Integrate COMPOSITEWRAP branch including composite wrapper. This code still

has several issues, including:
- CopyWindow and PaintWindow wrappers missing (will be done soon)
- Some segfaults seen in the Render wrappers.
- Xprt server build breaks with Composite.
- DDXs must be recompiled for Composite due to VisualRec size change.
- Composite bugs pointed out by Deron Johnson in email.
Also, reorder XFixes initialization according to comments by Keith which
    are also in xserver CVS.
