Patch for adding SO_REUSEPORT socket option

[Lu, Yingqi]

Hi Alan and Michael,

Thank very much to both of you for your feedback.

Currently, I think the only platform that does not have SO_REUSEPORT is Windows. As Michael mentioned, API allows this possibility by throwing SocketException with message "Invalid option". Older kernel that does not support the feature throws SocketException with message "Protocol not available".

By the way, I just got notified that the second version is also uploaded. I put it here as well in case you want to take a look and compare. However, I agree, standard socket option may be a better way to implement. Please let us know your feedback.

Here is the first version (standard socket option): http://cr.openjdk.java.net/~mcberg/jdk/6432031/webrev.01/

Here is the second version (extended socket option): http://cr.openjdk.java.net/~mcberg/jdk/6432031/webrev.02/

All, please take some time to review the patches and let us know your feedback and comments!

Thanks,
Lucy

P.S. Based on Alan Baleman's comment on JBS, we are in meanwhile working on adding this option to 'java.net.ExtendedSocketOption'.

My comment in the bug was just to bring up the question as to whether this should be a standard or JDK-specific socket option. If it is consistently implemented on most platforms then having in the standard API make sense.
