2001-02-23  Not Zed  <NotZed@Ximian.com>

        * mail-ops.c (create_folder_get): Make op cancellable/report
        internals.
        (get_folder_get):
        (sync_folder_sync):
        (get_folderinfo_get): Make op cancellable/report internals.

        * mail-vtrash.c (get_trash_get): Setup the operation registration,
        and create a pseudo "start/stop" operation.

        * component-factory.c (owner_set_cb): Make trash creation async.

        * mail-local.c (register_folder_desc): A description of what we're
        doing.

        * mail-mt.c (mail_msg_new): Set status callback to operation_new.
        (mail_operation_status): Operation status function, proxy messages
        to main thread, and attempt to present a meaningful ui experience
        for operations.
