In order to create the set of available extensions, we have to know if
direct-rendering is possible on a given screen. It is not possible to determine this by just looking at driDisplay.private in the display structure. However, it is possible to determine this by looking at driScreen.private in the screen structure. This field is only non-NULL if a DRI driver has been successfully loaded and bootstrapped. Once we get to that point, we know that direct-rendering is at least theoretically possible. This fixes bugzilla #2875.
