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).
