This changes the way we name distros in order to be compatible with the
current repository layout

On the first try of fetching contrib packages, all downloads will start
at the same time. This should speed up the builds significantly.

If it fails, we will try again but not all at the same time. So the
errors should still be legible.

This imports some of the changes made in the official Debian packaging
repository: https://anonscm.debian.org/cgit/pkg-voip/ring.git

- Don't run containers in interactive mode, which would require a TTY

- Build LRC with Debug symbols

- Build with V=1 to allow parsing logs

- Reorganize dependencies

- Try fetch-all three times before giving up

- Removed ubuntu15.04 references

This moves the official Debian packaging into ring-project. Jenkins
should now be able to run packaging jobs and publish packages. It
should also make it easy to add a `verify` check on Jenkins to test
packaging patches.

This will make it much easier to work on packaging issues because the
build environment is now reproductible on any machine.

The patch adds Makefile targets to create packages such as:
 - package-all
 - package-<DISTRO>

Builds are all done inside Docker containers and it is possible to
build many at a time with the `package-all` target.

To debug a build, use `package-<DISTRO>-interactive` to obtain a shell
inside a container, ready to launch a build.

This script comes from the jenkins jobs that publishes release tarballs
on https://dl.ring.cx/ring-release/tarballs/. It is best to make it
available in the source so that people can see how we generate our
tarballs and maybe use it for other purposes.
