GstVaapiTexture is a generic abstraction that could be moved to the core libgstvaapi library. While doing this, no extra dependency needs to be added. This means that a GstVaapitextureClass is now available for any specific code that needs to be added, e.g. creation of the underlying GL texture objects, or backend dependent ways to upload a surface to the texture object. Generic OpenGL data types (GLuint, GLenum) are also replaced with a plain guint. https://bugzilla.gnome.org/show_bug.cgi?id=736715
