Up to [Development] / xfs-linux-nodel

Encumbrance review done.
Add copyright and license words consistent with GPL.
Refer to http://fsg.melbourne.sgi.com/reviews/ for details.

There is a slight change in the license terms and conditions words
to go with the copyrights, so most of the files are not getting
new GPL's, just updated versions ... but there are 20-30 more files
here as well.
