Release Note: New Network Interface Names on Windows - Resolved

Description

Currently we have 2 distinct implementations of NetworkInterface functions on Windows. 
One dates back to pre-WinXP, where there was no support for IPv4. This version is still used when IPv6 stack is disabled with java.net.preferIPv4Stack=true system property.
The other implementation uses WinXP functions that support IPv6. This version is used by default.

We should aim to have only one implementation of these functions. Windows 2000 is no longer supported, so we could use the more modern functions, and filter out IPv6 when IPv4 stack is requested.
