Boris Zbarsky 1540774b0c Bug 1157898 part 1. Make code of the form "return rv.ErrorCode();" where rv is an ErrorResult use StealNSResult instead. r=peterv 
This patch was generated with the following command:

  find . -name "*.h" -o -name "*.cpp" | xargs perl -pi -e 's/return ([a-zA-Z0-9]+)\.ErrorCode\(\);/return \1.StealNSResult();/'
