 // symupload.cc: Upload a symbol file to a HTTP server.  The upload is sent as
 // a multipart/form-data POST request with the following parameters:
 //  code_file: the basename of the module, e.g. "app"
 //  debug_file: the basename of the debugging file, e.g. "app"
 //  debug_identifier: the debug file's identifier, usually consisting of
 //                    the guid and age embedded in the pdb, e.g.
 //                    "11111111BBBB3333DDDD555555555555F"
 //  version: the file version of the module, e.g. "1.2.3.4"
 //  os: the operating system that the module was built for
 //  cpu: the CPU that the module was built for
 //  symbol_file: the contents of the breakpad-format symbol file
