Support new deb formats

Goal description

Have all packages in the archive buildable using the new source package formats. Specifically 3.0 (quilt) for now, maybe others in the future.

There's more detailed information in its project page

Current status

2010-05-25: this release goal has been dropped because the dpkg team no longer plans to change the default format. Instead maintainers have to be explicit about the source format chosen because debian/source/format will become mandatory. Tracked in http://lintian.debian.org/tags/missing-debian-source-format.html.
