kms: Add first version of "baremetal" backend for EGL on KMS To start with this backend only supports creating a single CoglOnscreen framebuffer and will automatically set is up to display fullscreen on the first suitable crtc it can find. To compile this backend - get some dribbly black candles, sacrifice a goat and configure with: --enable-kms-egl-platform Note: There is currently a problem with using GLES2 with this winsys so you need to run with EGL_DRIVER=gl Note: If you have problems with mesa crashing in XCB during eglInitialize then you may need to explicitly run with EGL_PLATFORM=gbm Reviewed-by: Robert Bragg <robert@linux.intel.com>
