On connection failure, unref the tcp stream.
2002-05-27 Jeffrey Stedfast <fejj@ximian.com> * providers/smtp/camel-smtp-transport.c (connect_to_server): On connection failure, unref the tcp stream. * providers/pop3/camel-pop3-store.c (connect_to_server): On connection failure, unref the tcp stream. * providers/imap/camel-imap-store.c (connect_to_server): On connection failure, unref the tcp stream. * providers/nntp/camel-nntp-store.c (nntp_store_query_auth_types): Our parent class is no longer CamelRemoteStore. (nntp_store_init): Same. (camel_nntp_store_get_type): Here too. (nntp_connect): Rewritten to try to connect via SSL. Also remove code using CamelRemoteStore. (camel_nntp_command): Don't call camel_remote_store_connected(). svn path=/trunk/; revision=17022
