    ip: add ip_sockaddr, update functions converting to/from endpoints
    
    Clean up the code unionising sockaddr, sockaddr_in and sockaddr_in6.
    Don't assume that an ip_address contains a sockaddr.
    
    Replace {sockaddrof,socaddrlenof)() with (new) endpoint_to_sockaddr().
    Test the round trip sockaddr_to_endpoint() -> endpoint_to_sockaddr().
