This catches output dependency violations, e.g. two threads doing a read-modify-write without synchronization. New struct emptypedstr member seqno. Make sure all members of unit empobj_storage share it. Set it in ef_blank() and ef_set_uid(), step it in ef_write(). fairland and files don't use ef_set_uid(); need to set it manually in files.c's main() and file_sct_init(). Factor do_read() out of fillcache() to make it available for new get_seqno().
