Non-blocking Read on Windows

[gflohr]

In the "Known Issues" section of the docs, you mention that the extension does not work on Windows because you could not find a way to do non-blocking reads from stdin on that platform.

I had faced a similar problem for Qgoda, where I had to asynchronously read from multiple child processes and the file system polling API in parallel. After a lot of try-and-error, I finally found a comparably simple solution that is described here: http://www.guido-flohr.net/platform-independent-asynchronous-child-process-ipc/

Thanks very much for sharing this. I remember this way to talk to child processes from my time when did C programming for windows, but as far as I see it does not solve the problem, that the language server itself needs to read from stdin in a non blocking way to get it's commands from vscode. I know there are ways to do it in C code, but actually I do no Perl programming on windows anymore, so because of my limited time I am not able to do further investigation in this direction and as you said it takes a lot of time to figure this out. So I am happy to include any patches, but will not yet do it on my own.
