Since Mac OS X El Capitain (v10.11), Apple uses LZFSE compression to 
generate compressed DMGs as an alternative to BZIP2. Possible, Apple
want to keep this algorithm as default in long term. Some years ago, 
Apple opened the LZFSE algorithm to opensource and the main source (or 
the most active repo), can be found at: https://github.com/lzfse/lzfse

v1-v2: Fixing some error handlings from dmg-lzfse.c
v2-v3: Master rebasing suggestion from Stefan.

Julio Faracco (4):
  block: adding lzfse decompressing support as a module.
  configure: adding support to lzfse library.
  dmg: including dmg-lzfse module inside dmg block driver.
  dmg: exchanging hardcoded dmg UDIF block types to enum.

Thanks, applied to the block-next branch (for 3.2).

Stefan, if you have some more comments, we can still modify/dequeue the
patches, but this seems to address all of my review comments for v1.
