Added some operation progress reporting. Actual data transfer is 'tricky'

2001-07-23  Not Zed  <NotZed@Ximian.com>

	* providers/smtp/camel-smtp-transport.c (smtp_auth, smtp_helo,
	send_to): Added some operation progress reporting.  Actual data
	transfer is 'tricky' because of the layers used.
	(smtp_auth): Instead of checking exception_is_set, use
	challenge==NULL to test if sasl_challenge_base64 failed.

	* providers/local/camel-mbox-summary.c (mbox_summary_sync): Remove
	peters changes below and put in a better fix.  These functions
	already return -1 on error, just use that, and not worry about
	building our own exception redundantly.

	* camel-service.c (camel_get_host_byname): Turn the progress into
	a transient event.
