[Mesa-dev] [PATCH] vulkan/wsi/x11: add support to detect if we can support rendering

From: Dave Airlie <airlied at redhat.com>
This adds support to radv_GetPhysicalDeviceXlibPresentationSupportKHR
and radv_GetPhysicalDeviceXcbPresentationSupportKHR to check if the
local device file descriptor is compatible with the descriptor
retrieved from the X server via DRI3.
This will stop radv binding to an X server until we have prime
support in place. Hopefully apps use this API before trying
to render things.
