gl: Add support for Vivante EGL FB windowing system
This is very similar to how dispmanx on the Raspberry Pi works. Based on a patch by Haihua Hu <b55597@freescale.com> from https://github.com/Freescale/meta-freescale/tree/master/recipes-multimedia/gstreamer/gstreamer1.0-plugins-bad https://bugzilla.gnome.org/show_bug.cgi?id=778825
