// symupload.mm: 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"
//  os: the operating system that the module was built for
//  cpu: the CPU that the module was built for (x86 or ppc)
//  symbol_file: the contents of the breakpad-format symbol file
