The "flat phys" feature will use only a single phys slot for all entries, which means the old "single", "double" etc naming now makes no sense, and more importantly, means that choosing the right slot for a given block pointer will depend on how many slots are in use for a given DDT. This removes the old names, and adds accessor macros to decouple specific phys array indexes from any particular meaning. (These macros look strange in isolation, mainly in the way they take the ddt_t* as an arg but don't use it. This is mostly a separate commit to introduce the concept to the reader before the "flat phys" commit extends it).
