Backporting Sumo to Pyro-based OE-port

I forked OpenEmbedded in June 2017, when the Pyro version was released. My fork, named oe-qky-src, is on GitHub, and is very different from the mainline OE project, so I can't easily sync with it.

The latest release of OE is Sumo, and I am working around the sync problem by gradually backporting Sumo recipes. To that end, I created a "sumo" layer, and have made some commits (June 22, 2018):

In particular, meta/recipes-graphics and meta-oe/recipes-graphics have been backported, which includes Xorg and mesa.
