driCheckDriDdxDrmVersion uses a function that is not available to

drivers when DRI_NEW_INTERFACE_ONLY is defined.  #ifndef it away in
that situation.

Add a new function, driCheckDriDdxDrmVersion2, that is passed in the
version information that is already supplied to __driCreateNewScreen.
Part of the reason that information is supplied to
__driCreateNewScreen is so that the driver doesn't have to make those
calls to get it!

Modify all drivers that support the new interface to use the new
function instead of the old.  As soon as all drivers support the new
interface, driCheckDriDdxDrmVersion can be removed.
