libdrm: add mode setting files
Add mode setting files to libdrm, including xf86drmMode.* and the new drm_mode.h header. Also add a couple of tests to sanity check the kernel interfaces and update code to support them.

+ * blue background should be painted on the monitor attached to the specified
+ * connector after the selected mode is set.
