[UNSTABLE][PATCH 1/2] UBUNTU: [Packaging] Switch to 3.0 dpkg source formats

[Dimitri John Ledkov]

This patch switches packaging to 3.0 dpkg source formats. Using native
(no orig-tarball) for RC releases, and quilt (with orig tarball) for
released kernels.

This is a minimal conversion to the new formats. The immediate benefit
is ability to use xz compression for the source tarballs, GPG verified
upstream tarballs, and simplify kernel patching for those that are
rebuilding Ubuntu kernels.

Once this is applied we will then be able to further simplify our
packaging by collapsing debian.* directories under debian dir, and
significantly reducing - if not eliminating our reconstruct scripts.
