Just for clarity ( since Igor may need to some further work here ), I added a test library version of NetworkConfiguration that is used by the java.net tests, several of them iterate over network interfaces in a slightly different way. The version I added was subtly different from the version that Alan added in the NIO test subdirectory, so I did not change the NIO test tree in any way.

I did not review the consolidation of these files when the move to the top-level repo happen, I will need to recheck the changsets to find out what happened.
