libsisyphus :

  - implement binary package cache auto cleaning mechanism
  - stop relying on a portage hook to clean up the binary package cache
  - although the portage hook works OKish, it has some severe limitations :
    - it is not aware of partial downloads (it can never be, since sisyphus doesn't rely on portage but uses it's internal mechanism to download binary packages)
    - the cleaning itself is only partial, leaving empty directories behind
    - if a previous cleaning has failed (keyboard interrupt), it will confuse the dependency resolver
