Problem:  'cursorlineopt' "screenline" isn't redrawn when moving cursor
          and then using line("w0") and :retab that does nothing.

620c655677 patch 9.1.1831: stray vseps in right-most 'winfixwidth' window
Problem:  vertical separator of 'winfixwidth' windows may remain if they
          become right-most windows from closing windows to the right.
Solution: Don't implicitly rely on frame_new_width to fix vseps, as the
          call may be skipped for 'winfixwidth' windows to preserve
          their width; do it explicitly in winframe_remove (Sean Dewar).

Note that I prefer win_new_width here over setting w_width directly, which
would've previously been done by win_split_ins after frame_add_vsep, as this
wasn't true for winframe_remove.

Though the equivalent issue of bottom 'winfixheight' windows leaving stray
statuslines with &ls=0 doesn't seem to exist, test it anyway.

d839a5b3b0 patch 9.1.1662: Issues with proto files: missing or inconsistent prototypes.
Problem:  Issues with proto files: missing or inconsistent prototypes.
Solution: Update ifdefs, move typedefs, fix prototype declaration
          (Hirohito Higashi)

This change focuses on fixes and tweaks found while working on #18045 for
the proto/*.pro files.

The following fixes and tweaks have been made:

- Fixed a prototype declaration where the variable name differed from
  the function definition.
- Removed a prototype declaration without a function body.
- Fixed a problem where a prototype declaration was not created for a
  function definition enclosed in a #if directive because it lacked ||
  defined(PROTO).
- Moved typedef struct soundcb_S soundcb_T; from proto/sound.pro to
  vim.h.
- Other small tweaks.

The make proto mechanism remains unchanged.

59e1d7f353 patch 9.1.1625: Autocompletion slow with include- and tag-completion
Problem:  Autocompletion slow with include- and tag-completion
Solution: Refactor ins_compl_interrupted() to also check for timeout,
          further refactor code to skip outputting message when
          performing autocompletion (Girish Palya).

Running `vim *` in `vim/src` was slower than expected when
'autocomplete' was enabled. Include-file and tag-file completion
sources were not subject to the timeout check, causing unnecessary
delays.

So apply the timeout check to these sources as well, improving
autocompletion responsiveness, refactor find_pattern_in_path() to take
an additional "silent" argument, to suppress any messages.

b7147f8236 patch 9.1.1084: Unable to persistently ignore events in a window and its buffers
Problem:  Unable to persistently ignore events in a window and its buffers.
Solution: Add 'eventignorewin' option to ignore events in a window and buffer
          (Luuk van Baal)

Add the window-local 'eventignorewin' option that is analogous to
'eventignore', but applies to a certain window and its buffers. Identify
events that should be allowed in 'eventignorewin', adapt "auto_event"
and "event_tab" to encode this information. Window context is not passed
onto apply_autocmds_group(), and when to ignore an event is a bit
ambiguous when "buf" is not "curbuf", rather than a large refactor, only
ignore an event when all windows into "buf" are ignoring the event.

c97e869535 patch 9.1.0993: New 'cmdheight' behavior may be surprising
Problem:  Although patch 9.1.0990 fixed a real problem/inconsistency,
          it also introduced new behavior that may break BWC and/or be
          unexpected. Before 9.1.0990, window commands could make the
          topframe smaller (without changing 'cmdheight'; quirk that is
          now fixed), but did not allow extending the topframe beyond
          the 'cmdheight' set by the user. After 9.1.0990, the user can
          reduce the 'cmdheight' below the value they set explicitly,
          through window commands, which may lead to confusion.
          (aftere v9.1.0990)
Solution: Store the value explicitly set by the user and clamp the
          'cmdheight' when resizing the topframe. This also applies to
          dragging laststatus, which in contrast to window commands
          _did_ allow reducing the 'cmdheight' to values below the one
          set by the user. So with this patch there is still new
          behavior, but I think in a way that is less surprising.
          While at it, also fix a Coverity warning, introduced in
          v9.1.0990 (Luuk van Baal)

2cddf0e85a patch 9.1.0892: the max value of 'tabheight' is limited by other tabpages
Problem:  the max value of 'tabheight' is limited by other tabpages
Solution: Limit the maximum value of 'cmdheight' to the current tabpage only.
          (Milly)

The Help says that cmdheight is local to the tab page, but says nothing
about the maximum value depending on the state of all tab pages. Users
may wonder why they can't increase cmdheight when there are still rows
available on the current tab page. This PR changes the behavior of
cmdheight so that its maximum value depends only on the state of the
current tab page.

