  Pi: Workaround conflicting EGL headers for open/closed source

- when MMAL is enabled, the Broadcom specific EGL headers are picked up
from (typically) /opt/vc/include
- this does not contain sundry extension definitions required when
building for open source OpenGL support.
- so add an extra header and define what is missing...

  V4L2 Codecs: Add DRM PRIME direct rendering support

- tested on a Pi 3
- significant performance improvement but far from perfect and still
doesn't feel as fast as it should be.
- returned texture is RGB so limited colourspace support and no
deinterlacing (as noted however, the VC4 driver does not return
interlacing flags - also appears to be an issue on other drivers)
- the DRM PRIME code should be generic and not tied to V4L2 - it could
in theory be used to display VAAPI frames.
- configure/configuration may need a little more work with respect to
libdrm
