Setup the Trash folder.

2001-02-14  Jeffrey Stedfast  <fejj@ximian.com>

	* component-factory.c (owner_set_cb): Setup the Trash folder.

	* mail-ops.c (create_trash_vfolder): Do better error handling.
	(populate_folder_urls): Oops, helps to strdup the url into the
	array if we plan on freeing the data.
	(mail_get_trash): New async function that may eventually replace
	mail_do_setup_trash().
	(do_setup_trash): Do better error handling.

	* mail-local.c (mail_local_store_class_init): Override
	get_folder_info.
	(get_folder_info): Implement.
