Need reviewers - another set of network regression sets patches

[Pavel Tisnovsky]

Hi all,

I've made another set of changes in network regression tests for 
OpenJDK6 and prepared them for review here:
http://cr.openjdk.java.net/~ptisnovs/JavaNetJTregTests2/

These changes only improve the test themselves (no new functionality 
were added), mainly in these areas:

1) the tests are properly closing opened ports, sockets, input streams etc.
2) some tests started in their own JVM (so they don't change environment 
for other tests)
3) some shellscripts are updated to work in Cygwin environment

All changes are based on OpenJDK7 versions of regression tests.

Can anyone please review the changes?

Thank you in advance,
Pavel