Also, since magic numbers were embedded in various places with the
minimum value of cmdheight being 1, we defined a constant to make it
easier to understand.

          which prevents a use-after-free by setting those pointers

eb80b8304e patch 9.1.0374: wrong botline in BufEnter
Problem:  When :edit an existing buffer, line('w$') may return a
          wrong result.
Solution: Reset w_valid in curwin_init() (Jaehwang Jung)

`do_ecmd()` reinitializes the current window (`curwin_init()`) whose
`w_valid` field may have `VALID_BOTLINE` set. Resetting `w_botline`
without marking it as invalid makes subsequent `validate_botline()`
calls a no-op, thus resulting in wrong `line('w$')` value.

5866bc3a0f patch 9.1.0175: wrong window positions with 'winfix{width,height}'
Problem:  winframe functions incorrectly recompute window positions if
          the altframe wasn't adjacent to the closed frame, which is
          possible if adjacent windows had 'winfix{width,height}' set.

Solution: recompute for windows within the parent of the altframe and
          closed frame. Skip this (as before) if the altframe was
          top/left, but only if adjacent to the closed frame, as
          positions won't change in that case. Also correct the return
          value documentation for win_screenpos. (Sean Dewar)

The issue revealed itself after removing the win_comp_pos call below
winframe_restore in win_splitmove. Similarly, wrong positions could result from
windows closed in other tabpages, as win_free_mem uses winframe_remove (at least
until it is entered later, where enter_tabpage calls win_comp_pos).

NOTE: As win_comp_pos handles only curtab, it's possible via other means for
positions in non-current tabpages to be wrong (e.g: after changing 'laststatus',
'showtabline', etc.). Given enter_tabpage recomputes it, maybe it's intentional
as an optimization? Should probably be documented in win_screenpos then, but I
won't address that here.

5cac1a9bee patch 9.1.0171: Small split-move related improvements
Problem:  small improvements can be made to split-move related
          functions.
Solution: apply them (Sean Dewar):

- Improve some doc comments (frame_flatten should still work for non-current
  tabpages, despite the topframe check, which looks benign, though I'm unsure if
  it's still needed; see #2467).

- f_win_splitmove should check_split_disallowed on wp, not targetwin, as that's
  what win_splitmove checks (though it's probably unnecessary to check
  b_locked_split at all; see #14109, which I hope to get around to finishing at
  some point).

- Make winframe_restore restore window positions for the altframe, which
  winframe_remove changes. This doesn't affect the prior behaviour, as we called
  win_comp_pos after, but as win_comp_pos only works for curtab, and
  winframe_remove supports non-current tabpages, we should undo it. Regardless,
  this should mean we don't need win_comp_pos anymore; adjust tests to check
  that window positions remain unchanged.

  I'm not sure win_comp_pos is needed after last_status anyway if it doesn't
  steal rows from another frame to make room for a new statusline, which
  shouldn't be the case after winframe_remove? To be safe, I'll leave it as is.

d64801e913 patch 9.1.0170: Re-allow curwin == prevwin, but document it instead
Problem:  more places exist where curwin == prevwin, and it may even be
          expected in some cases.
Solution: revert v9.1.0001, but document that it's possible instead.
          (Sean Dewar)

I've had a change of heart for the following reasons:

- A quick 'n dirty [GitHub code
  search](https://github.com/search?q=%2F%28winnr%5C%28%5C%29%5Cs*%3D%3D%5Cs*winnr%5C%28%5B%27%22%5D%23%5B%27%22%5D%5C%29%7Cwinnr%5C%28%5B%27%22%5D%23%5B%27%22%5D%5C%29%5Cs*%3D%3D%5Cs*winnr%5C%28%5C%29%29%2F&type=code)
  reveals some cases where it's expected in the wild.

  Particularly, it made me aware `winnr() == winnr('#')` is possible when curwin
  is changed temporarily during the evaluation of a &statusline expression item
  (`%{...}`), and is used to show something different on the statusline
  belonging to the previous window; that behaviour wasn't changed in v9.1.0001,
  but it means curwin == prevwin makes sense in some cases.

- The definition and call sites of back_to_prevwin imply some expectation that
  prevwin == wp (== curwin) is possible, as it's used to skip entering the
  prevwin in that case.

- Prior to v9.1.0001, `:wincmd p` would not beep in the case that was patched in
  v9.1.0001, but now does. That resulted in #14047 being opened, as it affected
  the CtrlP plugin.

  I find it odd that `:wincmd p` had cases where it wouldn't beep despite doing
  nothing, but it may be preferable to keep things that way (or instead also
  beep if curwin == prevwin, if that's preferred).

- After more digging, I found cases in win_free_mem, enter_tabpage,
  aucmd_restbuf and qf_open_new_cwindow where curwin == prevwin is possible
  (many of them from autocommands). Others probably exist too, especially in
  places where curwin is changed temporarily.

b2ec0da080 patch 9.1.0159: Crash in WinClosed after BufUnload closes other windows
Problem:  Crash in WinClosed after BufUnload closes other windows
Solution: Don't trigger WinClosed if the buffer is NULL (zeertzjq)

Now win_close_othertab() doesn't trigger any autocommands if the buffer
is NULL, so remove the autocmd blocking above (which was added not long
ago in patch v9.0.0550) for consistency.

