code review request: 8012971 PKCS11Test hiding exception failures

[Anthony Scarpino]

I need a code review for some test changes.  They include the follow bugs:
JDK-8012971 PKCS11Test hiding exception failures
JDK-7193793 sun/security/pkcs11/ec/TestECDH.java failing intermittently
JDK-7198198 sun/security/pkcs11/ec/ReadCertificates.java fails on Suse Linux

A significant change is reading the NSS version. The test can now avoid 
old NSS libraries or a bug in a version of NSS that generate false jdk 
failures.  This greatly helps ECC support and curve support are varied.

The fix to expose the exceptions that were being hidden did generate new 
test failures that already had filed bugs.  The failures were added to 
the ProblemList.
