Lsp-mode: Feature: flymake integration

[yyoncho]

This will help lsp-mode to become usable without additional extensions(refer to #318 )

[innerout]

This could be a problem for people that cannot install emacs 26.1 or build it from source. Am i wrong?

[yyoncho]

@innerout you are right - flymake integration will be optional and only for emacs 26.1+.

[innerout]

Could flymake integration potentially solve the problems flycheck has when changing an lsp buffer fast?

[yyoncho]

I am not aware of that issue, can you provide PR?

[innerout]

I am using mainly ccls and cquery so i don't know if this is happening to all lsp-servers.We were talking about it with @MaskRay you can ask him. Probably he has a better understanding for the source of the problem.

[MaskRay]

This may be useful. eglot's implementation may give some insights.

@innerout I'll let you disappointed :( I don't know the source of problem well.

... and FlyCheck lost it most prominent/active maintainer

[yyoncho]

If there are no volunteers for the task i will hit it after migration to lsp.el is over and when i sync lsp java with the new jdt ls changes.

[yyoncho]

I will work on that.
