Subject: [PATCH 1/2] Add `IP_PORTRANGE*` constants to the socket module

`IP_PORTRANGE*` can be used for getting/setting port ranges on a per socket
basis, as opposed to a system wide basis, in conjunction with calls like
`socket.getsockopt` and `socket.setsockopt`.

This functionality is available on \*BSD and Linux.
