    CPPXT-110 test for code changes to OpenSSLCryptoKeyEC
    
        https://issues.shibboleth.net/jira/browse/CPPXT-110
    
    Load a hand crafted <ds:keyInfo> EC.
    Load an EC cert/key via openssl
    Sign with the latter and verify with the former.
    (because there is no obvious easy visibility on the contents of
    an OpenSSL EC and it makes my head hurt)
