Problem: potential buffer overrun in bufwrite.c
Solution: Use a temporary variable (John Marriott)
In my Windows 11 Pro 64-bit build MAXPATHL is 1024 and IOSIZE is 1025.
In my Archlinux Linux 64-bit build MAXPATHL is 4096 and IOSIZE is 1025.
In funuction buf_write():
There is a check (line 713) that makes sure the length of fname is less
than MAXPATHL. There is a call to STRCPY() (line 1208) which copies the
string at fname into IObuff (which has size IOSIZE). For Unix builds
fname is set to sfname which may or may not be shorter. However, if
sfname is NULL sfname is set to fname.
Therefore, in builds where MAXPATHL > IOSIZE (eg in my linux build), it
is theoretically possible for the STRCPY() call to exceed the bounds of
IObuff.
This PR addresses this by copying fname into a local variable that has
the same maximum size as fname.
In addition:
Given that the filename is unconditionally overwritten in the for loop,
only copy the directory portion of fname. Move variable i closer to
where it is used.

Problem:
with `foldmethod=expr foldexpr=v:lua.vim.treesitter.foldexpr()
foldminlines=0`, deleting lines at the end of the buffer always
reports an invalid top error, because the top value (i.e. the
start line number of the deletion) is always 1 greater than
the total line number of the modified buffer.
Solution:
remove the ml_line_count validation

Problem: on_detach may be called after buf_freeall and other important things,
plus its textlock restrictions are insufficient. This can cause issues such as
leaks, internal errors and crashes.
Solution: disable buffer updates in buf_freeall, before autocommands (like the
order after #35355 and when do_ecmd reloads a buffer). Don't do so in
free_buffer_stuff; it's not safe to run user code there, and buf_freeall already
runs before then; just free them to avoid leaks if buf_freeall autocommands
registered more for some reason.

Problem:
Buffer-updates on_detach callback is invoked before buf_freeall(), which
deletes autocmds of the buffer (via apply_autocmds(EVENT_BUFWIPEOUT,
...)). Due to this, buffer-local autocmds executed in on_detach (e.g.,
LspDetach) are not actually invoked.
Solution:
Call buf_updates_unload() before buf_freeall().

Problem: The :keep{alt,jumps,marks,patterns} commmands are sometimes
misidentified as :k.
Solution: Make sure one_letter_cmd() only returns true for :k and not
other :keep* commands (Doug Kearns).
This currently manifests as missing completion for :keep* commands and
incorrect results from fullcommand().
E.g., fullcommand("keepmarks") returns "k" rather than "keepmarks".
The correct command, however, is executed as command modifiers are
handled specially in do_one_cmd() rather than using find_ex_command().
Fix exists(':k') so that it returns 2 for a full match.

(cherry picked from commit 70bb7999f7)
When Nvim is started in one terminal emulator,
suspended, and later resumed in a different terminal emulator (as can
happen when using e.g. a multiplexer), the new terminal emulator will
not have all of the same modes enabled that the original terminal
emulator had. This is a problem in particular for in-band resize events
because we were disabling the SIGWINCH signal handler when we determined
that the terminal supported this mode.
However, if the new terminal does not support this mode then the
SIGWINCH handler remains disabled, and Neovim no longer properly
resizes. Instead of disabling the SIGWINCH handler, we track the state
of the resize events mode internally. If the mode is enabled then we
return early from the SIGWINCH handler before performing any ioctls or
other system calls. But if the mode is not enabled we proceed as normal.

Problem: :bnext doesn't go to unlisted help buffers when cycling
through help buffers (after 9.1.0557).
Solution: Don't check if a help buffer is listed (zeertzjq).
From <https://github.com/vim/vim/issues/4478#issuecomment-498831057>:
> I think we should fix that, since once you get to a non-help buffer
> all unlisted buffers are skipped, thus you won't encounter another
> help buffer.
This implies that cycling through help buffers should work even if help
buffers are unlisted. Otherwise this part of :bnext isn't really useful,
as :h makes help buffers unlisted by default.

Problem: Using `addr` without `range` in nvim_create_user_command gives

`:command` behavior.

Problem: Since 48e2a736, prompt messages are handled by an actual
active cmdline, resulting in `State` no longer being equal
to `MODE_CONFIRM` which is used in some places. E.g. to
specify the current `mode()` or to re-emit a confirm message.
Solution: Replace `MODE_CONFIRM` with a new `MODE_CMDLINE` sub-mode when
`ccline.one_key/mouse_used` is set. Use it to avoid clearing
mouse_used prompt messages, and to re-emit one_key messages
(when ext_messages is inactive, for which this is unnecessary).

Problem: The swapfile attention message is not repeated after clearing

After clearing the screen `msg_scrolled` is reset without

Problem:
The `nvim_get_keymap()` function is missing the `lhsrawalt` field in its response for mappings with an alternate key representation. This makes its return value inconsistent with its documented `maparg()`-like structure and its formal type definition.
Solution:
Corrects the `keymap_array` function to pass the alternate mapping keys (`current_maphash->m_alt->m_keys`) to `mapblock_fill_dict`. The argument responsible for this was previously hardcoded to `NULL`.
For example, for a mapping of `<C-x>`, the API will now correctly return both `lhsraw` (`<80><fc>^DX`) and `lhsrawalt` (the alternate form, e.g., `^X`).

Problem: When 'wildmode' is set to include "noselect", the popup menu (pum)
incorrectly retained its scroll position when reopened. This
meant that after scrolling down through the menu with `<C-n>`,
reopening the menu (e.g., by retyping the command and
triggering completion again) would show the menu starting from
the previously scrolled position, rather than from the top.
This could confuse users, as the first visible item would not
be the first actual match in the list.
Solution: Ensure that the popup menu resets its scroll position to the
top when reopened (Girish Palya).

(cherry picked from commit c925e7b8ba)
Problem:
The previous fix in #34314 relies on copying the tree in `tree_root` to
ensure the `TSNode`'s tree cannot be mutated. But that causes the
problem where two calls to `tree_root` return nodes from different
copies of a tree, which do not compare as equal. This has broken at
least one plugin.
Solution:
Make all `TSTree`s on the Lua side always immutable, avoiding the need
to copy the tree in `tree_root`, and make the only mutation point,
`tree_edit`, copy the tree instead.

Problem:
'exrc' files are inherently bound to their location / workspace and
therefore require to "know" their location on the filesystem. However,
currently using `debug.getinfo(1, 'S')` returns `"<nvim>"`.
Solution:
Include the filepath as chunkname in `loadstring()` and `nlua_exec()`.

Problem: Currently terminal highlight attribute buffers are statically allocated
be the size of `TERM_ATTRS_MAX`. This unique case isn't respected in
some places in the ui_compositor. Due to this, when a terminal window
has lines longer them `TERM_ATTRS_MAX`, the compositor will go past the
end of the buffer causing a crash due to out of bounds access.
Solution: Add check to ensure we don't query terminal highlight attrs
past `TERM_ATTRS_MAX` in `win_line()`.

Problem: On Windows, the value of `term` is overwritten without freeing
