Port number is dropped from `Location:` header as parsed by client

[kmcallister]

Steps to reproduce:

$ printf 'HTTP/1.0 301 Moved Permanently\r\nLocation: http://localhost:8080/foo\r\n\r\n' | nc -l -p 8080 &
$ RUST_LOG=net::http_loader ./servo http://127.0.0.1:8080

Servo sees a header.header_value() of http://localhost/foo which is not what the server sent.

I can also reproduce this with the included example client.

$ printf 'HTTP/1.0 301 Moved Permanently\r\nLocation: http://localhost:8080/foo\r\n\r\n' | nc -l -p 8001 &
$ ./build/examples/client/client 
Yay! Started to get the response.
Status: 301 Moved Permanently
Headers:
 - Location: http://localhost/foo

That header is handled with extra::url::Url's FromStr and ToStr implementations.

extra::url::to_str doesn't do anything with the port. This is defective behaviour!
