Breakpad: Extract parsing code into a separate file Summary: This centralizes parsing of breakpad records, which was previously spread out over ObjectFileBreakpad and SymbolFileBreakpad. For each record type X there is a separate breakpad::XRecord class, and an associated parse function. The classes just store the information in the breakpad records in a more accessible form. It is up to the users to determine what to do with that data. This separation also made it possible to write some targeted tests for the parsing code, which was previously unaccessible, so I write a couple of those too.

Open ELF core dumps with more than 64K sections Summary: Problem: There are three filelds in the ELF header - e_phnum, e_shnum, and e_shstrndx - that could be bigger than 64K and therefore do not fit in 16 bits reserved for them in the header. If this happens, pretty often there is a special section at index 0 which contains their real values for these fields in the section header in the fields sh_info, sh_size, and sh_link respectively. Fix: - Rename original fields in the header declaration. We want to have them around just in case. - Reintroduce these fields as 32-bit members at the end of the header. By default they are initialized from the header in Parse() method. - In Parse(), detect the situation when the header might have been extended into section info #0 and try to read it from the same data source. - ObjectFileELF::GetModuleSpecifications accesses some of these fields but the original parse uses too small data source. Re-parse the header if necessary using bigger data source. - ProcessElfCore::CreateInstance uses header with potentially sentinel values, but it does not access these fields, so a comment here is enough.
