Introduces a new (optional) dependency: libdrm. The DrmBackend currently supports finding the first connected output. It can create shared memory buffers which are used by SceneQPainter to do double buffered rendering. There is still lots to do, the following things are not yet working: * multiple outputs * page flip * OpenGL (through gbm) * restoring mode setting to start value
