debian/ubuntu packaging, v2

See #93, #121

Added

* package build rules to debian/

* install rules to makefiles

* guides on packaging and deb-repository creation

Several files in /debian directory still contain stub info (READMEs for the most part). Some meaningful content can be added there or those files can be safely removed for the next release.

In /src/doc/packaging.md doc mentioned current forks for libraries packaged. We probably need to push those somewhere and update document accordingly. Any suggestions here?
