Log Message:

fix some issues with freeing Xft/fontconfig resources.

Remaining problem: 
  
  - XftFontsetDestroy() calls free() for each XftPattern stored in the
    Fontset.  XftPatterns created by MAKE-XFT-PATTERN get their own
    finalizer, thus if added to the fontset, there might be two calls
    to free() for that object.  That needs fixing.
