New function to replace camel_provider_scan. Returns a list of either (a)

        * camel-session.c (camel_session_list_providers): New function to
        replace camel_provider_scan. Returns a list of either (a) all
        currently-loaded providers, or (b) all available providers.

        * camel-url.[ch]: Add an "empty" flag to CamelURL (indicating that
        it contains only a protocol).

        * camel-service.c (camel_service_query_auth_types): Make this take
        a CamelException (since it may have to try to connect to the
        server, and it might not able to.)

        * providers/pop3/camel-pop3-store.c: add KPOP (Kerberized POP)
        support. This is mostly so I have two kinds of authmech to play
        with instead of just one. (But it does actually work.)

        * providers/smtp/camel-smtp-transport.c (query_auth_types): update
        for prototype change, but disable the functionality, since it
        doesn't really support any auth types yet.
        (camel_smtp_transport_get_type): add an object init function to
        set the service url_flags.
