Older python-apt modules don't export Package.installed_files and there
seems to be no other way to figure out if a package is
removed-but-not-purged, so we just always assume it's purged.

A package may be removed but not purged with APT. The only way to
identify this state is by looking at the list of installed files of
a package. Even if the package has no files installed, this list will be
non-empty until the package is removed:

  # python -c "import apt; c=apt.Cache(); c.update(); c.open(); p=c['ruby1.8']; print p, p.installed, p.installed_files"
  <Package: name:'ruby1.8' id:1425> None [u'']

  # dpkg --purge ruby1.8
  (Reading database ... 27904 files and directories currently installed.)
  Removing ruby1.8 ...
  Purging configuration files for ruby1.8 ...

  # python -c "import apt; c=apt.Cache(); c.update(); c.open(); p=c['ruby1.8']; print p, p.installed, p.installed_files"
  <Package: name:'ruby1.8' id:1425> None []

See http://bugs.debian.org/712749 too.

If a package is not marked installed but it still 'has_files', then it
should be processed if the request is to purge it.

name is used throughout Ansible, it's the "standard". This change
applies that standard to the add_host routine and updates the docs to
reflect that. Related to https://github.com/ansible/ansible/pull/3254

The django 'migrate' command should receive the --noinput command,
otherwise it can block waiting for user input.

On machines with multiple pci domains get_device_facts would fail to
find a matching pci device causing setup to fail. Also on some platforms
there is additional information between the pci information and 'host'.
Modified get_device_facts to call lspci with the -D option and modified
the regex to account for the pci domain and to be more selective.

bug fix for #3077, environment settings for script

changed get_mount_facts to ignore mount types 'none'

Fix typo in PKGBUILD

spelling ansbile->ansible

You can use apt module with update_cache and without specifying a
package. Update the docs to reflect this.
