Eric Anholt dc0354104c Move EXA implementation up to the top level and remove its XFree86
dependencies. It was nearly abstract enough already to be used by
    multiple DDXes. This will be useful for EXA development through
    providing a fake acceleration implementation within Xephyr, so that
    testing can be done on new EXA code without worrying about buggy
    drivers.
