RFR: 8233319: Deprecate MulticastSocket methods that operate on java.net.InetAddress

[Julia Boes]

Hi,

Please see this fix that deprecates methods of MulticastSocket.
These methods either operate on InetAddress instead of NetworkInterface 
or work with SocketOptions.IP_MULTICAST_LOOP instead of 
StandardSocketOptions.IP_MULTICAST_LOOP.
