* 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. svn path=/trunk/; revision=2797
