symupload parameters don't match processor expectations (#91). r=bryner

- Interface change: the "guid" and "age" parameters supplied to a symbol
   server by symupload have been merged into "debug_identifier".  Some
   other parameters have had their names changed.  Additional code_file,
   os, and cpu parameters have been added.
 - Interface change: the format of the MODULE line at the top of dumped .sym
   files has changed slightly.  The fields used for uuid and age have
   merged into a debug_identifier-type field.
 - debug_identifier is formatted the same way as CodeModule::debug_identifier
   for ease of server-side processing.
