Prefer glxvisuals with stencil buffer for default visuals
The first fbconfig which has a depthbuffer > 0 and doublebuf is choosen when associating fbconfigs with the visuals, indepenent of stencil bits. This happens to work ok on intel as there all fbconfigs with a depthbuffer > 0 also have stencil bits. This patch fixes this by first trying to get a fbconfig for default X visuals with both stencilbuf, depthbuf and doublebuffering, and if that fails fallback to trying to get one with only a depthbuf and doublebuffering.
