New files to handle the LOGIN SASL mechanism.

2001-04-01  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-sasl-login.[c,h]: New files to handle the LOGIN SASL
	mechanism.

	* camel-sasl-plain.c: Removed the definition of
	camel_sasl_login_authtype.

	* camel-sasl.c (camel_sasl_new): Oops. I thought LOGIN was an
	alias to PLAIN. I was wrong. These two SASL objects have to be
	separate.

	* providers/smtp/camel-smtp-transport.c (smtp_auth): Updated to
	check for and use authmech->quick_login when available.
