If `use_rgb` was false, we would attempt to set the `cterm_bg_color` to the
variable `bg`, which is only retrieved from `bg` and `background` keys, not
`ctermbg`. Same for `fg`. This means the values would be `-1` (the default,
un-got value) and we'd always set the returned values to `0`.
My understanding is `fg/bg` is always "gui" values, so instead we should be
using `ctermbg` when needed.
Nb: when looking around I think this function is currently *always* called with
`use_rgb = true`.
Fixes#18980
- 831fa45ad8 is related but this doesn't regress that
- The `cterm_normal_fg_color != ae.cterm_fg_color` comparison is originally
carried from patch to patch starting all the way back in 29bc6dfabd where it
was avoiding setting a HL attr. But `hlattrs2dict()` now is just
informational.
The current emulation script enters Insert mode much too frequently.
Using only BufWinEnter seems to be a closer simulation.
Also add a few more mappings.
Steps to reproduce:
1. setting `vim.highlight.on_yank`
```
vim.api.nvim_create_autocmd({ "TextYankPost" }, {
pattern = { "*" },
callback = function()
vim.highlight.on_yank({ timeout = 200 })
end,
})
```
2. repeat typing `yeye` ...
3. causes the following error.
```

Problem:
- Unix sockets are created in random /tmp dirs.
- /tmp is messy, unclear when OSes actually clear it.
- The generated paths are very ugly. This adds friction to reasoning
about which paths belong to which Nvim instances.
- No way to provide a human-friendly way to identify Nvim instances in
logs or server addresses.
Solution:
- Store unix sockets in stdpath('state')
- Allow --listen "name" and serverstart("name") to given a name (which
is appended to a generated path).
TODO:
- is stdpath(state) the right place?
Problem:
1. Log messages (especially in CI) are hard to correlate with tests.
2. Since b353a5c05f#11886, dumplog() prints the logs next to test
failures. This is noisy and gets in the way of the test results.
Solution:
1. Associate an incrementing id with each test and include it in log
messages.
- FUTURE: add v:name so Nvim instances can be formally "named"?
2. Mention "child" in log messages if the current Nvim is a child (based
on the presence of $NVIM).

Problem: Value of cmod_verbose is a bit complicated to use.
Solution: Use zero for not set, value + 1 when set. (closesvim/vim#10564)

Omit has_cmdmod(): only used for Vim9 script
Problem: Command modifiers are saved and set inconsistently.
Solution: Separate parsing and applying command modifiers. Save values in
cmdmod_T.

Cherry-pick: :0verbose fix from patch 8.2.4741
drawback: tracing memory errors with ASAN is less accurate for arena
allocated memory.
Therefore, to start with it is being used for Object types around
serialization/deserialization exclusively. This is going to have
a large impact especially when TUI is refactored as a co-prosess
as all UI events will be serialized and deserialized by nvim itself.
Problem: Not all modifiers supported for :options.
Solution: Use all cmdmod.split flags. (closesvim/vim#4401)

Problem: DirChanged autocommand may use freed memory. (Shane-XB Qian)
Solution: Free the memory later. (closesvim/vim#10555)

Code change is N/A as Nvim gets the full current directory again before
applying the autocommand, so this just ports the tests.
Problem:
Since 6d57bb89c1#18543, luacheck is not found on some systems when
running the "lintlua" target.
Solution:
- Move the find_program() to the top-level CMakeLists.txt
- Define a def_cmd_target() function with fewer assumptions than the old
lint() function.
- Move "lintuncrustify" to src/nvim/CMakeLists.txt so it can reuse the
$LINT_NVIM_SOURCES already defined there.
- Make the lint targets _fatal_ by default. There is little reason for
the "lint" umbrella target defined in Makefile to exist if it's going
to ignore the absence of the actual linters.
- For now, keep the uncrustify call in a separate cmake script so that
it can be silenced (too noisy).
There can be other places that access window buffer info (e.g.
`tabpagebuflist()`), so checking `w_closing` in `win_findbuf()` doesn't
solve the crash in all cases, and may also cause Nvim's behavior to
diverge from Vim.
Fix#14998
