Request for review: 7198416: Using X500Name in place of CertificateIssuerName and CertificateSubjectName

[Jason Uh]

http://cr.openjdk.java.net/~juh/7198416/webrev.00/
Because sun.security.x509.CertificateIssuerName and 
CertificateSubjectName do not provide any functionality beyond that of 
X500Name, they have been removed. X509CertImpl and X509CertInfo have 
been modified to use X500Name directly instead of these classes.

Thanks,
Jason
