Bug 1156: GBM: Bring up incl GL rendering (TODO: GBM working page flip / sync)

- EGLSurface: Factor out 'eglCreate[Platform]WindowSurface'

NEWT egl.gbm.WindowDriver
-- Properly use GBM fourcc format and use as visualID
   for GBM surface creation and EGL config selection
-- Create eglSurface within this class
-- Hook up GBM/DRM page flip (not working yet, no visible artifacts - no swap)

- ProxySurfaceImpl.surfaceSwap() call upstreamSurface's implementation if available

TODO: 'Permission denied' calling:
- drmSetMaster (optional)
- drmModeSetCrtc
- drmModePageFlip
