Fill in __glXDisp_GetCompressedTexImageARB and

GL_ARB_texture_compression. With this extension (and the related
compression extensions), the server-side GLX supports all of the
protocol for GL 1.4. w00t!
The bad news is that this has received only minimal testing, and Mesa
does not contain any good tests for GL_ARB_texture_compression.
