Problem:
The documentation flow (`gen_vimdoc.py`) has several issues:
- it's not very versatile
- depends on doxygen
- doesn't work well with Lua code as it requires an awkward filter script to convert it into pseudo-C.
- The intermediate XML files and filters makes it too much like a rube goldberg machine.
Solution:
Re-implement the flow using Lua, LPEG and treesitter.
- `gen_vimdoc.py` is now replaced with `gen_vimdoc.lua` and replicates a portion of the logic.
- `lua2dox.lua` is gone!
- No more XML files.
- Doxygen is now longer used and instead we now use:
- LPEG for comment parsing (see `scripts/luacats_grammar.lua` and `scripts/cdoc_grammar.lua`).
- LPEG for C parsing (see `scripts/cdoc_parser.lua`)
- Lua patterns for Lua parsing (see `scripts/luacats_parser.lua`).
- Treesitter for Markdown parsing (see `scripts/text_utils.lua`).
- The generated `runtime/doc/*.mpack` files have been removed.
- `scripts/gen_eval_files.lua` now instead uses `scripts/cdoc_parser.lua` directly.
- Text wrapping is implemented in `scripts/text_utils.lua` and appears to produce more consistent results (the main contributer to the diff of this change).

Problem: Any preceding luadocs block that define alias types with
`@alias` magic would be prepended to the documentation of functions
that follow, despite the "blank line" separator. For example:
```
--- @alias some.type.between.functions
--- Blah blah long documentation for alias
--- | "foo" # foo
--- | "bar" # bar
--- The documentation that should appear in vimdoc.
function M.function_to_include_in_doc()
...
end
```
then the vimdoc generated for `function_to_include_in_doc` would include
the text from the alias block (e.g., "Blah blah ... for alias").
Solution:
- refactor: Lua2DoxFilter should maintain its own internal state
`generics`, rather than carrying it as a parameter to local helper
functions.
- Add another boolean state `boolean_state` which represents whether
to ignore the current docstring block (magic lines). This flag will
be reset as soon as the block is end.
Note: As expected, there is no change at all in the current docs
generated, because we have been working around and writing luadoc
comments so that such erroneous docstring resulting from preceding
`@alias` blocks won't appear.

Problem:
We don't enable stylua for many Lua scripts. Automating code-style is an
important tool for reducing time spent on accidental (non-essential)
complexity.
Solution:
- Enable lintlua for `scripts/` directory.
- Specify `call_parentheses = "Input"`, we should allow kwargs-style
function invocations.

Memoizes a function, using a custom function to hash the arguments.
Private for now until:
- There are other places in the codebase that could benefit from this
(e.g. LSP), but might require other changes to accommodate.
- Invalidation of the cache needs to be controllable. Using weak tables
is an acceptable invalidation policy, but it shouldn't be the only
one.
- I don't think the story around `hash_fn` is completely thought out. We
may be able to have a good default hash_fn by hashing each argument,
so basically a better 'concat'.

Everything after a "#" char is a "description" comment, i.e. luals won't
treat it as a type, name, etc. But "#" should not be present in the
generated docs (such as :help docs).

* docs(lua): teach lua2dox how to table
* docs(lua): teach gen_vimdoc.py about local functions
No more need to mark local functions with @private
* docs(lua): mention @nodoc and @meta in dev-lua-doc
* fixup!

feat(lua): add vim.system()
Problem:
Handling system commands in Lua is tedious and error-prone:
- vim.fn.jobstart() is vimscript and comes with all limitations attached to typval.
- vim.loop.spawn is too low level
Solution:
Add vim.system().
Partly inspired by Python's subprocess module
Does not expose any libuv objects.

- Begin using `@package` in place of `@private` for functions
that are accessed internally but outside their defined class.
- Rename Node -> TSP.Node

Problem:
Help tags like vim.treesitter.language.add() are confusing because
`vim.treesitter.language` is (thankfully) not a user-facing module.
Solution:
Ignore the "fstem" when generating "treesitter" tags.

