Move the handling of compressed data out of macro-handling-specific code. - This cleans up the code by separating out unrelated code. - This makes it much easier to e.g. change from zlib to some other compression format (which could even be host-specific), and abstracts the representation of a compressed data unit. - Allows future reuse for other purposes.
