XMI updates

[Jon M. Taylor]

        LibXMI has been modified to handle the new GGI DL entrypoint
system, and the lockup problems have (hopefully) been fixed as well.  At
least over here, demo.c runs on the X and fbdev targets without problems
now.  Everyone who is using LibXMI, please download and test.
