		the get_fqdn() call done to get canonical name when
		checking an SSL certificate is blocking, which is
		sad as we just did a non-blocking lookup to connect.
		Fix that by letting the fqdn available to the SockInfo,
		and use that in ssl_certificate_check(). For IMAP,
		we don't do it as the lookup's done by libetpan, but
		it's less annoying as IMAP connections as much more
		rare than POP3 connections.
