This adds 'ut_renderer' - a host side unit test renderer. ut_renderer is used to take a command stream over a socket connection and render it into an opengl window. The renderer uses the GLESv1_dec decoder library and the ut_rendercontrol api to parse the command stream. The ut_renderer uses an external (plug-in) opengl impelementation.
