[commit 2/3] use gnulib's update-copyright script to update copyright years

Joel Brobecker
2012-01-04T08:20:50Z

This patch now retires the old copyright.sh script which was using
emacs to perform the copyright update. It also completely rewrite
copyright.py to call update-copyright with the appropriate list
of files.

In addition to calling update-copyright, the new script also performs
a sanity-check on all the files that update-copyright could not update,
and sees whether the file might contain a copyright notice that
the script could not decipher.

gdb/ChangeLog:

* copyright.sh: Delete.
* copyright.py: Rewrite.

Checked in.
