[8] 7174966: With OCSP enabled on Java 7 get error 'Wrong key usage' with Comodo certificate

[Vincent Ryan]

Please review the fix for: http://bugs.sun.com/view_bug.do?bug_id=7174966

The problem occurs when validating the signature of an OCSP response from the Comodo CA.
The Signature class tests for the presence of the digitalSignature keyUsage setting when examining
a signer's certificate. One solution is for the sun.security.provider.certpath.OCSPResponse class to
pass the signer's public key rather than the signer's certificate.
