Meta server: add missing pointer initialization in the meta authentication op constructor. Fix lookup op handling. Short circuit authentication negotiation (special type of lookup) and authenticate ops in the ClientSM. Fix AuthConetext op verification logic. Fix authentication op response by adding the missing empty line after the headers.
Kfsio lib: change filter insertion method to allow to report errors. SslFilter:  fix error handling, properly handle io retry and errors in ssl fitter insertion in SSL_connect or SSL_accept calls, as these actually do non blocking socket io.
Meta server and client lib: Add error handling and reporting for [ssl] filter insertion into connection object to handle ssl initialization and handshake errors. Update connection state after successful insertion of the filter as the connection read/write desire/flags might change.
X509 client / meta server authentication method is now working.
