Ability to get remote port

[elan]

Is there a reason there's no us_socket_remote_port to sit alongside us_socket_remote_address? Perhaps I'm missing something and there's another way to obtain that data.

us_socket_remote_address is there so adding us_socket_remote_port is welcome. Nobody has requested such a function before. You want to know the ephemeral port?

[elan]

yeah, just to be able to key a remote connection based on remote address and port, e.g.

[ghost]

us_socket_local_port and us_socket_remote_address should be replaced with functions that return both IP and port in one go.

us_socket_local_address and us_socket_remote_address are better names

I added it in PR.
