  Fixed bug #37076: TIMESTAMP/DATETIME/DATE values are not
                    replicated correctly between machines with
                    mixed endiannes
  
  pack and unpack virtual methods have been overloaded for
  Field_timestamp (TIMESTAMP domain), Field_datetime (DATETIME
  domain) and Field_date (DATE domain) classes to replicate data
  between platforms with different endiannes in a correct way
  like in Field_long and Field_longlong classes.
  
  Common code have been moved to private handle_int32 and 
  handle_int64 private methods.