Problem:
Treesitter injections are slow because all injected trees are invalidated on every change.
Solution:
Implement smarter invalidation to avoid reparsing injected regions.
- In on_bytes, try and update self._regions as best we can. This PR just offsets any regions after the change.
- Add valid flags for each region in self._regions.
- Call on_bytes recursively for all children.
- We still need to run the query every time for the top level tree. I don't know how to avoid this. However, if the new injection ranges don't change, then we re-use the old trees and avoid reparsing children.
This should result in roughly a 2-3x reduction in tree parsing when the comment injections are enabled.

Problem:
Nvim has Lua but the "nvim" CLI can't easily be used to execute Lua
scripts, especially scripts that take arguments or produce output.
Solution:
- support "nvim -l [args...]" for running scripts. closes #15749
- exit without +q
- remove lua2dox_filter
- remove Doxyfile. This wasn't used anyway, because the doxygen config
is inlined in gen_vimdoc.py (`Doxyfile` variable).
- use "nvim -l" in docs-gen CI job
Examples:
$ nvim -l scripts/lua2dox.lua --help
Lua2DoX (0.2 20130128)
...
$ echo "print(vim.inspect(_G.arg))" | nvim -l - --arg1 --arg2
$ echo 'print(vim.inspect(vim.api.nvim_buf_get_text(1,0,0,-1,-1,{})))' | nvim +"put ='text'" -l -
TODO?
-e executes Lua code
-l loads a module
-i enters REPL _after running the other arguments_.

This will check if the string after the variable in a @param is either
"number", "string", "table", "boolean" and "function" and if so add a
parenthesis around it. This will help separate the variable type with
the following text. Had all our functions been annotated with emmylua
then a more robust solution might have been preferable (such as always
assuming the third string is parameter type without making any checks).
I believe however this is a clear improvement over the current situation
and will suffice for now.

Breaking Changes:
- Deprecated all `vim.lsp.util.{*diagnostics*}()` functions.
- Instead, all functions must be found in vim.lsp.diagnostic
- For now, they issue a warning ONCE per neovim session. In a
"little while" we will remove them completely.
- `vim.lsp.callbacks` has moved to `vim.lsp.handlers`.
- For a "little while" we will just redirect `vim.lsp.callbacks` to
`vim.lsp.handlers`. However, we will remove this at some point, so
it is recommended that you change all of your references to
`callbacks` into `handlers`.
- This also means that for functions like |vim.lsp.start_client()|
and similar, keyword style arguments have moved from "callbacks"
to "handlers". Once again, these are currently being forward, but
will cease to be forwarded in a "little while".
- Changed the highlight groups for LspDiagnostic highlight as they were
inconsistently named.
- For more information, see |lsp-highlight-diagnostics|
- Changed the sign group names as well, to be consistent with
|lsp-highlight-diagnostics|
General Enhancements:
- Rewrote much of the getting started help document for lsp. It also
provides a much nicer configuration strategy, so as to not recommend
globally overwriting builtin neovim mappings.
LSP Enhancements:
- Introduced the concept of |lsp-handlers| which will allow much better
customization for users without having to copy & paste entire files /
functions / etc.
Diagnostic Enhancements:
- "goto next diagnostic" |vim.lsp.diagnostic.goto_next()|
- "goto prev diagnostic" |vim.lsp.diagnostic.goto_prev()|
- For each of the gotos, auto open diagnostics is available as a
configuration option
- Configurable diagnostic handling:
- See |vim.lsp.diagnostic.on_publish_diagnostics()|
- Delay display until after insert mode
- Configure signs
- Configure virtual text
- Configure underline
- Set the location list with the buffers diagnostics.
- See |vim.lsp.diagnostic.set_loclist()|
- Better performance for getting counts and line diagnostics
- They are now cached on save, to enhance lookups.
- Particularly useful for checking in statusline, etc.
- Actual testing :)
- See ./test/functional/plugin/lsp/diagnostic_spec.lua
- Added `guisp` for underline highlighting
NOTE: "a little while" means enough time to feel like most plugins and
plugin authors have had a chance to refactor their code to use the
updated calls. Then we will remove them completely. There is no need to
keep them, because we don't have any released version of neovim that
exposes these APIs. I'm trying to be nice to people following HEAD :)

Judging class definitions in the form "string.find (line, '=% s * class% (')"
must force writing class definitions in this format, but such a mechanism is Absent.
Also, Lua has no formal class in the language specification, and implements inheritance with setmetadable.
To detect this, we should have a parser for it, not a simple regular expression.
