fix(api): auto-load buffers in nvim_buf_set_* operations
Problem: Setting marks, lines, or text on unloaded buffers fails because
ml_line_count is not accurate until the buffer is loaded.
Solution: Add require_loaded_buffer() helper and use it in write operations
(nvim_buf_set_lines, nvim_buf_set_text, nvim_buf_set_mark). These now
auto-load buffers as needed.
Problem: has("terminfo") test fails on local runs because it expects
"HAVE_UNIBILIUM " in the :version info to mean that nvim was built
without unibilium.
Solution: Assume nvim is built with unibilium if HAVE_UNIBILIUM is
present in the version string and is NOT followed by 0, false, or off.
This isn't affecting CI runs because when the test detects that it is
running in CI it doesn't use the :version string at all.

* test(core/channels_spec): fix flaky test
Always use expect_stdout() to check PTY output.
* test(autocmd/termxx_spec): fix flaky test
Usually the Ctrl-C cancels the following :qa!, but sometimes it doesn't,
and Nvim exits before feed() returns. Instead make sure that :qa! always
reaches Nvim and use expect_exit().
Problem:
Crashed Nvim leaves socket files. Subsequent starts fail with "address already in use".
Solution:
On bind failure, test socket liveness via connect(). Remove if stale, retry bind().
Fixes#36581
Problem:
With shadow border, scrollbar and border overlap. Shadow's right border
starts from the second row (offset by 1), but scrollbar renders on every
row including the first. If they share a column, the first row shows
scrollbar where shadow hasn't started yet, causing misalignment.
Solution:
Separate scrollbar from the shadow's right border.
Problem: Crash with 'wildmenu' when typing Ctrl-Y after Ctrl-A
(after 9.1.1714) (fizz-is-on-the-way).
Solution: Check if there are matches before applying one (zeertzjq).

Problem: :wqall! doesn't quit when using :quit in BufWritePost
(after 8.0.1190).
Solution: Restore old value of "exiting" when calling not_exiting()
instead of always resetting it to FALSE (zeertzjq).

Problem: TabClosedPre may be triggered twice for the same tab page when
closing another tab page in BufWinLeave (after 9.1.1211).
Solution: Store whether TabClosedPre was triggered in tabpage_T
(zeertzjq).
Also fix the inconsistency that :tabclose! triggers TabClosedPre after
a failed :tabclose, but :close! doesn't even if there is only one window
in the tab page.

Problem: heap-use-after-free when wiping buffer in TabClosedPre.
Solution: Check window_layout_locked() when closing window(s) in another
tabpage (zeertzjq).

Problem: tests: not checking error numbers properly.
Solution: Add a trailing comma to avoid matching a different error
number with the same prefix (zeertzjq)
closes: vim/vim#1715967fe77d272
Problem: TabClosedPre is triggered just before the tab is being freed,
which limited its functionality.
Solution: Trigger it a bit earlier and also on :tabclose and :tabonly

Problem: Some plugins have a problem with the error check for using

Problem: A message ending in an unprintable character may emit a
msg_show event with the "empty" kind. No empty message event
for echom "".
Solution: Adjust conditions for emitting "empty" msg_show events.
Problem:
Creating an autocommand which executes `:bwipe` on the Syntax event
causes a heap-use-after-free.
Solution: set BF_SYN_SET flag before applying autocommands
Problem:
When text is too long, it overflows into the border. This happens because
grid_line_maxcol includes border columns, so grid_line_puts can write
there.
Solution:
Truncate string to available width when need_fcs_trunc is set.
When width1 and width2 are negative the assertion may fail. It seems
that adding a negative value to w_curswant won't cause any problems, so
just change the assertion.
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.
Problem: Crash when using :tabonly in BufUnload.
Solution: Set curbuf when setting curwin->w_buffer. Don't wipe out a
buffer if there are no other buffers. Don't decrement
b_nwindows if it was 0 before buf_freeall() (zeertzjq).

Thinking about this again, it's actually OK to check split_disallowed in
window_layout_locked(), so add the check.
Also add missing window_layout_locked() in tabpage_close().

Problem: Redundant NULL checks in find_pattern_in_path().
Solution: Remove the NULL checks. Also fix typos in test_diffmode.vim
(zeertzjq).
After assigning to inc_opt on line 2976, it's dereferenced immediately,
and not assigned another value afterwards, so checking for NULL after
line 2977 is redundant.

Problem: Vim tests are slow and flaky at the same time due to reliance

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.
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.

Problem:
`t.skip()` adds to the "pending" list. If there is no path to fixing
a pending test, it adds noise to the pending list.
Solution:
Return early instead of using `t.skip()`.
