in NSS if Python programmer forgot to call one of the NSS
initialization routines.
Rename the classes X500Name, X500RDN, X500AVA to DN, RDN, AVA
respectively.
DN and RDN objects now return a list of their contents when indexed by
type, this is to support multi-valued items.
Fix bug where AVA object's string representation did not include it's
type.
Enhance test/test_cert_components.py unit test to test for above
changes.
