The horrible effects of human slavery continue to impact society. The casual use of the term "slave" in computer software is an unnecessary reference to a painful human experience. This commit removes all possible references to the term "slave". Implementation notes: The zpool.d/slaves script is renamed to dm-deps, which uses the same terminology as `dmsetup deps`. References to the `/sys/class/block/$dev/slaves` directory remain. This directory name is determined by the Linux kernel. Although `dmsetup deps` provides the same information, it unfortunately requires elevated privileges, whereas the `/sys/...` directory is world-readable.
