Eric Anholt 6ed08949af Move libcw setup to the only renderer requiring it (XAA). 
Additionally, protect libcw setup behind checks for Render, to avoid
segfaulting if Render isn't available (xnest).

The previous setup was an ABI-preserving dance, which is better nuked now.
Now, anything that needs libcw must explicitly initialize it, and
miDisableCompositeWrapper (previously only called by EXA and presumably binary
drivers) is gone.
