This generalizes diagnostic handling outside of just the scope of LSP.
LSP clients are now a specific case of a diagnostic producer, but the
diagnostic subsystem is decoupled from the LSP subsystem (or will be,
eventually).

Follow-up to 8969efca8 (Vim patch 8.1.0723)
NOTE: This changes the main entrypoint for running single oldtest files
to not use/require the ".res" extension anymore. But it is handled for
B/C.
Adds a phony rule to run oldtest by filename.
Not going through "$(MAKE)" avoids GNUmakefile being used then (which I
use for WIP things), and it seems like SINGLE_MAKE should be used anyway
probably.
luassert uses 3 by default, which is often not enough.
Instead of documenting how to increase it, let's use a more fitting
(sane) default of 100 levels.
- Move .luacheckrc to root, add read_globals=vim
- Simplify lualint target, run it on all lua files
- Lint preload.lua, but ignore W211
- Remove testlint target, included in lualint (and lint)
- Clean up .luacheckrc
