Patch for adding SO_REUSEPORT socket option

[Lu, Yingqi]

Hi Alan,

I heard that the feature freeze for OpenJDK9 is approaching. Given the significant performance impact (up to 1.93x with Hadoop Distributed File System) this feature provides and the status of the existing work, we would be really interested in see this feature to be approved for OpenJDK9. We will surely continue working with the community to address opens/issues until it is completely ready to be merged into the source code tree. 

Please let us know what you think.

Thanks,
Lucy

Off by disabled make sense to me.
