fcl-db: datapacketreader: change of interface methods. Pass reference to TCustomBufDataset only once in constructor of TDatapacketReader, so instance of datapacketreader will know about BufDataset for which it was created and there is no need to pass this reference on "every" call to methods of TDataPacketReader. It brings simplicity and more flexibility IMHO.
DO NOT BACKPORT THIS TO 2.6.3
