* merged patch from Samuel Lidén Borell to fix crash if there utf8

  in the control file (LP: #624290) and add test
* apt/cache.py:
  - add "sources_list" parameter to cache.update() to force updating
    a single sources.list entry only
* debian/control:
  - add missing build-depends on python-debian (needed to run the
    tests for apt.debfile.DebPackage()
* apt/debfile:
  - don't fail if we conflict with the pkgs we are reinstalling
