Description
It would be a great thing to be able to send HTTP 103 headers aka early hints using njs, actually, tryed using
r.headersOut['Link'] = '</style.css>; rel=preload; as=style';
r.headersOut['Link'] = '</script.js>; rel=preload; as=script';
r.return(103, "");
in js_content or when setting a variable with js_var...
but got error curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)
makes sens, so needs internal support for this?

Research direction
Start by examining how response headers are handled from js_content and when setting a variable with js_var., including r.headersOut and the attempted HTTP 103 response. Determine the internal support needed for early hints so the HTTP/2 request completes without a PROTOCOL_ERROR; done means njs can send HTTP 103 headers correctly.
