This change introduces the implementation of the SSLConnection methods
getpeercert and cipher. The following has been added:
* dtls.util: utility elements shared by other modules in this package
* dtls.x509: a module for X509-certificate-related functionality,
including formatting a certificate into a Python
dictionary as prescribed by the Python standard
library's ssl module; functionality for testing with
PEM-encoded certificates in the file system is included
* yahoo-cert.pem: the current certificate of www.yahoo.com: this is a good
testing certificate, since it contains the subject
alternate name extension
Other notable changes:
* sslconnection: private attributes are now preceded by "_"
* openssl: null-ness in opaque FuncParam-derived return values is
now properly detected and an exception is raised as
expected
