[Piglit] [PATCH] glx: New test for GLX_EXT_no_config_context

[Adam Jackson]

Create a no-config context, create one window of every visual, make it
current against each of them. This is a bit of a touch test right now,
this should be extended to create each kind of drawable for each config
and to verify some rendering.
