Subject: Initialize the private send_lock. (camel_transport_finalize): Free
 the

2001-06-27  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-transport.c (camel_transport_init): Initialize the private
	send_lock.
	(camel_transport_finalize): Free the private send_lock.
	(camel_transport_get_type): Set the init and finalize functions.
	(camel_transport_send): Lock the transport.
	(camel_transport_send_to): Same.

	* camel-private.h: Add CAMEL_TRANSPORT_(UN)LOCK macros.
