util: add a script to auto-generate a drirc infrascture per driver
Instead of having each driver define : - options through DRI_CONF_OPT_* macros - call driQueryOption*() to parse those options - define all the variables to old those options' values We add one script to do it all for you. All you have to do now is list all the options you want in a python file.
