8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.
