Windows: Implementing C++ DEF parser

C++ DEF parser can generating a DEF file from a object file, which can
be used to export symbols during linking DLL on Windows.

This parser is based on an implementation in CMake
See https://github.com/Kitware/CMake/blob/master/Source/bindexplib.cxx
A few changes has been made to make it work better.

Usage: output_deffile dllname [objfile ...] [input_deffile ...] [@paramfile ...]

output_deffile: the output DEF file

dllname: the DLL name this DEF file is used for, if dllname is not empty
         string (eg. ""), def_parser writes an 'LIBRARY <dllname>' entry
         into DEF file.

objfile: a object file, def_parser parses this file to find symbols,
         then merges them into final result.
         Can apppear multiple times.

input_deffile: an existing def file, def_parser merges all symbols in this file.
               Can appear multiple times.

@paramfile: a parameter file that can contain objfile and input_deffile
            Can appear multiple time.
