JDK 8 Code review request for 7179715: Reason of CertPathValidatorException should be UNDETERMINED_REVOCATION_STATUS if OCSP request failed

[Sean Mullan]

Please review my webrev for 7179715:

http://cr.openjdk.java.net/~mullan/webrevs/7192896/webrev.00/

The bugid is not accessible for some reason. Essentially this is a simple fix to
set the reason of the CertPathValidatorException to
UNDETERMINED_REVOCATION_STATUS if a network failure prevents us from determining
if a certificate has been revoked or not.

Thanks,
Sean
