Bug #53493 : add_to_status does not handle the longlong fields in STATUS_VAR

Browse Source 
bytes_received/bytes_sent are ulonglong so they cannot be handled by the 
ulong handling code in add_to_status/add_diff_to_status().

Fixed by adding code to handle these two variables in 
add_to_status()/add_diff_to_status() and making sure they are not a subject
to the ulong handling code.
