Subject: Before calling _mesa_create_context(), initialize a dd_function_table
 struct by calling _mesa_init_driver_functions() and then plugging in the
 driver- specific functions. In particular, make sure
 ctx->Driver.NewTextureObject points to the appropriate driver function so
 that _all_ texture objects are augmented with the driver-specific data. Put
 in a bunch of assertions in the texture-related driver functions that
 texObj->DriverData is valid.  Remove old dead code in near future.
