Treat "//some_path" as pathname rather than hostname by default.

Note that "//" is still a special indicator for the hostname, and this does
not change the parsing of mailto: and other "slashless" url schemes.  It
does however remove some oddness in url.parse(req.url) which is the most
common use-case for the url.parse function.
