RFR[8243408]: 'Inconsistent Exceptions are thrown by MulticastSocket when sending a DatagramPacket to port 0'

[Patrick Concannon]

Hi,

Could someone please review my fix for JDK-8243408 'Inconsistent 
Exceptions are thrown by MulticastSocket when sending a DatagramPacket 
to port 0'?

Currently, MulticastSocket.send(DatagramPacket, byte) throws an 
IOException when sending to port 0 on Unix and macOS, but doesn’t throw 
on Windows and Solaris.
This fix adds a check for port == 0 to MulticastSocket's 2-arg send 
method to ensure a consistent exceptionis thrown across platforms, i.e. 
a SocketException. This follows on from a similar change made to the 
DatagramSocket and DatagramChannel's send method. See JDK-8240533 
<https://bugs.openjdk.java.net/browse/JDK-8240533> for more details
