When `root_dir` is a function it can (and often will) call the provided
callback function in a fast API context (e.g. in the `on_exit` handler
of `vim.system`). When the callback function is executed we should
ensure that it runs vim.lsp.start on the main event loop.
Problem: Anchoring a floating window to the tabline and laststatus is
cumbersome; requiring autocommands and looping over all
windows/tabpages.
Solution: Add new "tabline" and "laststatus" options to the `relative`
field of nvim_open_win() to place a window relative to.
**Problem:** The treesitter `foldexpr` runs synchronous parses to
calculate fold levels, which eliminates async parsing performance in the
highlighter.
**Solution:** Migrate the `foldexpr` to also calculate and apply fold
levels asynchronously.
Problem:
The floating window for hover and signature help always cuts off a few lines,
because the `_make_floating_popup_size` function counts empty lines as having
zero height.
Solution:
Ensure the height is at least 1.
Problem:
Whether an option is allowed to be empty isn't well defined and
isn't properly checked.
Solution:
- For non-list string options, explicitly check the option value
if it is empty.
- Annotate non-list string options that can accept an empty value.
- Adjust command completion to ignore the empty value.
- Render values in Lua meta files
**Problem:** `vim.treesitter.get_parser()` and `vim.treesitter.start()`
both parse the tree before returning it. This is problematic because if
this is a sync parse, it will stall the editor on large files. If it is
an async parse, the functions return stale trees.
**Solution:** Remove this parsing side effect and leave it to the user
to parse the returned trees, either synchronously or asynchronously.
**Problem:** Parsing can be slow for large files, and it is a blocking
operation which can be disruptive and annoying.
**Solution:** Provide a function for asynchronous parsing, which accepts
a callback to be run after parsing completes.

**Problem:** Query parsing uses a weak cache which is invalidated
frequently
**Solution:** Make the cache strong, and invalidate it manually when
necessary (that is, when `rtp` is changed or `query.set()` is called)

Problem: filetype: various ignore are not recognized
Solution: detect rg/docker/npm/vvsce ignore files as 'gitgnore' filetype
(Wu, Zhenyu)
Not only prettier, but many programs also support ignore files (like rg,
docker, npm, vscode). So use the gitignore filetype for them due to same syntax

BREAKING CHANGE: This changes the list of diagnostics that are passed to
a diagnostic handler. If a handler is already filtering by severity
itself then this won't break anything, since the handler's filtering
will become a no-op. But handlers which depend on receiving the full
list of diagnostics may break.
Note that diagnostics are only filtered if the handler's configuration
has the `severity` option set. If `severity` is not set, the handler
still receives the full list of diagnostics.
Problem:
The `nvim_notify` API (note: unrelated to `vim.notify()` Lua API) was
not given any real motivation in https://github.com/neovim/neovim/pull/13843
There are, and were, idiomatic and ergonomic alternatives already.
Solution:
Deprecate `nvim_notify`.
Problem: We want to deprecate `nvim_err_write(ln)()` but there is no
obvious replacement (from Lua). Meanwhile we already have
`nvim_echo()` with an `opts` argument.
Solution: Add `err` argument to `nvim_echo()` that directly maps to
`:echoerr`.
Problem: incorrect return type doc causes luals `Annotations specify that at most 0 return value(s) are required, found 1 returned here instead.` diagnosis
Solution: correct return type doc
**Problem:** The treesitter `foldexpr` calls `get_parser()` for each
line in the buffer when calculating folds. This can be incredibly slow
for buffers where a parser cannot be found (because the result is not
cached), and exponentially more so when the user has many
`runtimepath`s.
**Solution:** Only fetch the parser when it is needed; that is, only
when initializing fold data for a buffer.

Problem: open_floating_preview() may be hidden behind current window if
that is floating and has a higher zindex.
Solution: Open floating preview with zindex higher than current window.
Problem: Prompts are emitted as messages events, where cmdline events
are more appropriate. The user input is also emitted as
message events in fast context, so cannot be displayed with
vim.ui_attach().
Solution: Prompt for user input through cmdline prompts.
* Cancel watcher in the "force" case.
* Cancel watcher outside the async callback. It seems nvim doesn't wait
async jobs on quitting, leaving detached inotifywait processes.
* Clean up cancelling callbacks.
Allows to retrieve the configuration as it will be used by `lsp.enable`
- including the parts merged from `*` and rtp.
This is useful for explicit startup control
(`vim.lsp.start(vim.lsp.config[name])`)
