Jason McDonald 5e801e2793 Remove "All rights reserved" line from license headers. 
As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.
