Version 3 for DPkg::Pre-Install-Pkgs with MultiArch info

Version 3 for DPkg::Pre-Install-Pkgs with MultiArch info

Adds on top of Version 2 to all displayed version numbers the
architecture as well as the MultiArch flag for consumption by the hooks.

Most of the time the architecture will be the same for both versions
displayed, but packages might change from "all" to "any" (or back)
between versions so we can't display the architecture for packages.

Pseudo-Format for Version 3:
<name> <version> <arch> <m-a-flag> <compare> <version> <arch> <m-a-flag>

Examples:
stuff - - none < 1 amd64 none **CONFIGURE**
libsame 1 i386 same < 2 i386 same **CONFIGURE**
stuff 2 i386 none > 1 i386 none **CONFIGURE**
libsame 2 i386 same > - - none **REMOVE**
toolkit 1 all foreign > - - none **REMOVE**
