RFR: JDK-8040810 - Uninitialised memory in jdk/src/windows/native/java/net: net_util_md.c, TwoStacksPlainSocketImpl.c, TwoStacksPlainDatagramSocketImpl.c, DualStackPlainSocketImpl.c, DualStackPlainDatagramSocketImpl.c

[Mark Sheppard]

Hi
    please oblige and review the following changes
http://cr.openjdk.java.net/~msheppar/8040810/webrev/

which address the issue raised in

https://bugs.openjdk.java.net/browse/JDK-8040810

resulting from static code analysis.

these changes explicitly initialize local function variables, which are 
in the main
out parameters to other function calls and hence are set within the 
called function.
It can be reasonably argued that the initialization is unnecessary, but 
current coding
guidance is to perform the initialization

regards
Mark
