Problem: There is no way to get the definition of a builtin or a user
defined function, of an Ex command, of an option or of a v:
variable from Vim script. A language server has to parse the
help text or the output of ":function" and ":command" for it.
Solution: Add getinfo({kind}, {name} [, {opts}]), which returns a Dict
with the definition of {name}: a function, an Ex command, an
option or a v: variable. Keep the names of the arguments of
the builtin functions in their table and report them in
"args" (Hirohito Higashi).

Problem: Vim Syntax Script can be improved
Solution: Rework syntax script, update syntax tests and unit tests

- Contain Ex commands to valid syntactic contexts.

Use :syn-keyword to match all commands except when immediately following
\w range characters where :syn-match is employed.

Problem: Cannot render images in popup windows
Solution: Add support for rendering images using the kitty, sixel, cairo
and GDI backend (Yasuhiro Matsumoto).
Add an "image" attribute to popup_create()/popup_setoptions() that
renders a raw RGB/RGBA pixel buffer inside a popup window. Terminal
backends emit the buffer as DEC sixel or kitty graphics sequences; the
MS-Windows GUI uses GDI and the GTK GUI uses Cairo. The popup auto-sizes
its cell box from the image dimensions. getbgcolor() returns the current
background colour so scripts can pre-composite RGBA pixels.

Problem: Since v9.2.0349, the vertical separator cell at status line
rows is drawn as a space with StatusLine highlight, hiding the
user's 'fillchars' "vert" or "stl"/"stlnc" character at that
cell (after v9.2.0349)
Solution: Drop the status line blend. At status line rows the separator
cell goes back to using the status fillchar when adjacent
status lines are connected, or the vsep character otherwise.
(Same as before v9.2.0348)
Keep the VertSplitNC highlight group introduced in v9.2.0349. The
highlight (VertSplit vs VertSplitNC) is selected based on whether the
current window is adjacent to the separator at the row.
Vertical separators are redrawn on current-window changes and on
:redrawstatus[!] so the VertSplit/VertSplitNC highlight is updated
immediately.

Solution: Add tabpanel_getinfo() and tabpanel_scroll()

tabpanel_getinfo() returns a dict describing the tabpanel (align,
columns, scrollbar, offset, total, max_offset).
tabpanel_scroll(n) scrolls the tabpanel by n rows (positive for
down, negative for up). With {absolute: 1} the argument is used as
the new absolute offset instead of a delta. The offset is clamped to
the valid range; returns true when it actually changes.

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: Vim can only act as a channel client (ch_open). There is
no way for an external process to initiate a connection
to a running Vim instance using the Channel API.
Solution: Implement ch_listen() and the underlying server-side
socket logic. This allows Vim to listen on a port or
Unix domain socket. When a client connects, a new
channel is automatically created and passed to a
user-defined callback (Yasuhiro Matsumoto).

Problem: completion: complete_match() Vim script function and
'isexpand' option are not that useful and confusing
(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
endfor
return result
endfunc
