Problem: Setting 'winhighlight' doesn't after setting global namespace
using nvim_win_set_hl_ns().
Solution: Check if using another namespace when setting 'winhighlight'
instead of disabling 'winhighlight' in nvim_win_set_hl_ns().

Problem: Crash on failed sockconnect() if a new connection is accepted
while polling for uv events.
Solution: Don't use channel_destroy_early().

Problem: Page scrolling in Insert mode beeps (after 9.1.0211).
Solution: Fix incorrect return value of pagescroll(). Also invert the
return value of scroll_with_sms() to be less confusing and
match comments (zeertzjq).

Problem: windows may scroll horizontally upon resize using the old terminal
size, which may be unnecessary and cause the content to be partially out-of-view.
Solution: reset the horizontal scroll after resizing.

Problem:
Calling os_chdir() to change the child processes' CWD may cause some
unnecessary UI events to be buffered. These UI events don't go anywhere
as execvp() is called before flushing the UI buffer.
Solution:
Use uv_chdir() instead of os_chdir(). Also fix getting error string
incorrectly. Add test for the current behavior.

Problem: Heap UAF if a terminal buffer is deleted during TermRequest in
Normal mode.
Solution: Increment terminal refcount before triggering TermRequest, and
destroy the terminal if the buffer is closed during that.
(cherry picked from commit b40880f88f)
Problem: Cmdline history not updated when mapping both <Up> and <CR>.
Solution: Consider the command typed when in Cmdline mode and there is
no pending input (zeertzjq).
Although the existing behavior technically does match documentation, the
"completely come from mappings" part is a bit ambiguous, because one may
argue that the command doesn't completely come from mappings as long as
the user has typed a key in Cmdline mode. I'm not entirely sure if this
change will cause problems, but it seems unlikely.

When width1 and width2 are negative the assertion may fail. It seems

Problem: nvim_parse_expression null pointer dereference with unmatched ]
followed by a node.
Solution: if ast_stack was empty, set new_top_node_p to top of the stack after
pushing the list literal node; similar to what's done for curlies.
This bug was originally found by a Matrix user, but I couldn't remember how to
trigger it... Ran into the other crash while finding a repro. :P

Problem: nvim_parse_expression null pointer dereference when parsing an
identifier followed by { with "highlight" parameter set to false.
Solution: only set opening_hl_idx if pstate->colors is not NULL.
Not added to parser_tests.lua as that uses highlight = true.
(cherry picked from commit 5226801be2)
Problem: Last buffer not freed with EXITFREE (after 9.1.2087).
Solution: Free the last buffer when inside free_all_mem()
(zeertzjq).
This isn't really a memory leak, as the last buffer's memory is still
reachable via pointers like firstbuf and lastbuf. But it's possible that
this may cause false ASAN warnings in the future, which is what EXITFREE
is supposed to prevent.

Problem: Crash when using :tabonly in BufUnload.

buffer if there are no other buffers. Don't decrement
b_nwindows if it was 0 before buf_freeall() (zeertzjq).

Problem: memory leak when not evaluating (just parsing) invalid literal
dict.
Solution: Always clear the key's typval (Sean Dewar)
Though "check_typval_is_value(&tv) == FAIL && !evaluate" is maybe never
true, also always clear tvs if check_typval_is_value fails; at worst
this would be a no-op as their initial types are VAR_UNKNOWN.

Problem: nvim_get_option_value with "filetype" set can crash if autocommands
open the dummy buffer in more windows, or if &bufhidden == "wipe".
Solution: Attempt to close all dummy buffer windows before wiping. Promote the
dummy buffer to a normal buffer if that fails.
(cherry picked from commit 7e2e116343)
Removed code doesn't seem to do anything? Looks like a clobbered remnant from
when do_filetype_autocmd lived in did_set_string_option.
Doc comment for wipe_buffer doesn't decrement top_file_num since a2d25b7 (2016),
which presumably means the comment on marks doesn't apply either. (fmark_T::fnum
can't refer to the wrong buffer as numbers aren't reused here anymore)
(cherry picked from commit 40114d1631)
Problem: When the "filetype" key is set for nvim_get_option_value, autocommands
can crash Nvim by prematurely wiping the dummy buffer, or cause options intended
for it to instead be set for unrelated buffers if switched during OptionSet.
Solution: Don't crash. Also quash side-effects from setting the buffer options.
(cherry picked from commit 3cb462a960)

Problem: b_locked_split is not checked for :sbuffer, which allows
autocommands to leave windows open to freed buffers.
Solution: In do_buffer_ext, check just before possibly splitting, after
handling 'switchbuf'. Leave win_split to handle the check for
curbuf. (needed even if curbuf is not the target, as setting
the buffer after splitting may fail) (Sean Dewar)

(cherry picked from commit 5f871007d7)
Usually 'langmap' is used to map keyboard characters to ASCII motions or
mappings. It's not entirely clear what the purpose of mapping to Unicode
characters is, but since there is no error for mapping between two chars
both >= 256, only give a warning that this will not work properly when
mapping from a char < 256 to a char >= 256.
(cherry picked from commit 16c1334399)
`%*s` specifies the width limit, not the number of bytes.
In these places it doesn't matter as they are ASCII-only.

Problem: Division by zero in :file after failing to wipe buffer

Solution: Still call buf_clear_file() when failing to wipe buffer
(zeertzjq).

(cherry picked from commit 97bfc0c99b)
Problem: :edit and :enew may reuse a 1-line terminal buffer, causing
the new buffer to still be a terminal buffer.
Solution: Don't reuse a terminal buffer, as it's not reused when it has
more than 1 line.
After this change close_buffer() is the only place where buf_freeall()
can be called on a terminal buffer, so move the buf_close_terminal()
call into buf_freeall() to save some code. Furthermore, closing the
terminal in buf_freeall() is probably more correct anyway, as it is
"things allocated for a buffer that are related to the file".
Also, remove the useless check for on_detach callbacks deleting buffer.
Even if b_locked fails to prevent that, the crash will happen at the end
of buf_updates_unload() first. On the other hand, many other call sites
of buf_updates_unload() and other buffer_updates_* functions don't set
b_locked, which may be a problem as well...

Problem: Crash when deleting terminal buffer and TermClose deletes
other buffers.
Solution: Close the terminal after restoring b_nwindows.
(cherry picked from commit 7297e9d339)
Problem: Calling termopen() or nvim_open_term() on a buffer with an
existing terminal leads to two terminals writing to the same
buffer if the terminal job is still running, or memory leak
if the terminal job has exited.
Solution: Close the terminal if the terminal job has exited, otherwise
report an error.
Problem: Crash when closing a split window if autocmds close other
split windows but there are still floating windows.
Solution: Bail out and give the window back its buffer.
Problem: error set by win_set_buf may leak if autocommands immediately close the
new window.
Solution: free the error set by win_set_buf. (prefer nvim_open_win's error as
it's more important and will cause 0 to be returned)
