Looks like a good bit of savings. A couple of comments:

 * I don't think we need to publish new API here.

 * It would be more efficient (and less confusing) if FcCharSetMerge
   just did the union in-line -- it need only walk the new charset and
   not look at each page of the existing one. Plus, that leaves all of
   the other charset functions unchanged.
