Dynamically change source package to quilt format
Dynamically change source package to quilt format

In order to have source packages that match the binary packages and
yet still only store the source files only once we need to use
the quilt format. This change creates a *.orig.tar.xz file from the
source tree and then create the real source package using the
quilt format.
