Module API (#32). r=waylonis, bryner

Browse source 
- 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.
