Subject: [PATCH] [GLX/SWrast] Make GLX with SWrast enabled work on older Xservers.
Patch-mainline: To be upstreamed

Older Xservers don't offer a set of configs/visuals that is compatible
with DRI. If no visuals or configs are found let driswCreateScreen()
fail so that the next fallback path is take.
