1. Fully populate layer records for mapped image top layers …

   When we create a copy of an image's top layer that's intended to be
   identical to the top layer, except for having some set of ID mappings
   already applied to it, copy over the template layer's compressed and
   uncompressed digest and size information, compression information,
   tar-split data, and lists of used UIDs and GIDs, if we have them.
   
   The lack of sizing information was forcing ImageSize() to regenerate the
   diffs to determine the size of the mapped layers, which shouldn't have
   been necessary.
   
   Teach the overlay DiffGetter to look for files in the diff directories
   of lower layers if we can't find them in the current layer, so that
   tar-split can retrieve content that we didn't have to pull up.
