XQuartz: GL: Make many more fbconfigs and visuals available for the 1.5 branch.
Use a __GLXconfig linked list struct to store the configurations for the
fbconfigs and visuals in a pGlxScreen.
Also, remove the __GLXvisualConfig/GlxSetVisualConfigs code that isn't used
anymore. There is more code we can remove later, but I want to do that in
separate commits.
