Upstream: detect port absence in fastcgi_pass with IP literal. If fastcgi_pass (or any look-alike that doesn't imply a default port) is specified as an IP literal (as opposed to a hostname), port absence was not detected at configuration time and could result in EADDRNOTAVAIL at run time. Fixed this in such a way that configs like http { server { location / { fastcgi_pass 127.0.0.1; } } upstream 127.0.0.1 { server 10.0.0.1:12345; } } still work. That is, port absence check is delayed until after we make sure there's no explicit upstream with such a name.
