/right background colors for a wide character, detect
the lower popup with popup_is_over_opacity() and use the non-popup
side's underlying attr for both halves.
- Wrong blend color with cterm-only highlights under 'termguicolors':
when a popup highlight has ctermbg but no guibg, bg_rgb is set to
CTERMCOLOR (not INVALCOLOR). hl_blend_attr() used this value as a real
RGB color, producing gray instead of the intended color. Use
COLOR_INVALID() to detect both INVALCOLOR and CTERMCOLOR, and fall back
to converting the cterm color number to RGB.

Problem: too many strlen() calls
Solution: refactor concat_fname() and remove calls to strlen()
(John Marriott)
Function `concat_fnames()` can make up to 5 calls to `STRLEN()` (either
directly or indirectly via `STRCAT()`). In many cases the lengths of
arguments `fname1` and/or `fname2` are either known or can simply be
calculated.
This Commit refactors this function to accept the lengths of arguments
`fname1` and `fname2` as arguments. It also adds new argument `ret` to
return the resulting string as a `string_T`.
Additionally:
- function `add_pack_dir_to_rtp()` in `scriptfile.c`:
Use a `string_T` to store local variables `new_rtp` and `afterdir`.
Replace calls to `STRCAT()` with calls to `STRCPY()`.
Change type of variable `keep` to `size_t` for consistency with
other lengths.
- function `qf_get_fnum()` in `quickfix.c`:
Use a `string_T` to store local variables `ptr` and `bufname`
- function `qf_push_dir()` in `quickfix.c`:
Use a `string_T` to store local variable `dirname`.
Replace call to `vim_strsave()` with `vim_strnsave()`.
- function `qf_guess_filepath()` in `quickfix.c`:
Use a `string_T` to store local variable `fullname`.
- function `make_percent_swname()` in `memline.c`:
Rename some variables to better reflect their use.
Use a `string_T` to store local variables `d` and `fixed_name`.
Slightly refactor to remove need to create an extra string.
- function `get_file_in_dir()` in `memline.c`:
Use a `string_T` to store local variables `tail` and `retval`.
Move some variables closer to where they are used.
- function `cs_resolve_file()` in `if_cscope.c`:
Use a `string_T` to store local variable `csdir`.
Remove one call to `STRLEN()`.
- function `add_pathsep()` in `filepath.c`:
Refactor and remove 1 call to `STRLEN()`
- function `set_init_xdg_rtp()` in `option.c`:

