No longer takes a stls_supported argument since we no longer need it with

2002-03-18  Jeffrey Stedfast  <fejj@ximian.com>

	* providers/pop3/camel-pop3-store.c (connect_to_server): No longer
	takes a stls_supported argument since we no longer need it with
	the new logic.
	(connect_to_server_wrapper): New logic: First try connecting to
	the SSL port (995 by default), if that fails with
	SERVICE_UNAVAILABLE, then we attempt to connect (to port 110 by
	default) and try to use STARTTLS.
