Xwayland will eventually need the current client in dri3_open. Simply changing that API is not an option though as other drivers that implement DRI3 will not have a matching function signature and will crash when called. Add a new dri3_open_client function pointer and bump DRI3_SCREEN_INFO_VERSION so that drivers can be aware of the new function which will be used in preference to the old function when available.
