Convenience function which creates a SOCK_STREAM type socket
bound to *address* (a 2-tuple (host, port)) and return the socket
object.
*family* should be either AF_INET or AF_INET6.
*backlog* is the queue size passed to socket.listen().
*reuse_port* dictates whether to use the SO_REUSEPORT socket option.
*dualstack_ipv6*: if true and the platform supports it, it will
create an AF_INET6 socket able to accept both IPv4 or IPv6
connections. When false it will explicitly disable this option on
platforms that enable it by default (e.g. Linux).
