Merged python-apt consolidation branch by Sebastian

Heinlein (many thanks):
* apt/cache.py:
  - new method "isVirtualPackage()" 
  - new method "getProvidingPackages()"
  - new method "getRequiredDownload()"
  - new method "additionalRequiredSpace()"
* apt/debfile.py:
  - move a lot of the gdebi code into this file, this
    provides interfaces for querrying and installing
    .deb files and .dsc files
* apt/package.py:
  - better description parsing 
  - new method "installedFiles()"
  - new method "getChangelog()"
* apt/gtk/widgets.py:
  - new gobject GOpProgress
  - new gobject GFetchProgress
  - new gobject GInstallProgress
  - new gobject GDpkgInstallProgress
  - new widget GtkAptProgress
* doc/examples/gui-inst.py: 
  - updated to use the new widgets
* debian/control:
  - add suggests for python-gtk2 and python-vte
* setup.py:
  - build html/ help of the apt and aptsources modules
    into /usr/share/doc/python-apt/html
* data/templates/Ubuntu.info.in:
  - updated to fix ports.ubuntu.com for powerpc and lpia
    (LP: #220890)
* aptsources/distro.py:
  - add parameter to get_distro() to make unit testing easier
* tests/test_aptsources_ports.py:
  - add test for arch specific handling (when sub arch is on
    a different mirror than "main" arches)
* python/acquire.cc (GetPkgAcqFile): Support DestDir and DestFilename.
