Alternate Services is not implemented when behind a proxy. For the general http:// case its not possible, as the proxy is given just the origin name and an Alt-Service needs both a 'route' and an origin.

however, SOCKS and HTTPS connect are actually routes. And these proxies are not aware of http semantics inside the TLS, so they don't need the origin.

This patch adds SOCKS support. SOCKS and Alt-Svc support is particularly interesting for the tor protocol as a way to route to tor protocol .onion native (non-exit) services without changing origins/bookmarks/links.

nit: let's space out i=0 since we're here.

Let's add a comment regarding what `acceptable` means in this context, and what we use it for.
Also mention that it returns true when passed a null pointer.
