Symbol file should contain module GUID at beginning (#66). r=bryner
- The dumped symbol format now begins with a MODULE line identifying the uuid, age, and name of the source pdb file. - The processor ignores MODULE lines, but they are useful in figuring out how to index symbol files in a symbol store. - dump_syms and symupload now both accept either a pdb or exe/dll and will read the pdb regardless. - Figured out that MSSS always represents a module's age in pathnames in hexadecimal, and updated SimpleSymbolSupplier to match. http://groups.google.com/group/airbag-dev/browse_thread/thread/572108d6567edd58 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@59 4c0a9323-5329-0410-9bdc-e9ce6186880e
