Android emulator opengl - unit test host side renderer

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.
