* apt/progress/__init__.py:

  - add update_status_full() that takes file_size/partial_size as 
    additional callback arguments
  - add pulse_items() that takes a addtional "items" tuple that 
    gives the user full access to the individual items that are
    fetched
* python/progress.cc:
  - low level code for update_status_full and pulse_items()
  - better threading support

* aptsources/distro.py:
  - fix indent error that causes incorrect sources.list additons
    (LP: #372224)
* python/progress.cc:
  - fix crash in RunSimpleCallback()
* apt/cache.py:
  - when the cache is run with a alternative rootdir, create
    required dirs/files automatically
