fix_stack_using_bpsyms.py locates a .sym file based on file name only, not uuid or full path, which causes a failure if a duplicate leaf file name is introduced. This patch introduces a small utility program on mac and linux to extract a breakpad guid from a shared library or executable to identify the correct symbol file when this ambiguity occurs. A subsequent commit implements this for windows. --HG-- extra : commitid : 2O7REfHuDus
