Takes the next pending connection from the listening socket s and returns it with the peer's IPv4 address.
A blocking listener waits for a connection. A non-blocking one returns INVALID_SOCKET at once when none is pending,
and get_last_socket_error() then equals SOCKET_WOULDBLOCK; any other error also gives INVALID_SOCKET, with the
address left zeroed. The returned socket is owned by the caller, who releases it with close_and_reset. Whether it
starts in non-blocking mode depends on the platform, so call set_blocking to pick one explicitly. Use accept_v6
for a listener bound to an IPv6 address; an IPv4 record cannot hold an IPv6 peer.
