Fixed "proxy_pass" with IP address and no port (ticket #276). Upstreams created by "proxy_pass" with IP address and no port were broken in 1.3.10, by not initializing port in u->sockaddr. API change: ngx_parse_url() was modified to always initialize port (in u->sockaddr and in u->port), even for the u->no_resolve case; ngx_http_upstream() and ngx_http_upstream_add() were adopted.
