[$] Advances in Mesa continuous integration

Continuous integration (CI) has become increasingly prevalent in open-sourceprojects over the last few years. Intel has been active in building CIsystems for graphics, both for the kernelside and for the Mesa-baseduser-space side of the equation. Mark Janes and Clayton Craft gave apresentation on Intel's Mesa CI system at the 2018 X.Org Developers Conference (XDC), which was held in A Coruna, Spain in late September. The Mesa CI system is one of the earliest successful CI initiatives in opensource that he knows of, Janes said. It is a core component of Mesa development,especially at Intel.
