Add basic support for CI test execution

Add basic support for executing continuous integration (CI) tests on
RHEL6, RHEL7, Fedora 20, Fedora Rawhide and Debian Testing.

This adds two front-end scripts which can be executed either locally by
developers, or on a CI server: contrib/ci/run and contrib/ci/clean.
The first one will run the tests and the second will wipe out the
artifacts.

See contrib/ci/README.md for further details.
