Fix the (broken) URL for the following items:
- Elephant File system:
This seems to have moved out, and I cannot seem to find it anywhere through Google'ing and contacting the author seem to have failed. Instead use the CiteSeer URL (to the publication).
- GLOBAL:
The GLOBAL source tagging system is now a GNU project and thus moved out, so use the right URL to the GNU project's web site.
Two more URLs seem to stay broken, including WAFS, and the
SoundBlaster AWE32/64 page; no suitable alternative could be
found.