Problem: close_buffer() callers incorrectly handle b_nwindows,
especially after nasty autocmds, allowing it to go
out-of-sync. May lead to buffers that can't be unloaded, or
buffers that are prematurely freed whilst displayed.
Solution: Modify close_buffer() and review its callers; let them
decrement b_nwindows if it didn't unload the buffer. Remove
some now unneeded workarounds like 8.2.2354, 9.1.0143,
9.1.0764, which didn't always work (Sean Dewar)
close_buffer() now doesn't decrement b_nwindows when not unloading buf, or when
buf isn't w_buffer after autocmds (they would've already decremented it).
Callers are now expected to decrement b_nwindows if w_buffer is not NULL after
close_buffer(), and when still intending to switch buffers or close win, for two
reasons:
- close_buffer() autocmds may have switched buffers. The new w_buffer's
b_nwindows would also need decrementing.
- After close_buffer(), callers may opt to not switch w_buffer or close win.
b_nwindows would need to be incremented again. (unless w_buffer is NULL from
being unloaded; callers are already forced to find a new buffer then)
These were the main causes of b_nwindows bugs, as these cases could not be
reliably detected, and went largely unhandled.
NOTE: if close_buffer() autocmds switch buffers, close_buffer() is not called
for that new buffer before decrementing b_nwindows. This may skip side-effects
like from 'bufhidden', but I think it's mostly harmless, and was already
happening in other places.
Let's see how this goes... Other details: (I have lots to say!)
It's OK to pass a win to close_buffer() that isn't showing buf (used by
set_curbuf()). In that case, we skip some side-effects and don't decrement
b_nwindows, but may still unload buf if hidden.
buf_freeall() now returns whether it freed anything. Removes some repeated
checks in close_buffer().
Preserve close_buffer()'s behaviour when called by win_free_popup() after its
popup was already removed from the window list. This made win_valid_any_tab()
return FALSE, so we skip things that originally checked it in that case.
Add "set_context" to close_buffer() to preserve do_ecmd()'s behaviour of only
setting b_last_cursor and/or calling buflist_setfpos() when not splitting
(see 7.2.041: https://groups.google.com/g/vim_dev/c/ZGgNvaylNzI/m/WHxjhnuxqB0J)
Without this, Test_marks_cmd() fails from its ' mark differing. Don't use
oldwin though; it's not always the window with the closed buf, especially
after BufLeave autocmds in do_ecmd(). Also, only set context if win is really
displaying buf.
Don't bail in do_ecmd() if buf was deleted but curwin->w_buffer is NULL; that
leaves curwin open to a NULL buffer! Use lastbuf instead, like set_curbuf().
I don't think it's possible for buf to be deleted by close_buffer() anyway, as
b_locked was set (which I can't see a way to bypass, unlike b_locked_split).
Maybe such checks can be removed, but I'd rather not risk that here.
Don't set curwin to previouswin in set_curbuf(); shouldn't be needed, otherwise
may lead to curbuf != curwin->w_buffer if autocmds switch to a window showing
buf, as that skips enter_buffer()? Was introduced back in 7.3.557 to avoid
cases where autocmds switch windows, possibly leaving previouswin with a NULL
buffer. Since 7.4.2312 and 7.4.2328, close_buffer() and buf_freeall() already
handles this. I've added an assert() as a sanity check anyway.
In free_all_mem(), set b_nwindows to 0 before close_buffer() so buffers can be
wiped if still in a window before win_free_all(). Needed as close_buffer() now
skips unloading buffers that aren't hidden if win is NULL. If it's possible for
free_all_mem()'s :tabonly! and :only! to not close all windows before freeing,
then this issue was also previously possible if b_nwindows > 1.

Problem: Use-after-free in winframe_remove() (henices)
Solution: Set window_layout_locked() inside winframe_remove()
and check that writing diff files is disallowed when the
window layout is locked.
It can happen with a custom diff expression when removing a window:
1. Buffer was removed, so win_frame_remove() is called to remove the
window.
2. win_frame_remove() → frame_new_height() → scroll_to_fraction()
→ diff_check_fill() (checks for filler lines)
3. diff_check_fill() ends up causing a diff_try_update, and because we
are not using internal diff, it has to first write the file to a
buffer using buf_write()
4. buf_write() is called for a buffer that is not contained within a
window, so it first calls aucmd_prepbuf() to create a new temporary
window before writing the buffer and then later calls
aucmd_restbuf(), which restores the previous window layout, calling
winframe_remove() again, which will free the window/frame structure,
eventually freeing stuff that will still be accessed at step 2.

Problem: completion: complete_match() Vim script function and

(after v9.1.1341)
Solution: Remove function and option and clean up code and documentation
(Girish Palya).
complete_match() and 'isexpand' add no real functionality to Vim. They
duplicate what `strridx()` already does, yet pretend to be part of the
completion system. They have nothing to do with the completion mechanism.
* `f_complete_match()` in `insexpand.c` does not call any completion code.
It’s just a `STRNCMP()` wrapper with fluff logic.
* `'isexpand'` exists only as a proxy argument to that function.
It does nothing on its own and amounts to misuse of a new option.
The following Vim script function can be used to implement the same
functionality:
```vim
func CompleteMatch(triggers, sep=',')
let line = getline('.')->strpart(0, col('.') - 1)
let result = []
for trig in split(a:triggers, a:sep)
let idx = strridx(line, trig)
if l:idx >= 0
call add(result, [idx + 1, trig])
endif
