- Introduces a standard API for dealing with modules. MinidumpModule is now a concrete implementation of this API. Code may interact with single modules using the CodeModule interface, and collections of modules using its container, the CodeModules interface. - CodeModule is used directly by SymbolSupplier implementations and SourceLineResolver. Reliance on the specific implementation in MinidumpModule has been eliminated. - Module lists are now added to ProcessState objects. Module references in each stack frame are now pointers to objects in these module lists. - The sample minidump_stackwalk tool prints the module list after printing all threads' stacks. http://groups.google.com/group/airbag-dev/browse_frm/thread/a9c0550edde54cf8 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@74 4c0a9323-5329-0410-9bdc-e9ce6186880e
