This commit removes the `Handle` argument from the following constructors * `TcpListener::bind` * `TcpStream::connect` * `UdpSocket::bind` The `Handle` argument remains on the various `*_std` constructors as they're more low-level, but this otherwise is intended to set forth a precedent of by default not taking `Handle` arguments and instead relying on the global `Handle::default` return value when necesary.
