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.
