09d4133 changed blocknr_T from long to int64_t, so pe_bnum is now always 64-bit. This was an incompatible change in the swapfile format for 32-bit systems, but there have been no complaints in the past 9 years so just adjust the test.
Problem: Unused assignments when checking the value of 'listchars'.
Solution: Loop only once when just checking the value. Add a test to
check that this change doesn't cause double-free.

Problem: File info disappears immediately when 'cmdheight' has just
decreased due to switching tabpage and 'shortmess' doesn't
contain 'o' or 'O'.
Solution: Make sure msg_row isn't smaller than cmdline_row.

skipwhite was iterating over the input twice and scanning for the null
byte character with strlen. this is redundant, because it's already
covered by ascii_iswhite that accepts only space or tab character.

runtime(netrw): Fix handling of very long filename on longlist style (vim/vim#12150)
If there is a file with a very long filename (longer than
g:netrw_maxfilenamelen), and if g:netrw_liststyle is set to 1, no space
is inserted between the filename and the filesize and the file cannot be
opened because of this.
E.g.:
```
$ echo hello > 12345678901234567890123456789012 # 32 bytes: OK
$ echo hello > 123456789012345678901234567890123 # 33 bytes: not OK
$ echo hello > 1234567890123456789012345678901234 # 34 bytes: not OK
$ echo hello > こんにちは # multibyte filename
$ LC_ALL=C.UTF-8 vim . --clean --cmd "set loadplugins" --cmd "let g:netrw_liststyle=1"
```
Then, it will be shown like this:
```

If the length of the filename is 32 bytes, there is a space between the
filename and the filesize. However, when it is longer than 32 bytes, no
space is shown.
Also, you may find that the filesize of the multibyte named file is not
aligned.
After this patch is applied, the filelist will be shown like this:

Now we have 32 + 2 + 15 = 49 characters for filename and filesize.
It tries to align the filesize as much as possible.
The last line that has multibyte filename is also aligned.
Also fixed the issue that the file list is not shown correctly when
g:netrw_sort_by is set to 'size' and g:netrw_sizestyle is set to 'h' or
'H'.

Problem: [security]: use-after-free in ex_substitute
Solution: always allocate memory
closes: vim/vim#13552
A recursive :substitute command could cause a heap-use-after free in Vim
(CVE-2023-48706).
The whole reproducible test is a bit tricky, I can only reproduce this
reliably when no previous substitution command has been used yet
(which is the reason, the test needs to run as first one in the
test_substitute.vim file) and as a combination of the `:~` command
together with a :s command that contains the special substitution atom `~\=`
which will make use of a sub-replace special atom and calls a vim script
function.
There was a comment in the existing :s code, that already makes the
`sub` variable allocate memory so that a recursive :s call won't be able
to cause any issues here, so this was known as a potential problem
already. But for the current test-case that one does not work, because
the substitution does not start with `\=` but with `~\=` (and since
there does not yet exist a previous substitution atom, Vim will simply
increment the `sub` pointer (which then was not allocated dynamically)
and later one happily use a sub-replace special expression (which could
then free the `sub` var).
The following commit fixes this, by making the sub var always using
allocated memory, which also means we need to free the pointer whenever
we leave the function. Since sub is now always an allocated variable,
we also do no longer need the sub_copy variable anymore, since this one
was used to indicated when sub pointed to allocated memory (and had
therefore to be freed on exit) and when not.

The most general conditions should come before more specific conditions.
For example, `UNIX` options needs to be specified before any
distro-specific options. This way distro specific options takes priority
over the general case in case there's a conflict.
Problem: Unable to identify legacy signs when fetching extmarks with
`nvim_buf_get_extmarks()`.
Solution: Add "sign_name" to the extmark detail array.
Add some misc. changes as follow-up to #25724
Remove the monolithic Decoration struct. Before this change, each extmark
could either represent just a hl_id + priority value as a inline
decoration, or it would take a pointer to this monolitic 112 byte struct
which has to be allocated.
This change separates the decorations into two pieces: DecorSignHighlight
for signs, highlights and simple set-flag decorations (like spell,
ui-watched), and DecorVirtText for virtual text and lines.
The main separation here is whether they are expected to allocate more
memory. Currently this is not really true as sign text has to be an
allocated string, but the plan is to get rid of this eventually (it can
just be an array of two schar_T:s). Further refactors are expected to
improve the representation of each decoration kind individually. The
goal of this particular PR is to get things started by cutting the
Gordian knot which was the monolithic struct Decoration.
Now, each extmark can either contain chained indicies/pointers to
these kinds of objects, or it can fit a subset of DecorSignHighlight
inline.
The point of this change is not only to make decorations smaller in
memory. In fact, the main motivation is to later allow them to grow
_larger_, but on a dynamic, on demand fashion. As a simple example, it
would be possible to augment highlights to take a list of multiple
`hl_group`:s, which then would trivially map to a chain of multiple
DecorSignHighlight entries.
One small feature improvement included with this refactor itself, is
that the restriction that extmarks cannot be removed inside a decoration
provider has been lifted. These are instead safely lifetime extended
on a "to free" list until the current iteration of screen drawing is done.
NB: flags is a mess. but DecorLevel is useless, this slightly less so
Problem: [security] use-after-free in qf_free_items
Solution: only access qfpnext, if it hasn't been freed
Coverity discovered a possible use-after-free in qf_free_items. When
freeing the qfline items, we may access freed memory, when qfp ==
qfpnext.
So only access qfpnext, when it hasn't been freed.

Enable all clang-tidy warnings by default instead of disabling them.
This ensures that we don't miss useful warnings on each clang-tidy
version upgrade. A drawback of this is that it will force us to either
fix or adjust the warnings as soon as possible.
Quick fix as follow up to https://github.com/neovim/neovim/pull/26108
kqueue only reports events on a watched folder itself, not for files
created or deleted within. So the approach the PR took doesn't work on FreeBSD.
We'll either need to bring back polling for it, combine watching with manual
file tracking, or disable LSP file watching on FreeBSD
Should help with https://github.com/neovim/neovim/issues/23291
On linux `new_fs_event` doesn't support recursive watching, but we can
still use it to watch folders.
The downside of this approach is that we may end up sending some false
`Deleted` events. For example, if you save a file named `foo` there will
be a intermediate `foo~` due to the save mechanism of neovim.
The events we get from vim.uv in that case are:
- rename: foo~
- rename: foo~
- rename: foo
- rename: foo
- change: foo
- change: foo
The mechanism in this PR uses a debounce to reduce this to:
- deleted: foo~
- changed: foo
`foo~` will be the false positive.
I suspect that for the LSP case this is good enough. If not, we may need
to follow up on this and keep a table in memory that tracks available
files.
