Problem: possible crash when calculating topline in diff.c

Solution: Check for pointer being Null before accessing it

The POC is likely not applicable to Nvim due to #32160.

Problem: Vim tests are slow and flaky at the same time due to reliance
on timeouts which are unreliable.
Solution: improve Vim test performance and reduce flakiness
(Yee Cheng Chin)
A lot of Vim tests currently rely on waiting a specific amount of time
before asserting a condition. This is bad because 1) it is slow, as the
timeout is hardcoded, 2) it's unreliable as a resource-starved runner
may overshoot the timeout. Also, there are a lot of builtin sleep
commands in commonly used utilities like VerifyScreenDump and WaitFor()
which leads to a lot of unnecessary idle time.
Fix these issues by doing the following:
1. Make utilities like VerifyScreenDump and WaitFor use the lowest wait
time possible (1 ms). This essentially turns it into a spin wait. On
fast machines, these will finish very quickly. For existing tests
that had an implicit reliance on the old timeouts (e.g.
VerifyScreenDump had a 50ms wait before), fix the tests to wait that
specific amount explicitly.
2. Fix tests that sleep or wait for long amounts of time to instead
explicitly use a callback mechanism to be notified when a child
terminal job has finished. This allows the test to only take as much
time as possible instead of having to hard code an unreliable
timeout.
With these fixes, tests should 1) completely quickly on fast machines,
and 2) on slow machines they will still run to completion albeit slowly.
Note that previoulsy both were not true. The hardcoded timeouts meant
that on fast machines the tests were mostly idling wasting time, whereas
on slow machines, the timeouts often were not generous enough to allow
them to run to completion.

Part of shared.vim and test_crash.vim changes only.

**Problem(?):** Buffers that (for whatever reason) aren't meant to have
a final newline are still parsed with a final newline in `treesitter.c`.
**Solution:** Don't add the newline to the last buffer line if it
shouldn't be there. (This more closely matches the approach of
`read_buffer_into()`.)
This allows us to, say, use a scratch buffer with `noeol` and `nofixeol`
behind the scenes in `get_string_parser()`.
...which would allow us to track injection trees with extmarks in that
case.
...which would allow us to not drop previous trees after reparsing a
different range with `get_parser():parse()`.
...which would prevent flickering when editing a buffer that has 2+
windows to it in view at a time.
...which would allow us to keep our sanity!!!
(one step at a time...)

Problem: Marks are lost after `:bdelete` because `ignore_buf()` filters
out unlisted buffers during shada mark processing.
Solution: Revert to original buffer checks for mark operations, avoiding
`!buf->b_p_bl` condition that incorrectly ignores deleted buffers.
Problem: completion: "longest" doesn't work for manual completion when
'autocomplete' is on (after 9.1.1800).

Problem: completion: autocompletion can be improved
Solution: Add support for "longest" and "preinsert" in 'autocomplete';
add preinserted() (Girish Palya)
* Add support for "longest" in 'completeopt' when 'autocomplete'
is enabled. (Note: the cursor position does not change automatically
when 'autocomplete' is enabled.)
* Add support for "preinsert" when 'autocomplete' is enabled. Ensure
"preinsert" works the same with and without 'autocomplete'
* introduce the preinserted() Vim script function, useful for defining
custom key mappings.

Problem: Option insecure flags not copied when splitting window.
Solution: Move window-local insecure flags to winopt_T and copy them
properly (zeertzjq).
closes: vim/vim#18434b3740f4b00
Problem: :set doesn't clear local insecure flag like :setlocal does.
Solution: Also clear the local insecure flag when using :set (zeertzjq).
This applies to local options like 'wrap', 'foldtext' and 'foldexpr',
whose global flags are actually never used. For global-local options
like 'statusline' the behavior is already correct, so add some tests.

Problem: 'nowrap' in a modeline may hide malicious code.
Solution: Forcibly use '>' as 'listchars' "extends" if 'nowrap' was set
from a modeline (zeertzjq).
Manual `:setlocal nowrap` disables this behavior. There is a separate
problem with `:set nowrap` that also applies to some other options.

Cherry-pick some test_modeline.vim changes from patches 9.0.{0363,0626}.
Problem: :update should write new file buffers, but previous fix
affected special buffer types (acwrite, nofile, etc.).
Solution: Add bt_nofilename() check to only write new files for
buffers representing real filesystem paths.
Problem: update command does not write new buffers that have
filenames but no corresponding file on disk, even when using ++p flag.
Solution: allow update to write when buffer has filename but file
doesn't exist.
Problem: Wrong display with 'smoothscroll' and long wrapped virtual
text at EOL.
Solution: Handle w_skipcol inside long wrapped virtual text at EOL

- Remove "state" directory after each test, so that a failure in one

Problem: filetype: not all Sway config files are recognized
Solution: Detect files within */sway/config.d/* as swayconfig filetype
(Felix Pehla).
Sways default config automatically includes files placed in
@sysconfdir@/sway/config.d/* (see config.in), so it makes sense to use
the sway syntax for those.

Use only a single clear() call in some test/functional/vimscript/ test
files whose test cases have very little side effect.
A downside of using a single clear() is that if a crash happens in one
test case, all following test cases in the same file will also fail, but
these functionalities and tests don't change very often.

Problem: complete: some redraw issues with 'autocomplete'
Solution: Fix the issues (Girish Palya)
This commit contains the following changes:
* Fix that wildtrigger() might leave opened popupmenu around vim/vim#18298
* Remove blinking message on the command line when a menu item from a loaded
buffer is selected during 'autocomplete'
* Add a test for PR vim/vim#18265 to demonstrate why the PR is required for correct
'autocomplete' behavior

Problem: When the popup menu (PUM) occupies more than half the screen
height, it flickers whenever a character is typed or erased.
This happens because the PUM is cleared and the screen is
redrawn before a new PUM is rendered. The extra redraw between
menu updates causes visible flicker.
Solution: A complete, non-hacky fix would require removing the
CmdlineChanged event from the loop and letting autocompletion
manage the process end-to-end. This is because screen redraws
after any cmdline change are necessary for other features to
work.
This change modifies wildtrigger() so that the next typed
character defers the screen update instead of redrawing
immediately. This removes the intermediate redraw, eliminating
flicker and making cmdline autocompletion feel smooth
(Girish Palya).
Trade-offs:
This behavior change in wildtrigger() is tailored specifically for
:h cmdline-autocompletion. wildtrigger() now has no general-purpose use
outside this scenario.