Also remove an unreachable close_last_window_tabpage() above:
- It is only reached if only_one_window() returns TRUE and last_window()
  returns FALSE.
- If only_one_window() returns TRUE, there is only one tabpage.
- If there is only one tabpage and last_window() returns FALSE, the
  one_window() in last_window() must return FALSE, and the ONE_WINDOW
  in close_last_window_tabpage() must also be FALSE.
- So close_last_window_tabpage() doesn't do anything and returns FALSE.

Then the curtab != prev_curtab check also doesn't make much sense, and
the only_one_window() can be replaced with a check for popup and a call
to last_window() since this is a stricter check than only_one_window().

4bb505e28c patch 9.1.0150: Several minor 'winfixbuf' issues
Problem:  several minor 'winfixbuf' issues exist, mostly relating to the
          quickfix list
Solution: address them and adjust tests. Retab and reflow a few things too.
          (Sean Dewar)

Things touched include:

- Replace the semsgs with gettext'd emsgs.

- Handle window switching in ex_listdo properly, so curbuf and curwin
  are kept in-sync and trigger autocommands; handle those properly.

- Don't change the list entry index in qf_jump_edit_buffer if we fail
  due to 'wfb' (achieved by returning FAIL; QF_ABORT should only be used
  if the list was changed).

- Make qf_jump_edit_buffer actually switch to prevwin when using `:cXX`
  commands **outside** of the list window if 'wfb' is set in curwin.
  Handle autocommands properly in case they mess with the list.

  NOTE: previously, it seemed to split if 'wfb' was set, but do nothing
  and fail if prevwin is *valid*. This behaviour seemed strange, and maybe
  unintentional? Now it aligns more with what's described for the `:cXX`
  commands in the original PR description when used outside a list window,
  I think.

- In both functions, only consider prevwin if 'wfb' isn't set for it;
  fallback to splitting otherwise.

- Use win_split to split. Not sure if there was a specific reason for
  using ex_splitview. win_split is simpler and respects modifiers like
  :vertical that may have been used. Plus, its return value can be checked
  for setting opened_window in qf code (technically win_split_ins autocmds
  could immediately close it or change windows, in which the qf code might
  close some other window on failure; it's already the case elsewhere,
  though).

55f8bba73b patch 9.1.0143: [security]: autocmd causes use-after-free in set_curbuf()
Problem:  [security]: autocmd cause use-after-free in set_curbuf()
          (kawarimidoll)
Solution: check side-effect of BufLeave autocommand, when the number
          of windows changed, close windows containing buffers that will
          be wiped, if curbuf changed unexpectedly make sure b_nwindows
          is decremented otherwise it cannot be wiped

set_curbuf() already makes some efforts to ensure the BufLeave
autocommands do not cause issues.  However there are still 2 issues
that are not taken care of:

1) If a BufLeave autocommand opens a new window containing the same
buffer as that is going got be closed in close_buffer() a bit later,
we suddenly have another window open, containing a free'd buffer.  So we
must check if the number of windows changed and if it does (and the
current buffer is going to be wiped (according to the 'bufhidden'
setting), let's immediately close all windows containing the current
buffer using close_windows()

2) If a BufLeave autocommand changes our current buffer (displays it in
the current window), buf->b_nwindow will be incremented. As part of
set_curbuf() we will however enter another buffer soon, which means, the
newly created curbuf will have b_nwindows still have set, even so the
buffer is no longer displayed in a window. This causes later problems,
because it will no longer be possible to wipe such a buffer. So just
before entering the final buffer, check if the curbuf changed when
calling the BufLeave autocommand and if it does (and curbuf is still
valid), decrement curbuf->b_nwindows.

Both issues can be verified using the provided test (however the second
issue only because such an impacted buffer won't be wiped, causing
futher issues in later tests).

02fcae02a9 patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll'
Problem:  infinite loop in win_update with 'smoothscroll' set when
          window width is equal to textoff, or signed integer overflow
          if smaller.
Solution: don't revalidate wp->w_skipcol in that case, as no buffer text
          is being shown. (Sean Dewar)

Don't instead reset w_skipcol; that would lose the scroll position
within the line, which may be undesirable if the window is made wider
later.

Also include changes from the splitmove PR #14042 that I (in my infinite
Git wisdom) forgot to commit. This includes a change to
Test_window_split_no_room to ensure it doesn't fail for some screen
sizes.

Move Test_smoothscroll_in_zero_width_window to test_scroll_opt.vim, as
that file feels more appropriate.
