Add initial support for EGL to libgstvaapi core library. The target display server and the desired OpenGL API can be programmatically selected at run-time. A comprehensive set of EGL utilities are provided to support those dynamic selection needs, but also most importantly to ensure that the GL command stream is executed from within a single thread. https://bugzilla.gnome.org/show_bug.cgi?id=743846
