Backporting the TCP loopback fast path (Windows) improvement to OpenJDK v7

[Seán Coffey]

Alan,

hadn't spotted the race issue. I guess we could delay setting 
ver_initialized until OSVERSIONINFO is populated.
Alternatively - like you say, I think we can revert back to the simpler 
edit :

http://cr.openjdk.java.net/~coffeys/webrev.8060170.7u.v2/webrev/
I'll run with this version unless I hear objections.

regards,
Sean.
