This is a major update coming all at once from master-next branch
master-next branch was started with --orphan option which is basically a new
branch without history.
The major changes are:
- repackaging
- cleanup the directory tree
- rewritte setup.py to allow install from deb file or pypi (pip install)
- add a Makefile to make things (like building a deb) easier
- review all debian files
