Make SourceLineResolver use RangeMap (#13). r=bryner

- Eliminate MemAddrMap from source_line_resolver.cc and adapt it to use
   RangeMap, also used by minidump.cc.
 - RangeMap operates on both a base address and a size, where MemAddrMap
   only used a base address, so the dumped symbol file format is modified
   to include size information.  dump_syms produces these files and
   SourceLineResolver consumes them.
 - Provide updated test data conforming to the new dumped symbol format.
