* all get()/set() calls to CertificateExtensions and CRLExtensions
is by OID
* get()/set() from X509CertImpl/Info continue to work by name.
ex: X509CertImpl.get("x509.info.extensions.<name>")
* a global nameCache is maintained in OIDMap as suggested
* no IOException from CRLExtensions
* fixed a bug on line 753 of X509CertImpl to allow extension deletion
Thanks,
Jason

Currently, when certificates are parsed, the extensions are added using the name, and when they are retrieved, they are also specified by name -- for example, X509CertImpl.getBasicConstraints() calls a get() method with the BasicConstraints alias as the lookup parameter.
