Subject: [BREAK] add possibility to download and use multiply Translation
 files, configurable with Acquire::Languages accessable with
 APT::Configuration::getLanguages() and as always with documentation in

Subject: Implement the first step toward Multi-Arch by setting up a Group
 infrastructor for packages.

APT is now aware of the fact that a package A in architecture X can't
satisfy a dependency on package A in architecture Y - to handle these
packages are now identified by name and architecture, so different
architectures of the same package are handled internally as completly
different packages. This is great for pinning, dependency checking and
in many other situations, but sometimes we need to know which archs are
available for a given package: Here Groups come to our rescue!

From 5dd4c8b811d9c7bc33e50254811f5bc0fc37f872 Mon Sep 17 00:00:00 2001
From: David Kalnischkies <kalnischkies@gmail.com>
Date: Wed, 23 Dec 2009 12:38:19 +0100
Subject: merge Goswin Brederlow "support download of index files for different
 archs" patch which includes the following big changes: - Declare the unused
 [vendor] field in sources.list as option field,   e.g. deb [arch=amd64,i386
 lang=en_GB have=fun] http://example.org - When fetching index files download
 them for all APT::Architectures   (overrideable with the options field above)
 - Allow all architectures of APT::Architectures to be in the Cache - Add the
 architecture to status and progress informations - Add b= (Binary
 architecture) to policy

This commit doesn't incude the "pin-hack" as the Group structure will take
care of this (and does it already to some extend).

Subject: Split ListParser::NewDepends into two methods to use these new method
 for creating the dependencies needed for our groups: For now for all groups
 only one package can be installed at the same time which conflicts with each
 other packages in the group. The exceptions are architecture all package.

Also, the Multi-Arch field is now parsed, but not used for now.

Subject: Add yet another pseudo package which isn't as pseudo as the others:
 Arch all packages are now represented by arch depending packages which all
 depend on a package with the same name and the special arch "all". This
 packages has NO dependencies, but beside this the same information. It is the
 only package which has a size, the arch depending ones all have a zero size.
 While the arch depending pseudo packages are used for dependency resolution
 the arch "all" package is used for downloading and ordering of the package.

Subject: move ShowPkg() from apt-get to the PkgIterator and rename it to
 FullName() responseable for displaying a package name and the architecture in
 a uniform way. Pretty option can be used to not append the architecture if it
 is the native architecture or all - and use it all over the place in the
 commandline tools.
