[PATCH 09/12] drm/vmwgfx: Allow checking for gl43 contexts

From: Zack Rusin <zackr at vmware.com>

To make sure we're running on top of hardware that can support
GL4.3 we need to add a way of querying for those capabilities.
DRM_VMW_PARAM_GL43 allows userspace to check for presence of
GL4.3 capable contexts.
