Now that our socket system call polyfills are good enough to support Musl's DNS library we should be using that rather than the barebones domain name system implementation we rolled on our own. There's many benefits to making this change. So many, that I myself wouldn't feel qualified to enumerate them all. The Musl DNS code had to be changed in order to support Windows of course, which looks very solid so far
