Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
Update some files in GDB that were accidently left with a GPL v2
copyright header.
Update some files where the copyright notice still provides the
old contact info, using the approach for providing the FSF's contact
info.
