Fix MSan use-of-uninitialized-value error ... introduced by 42825b68d570fb07fe820ac62ad91017e61e9a25. In fact, fault-tolerant multi-scan block smoothing cannot currently be used with the arithmetic decoder, because that decoder doesn't have any way of distinguishing a normal end of scan from an unexpected end of scan. Thus, this commit also modifies the change log to reset the expectations regarding the scope of the fault-tolerant multi-scan block smoothing feature. If, at some point in the future, the arithmetic decoder can be modified to detect an unexpected end of scan, then one would need only set entropy->pub.insufficient_data = TRUE when the arithmetic decoder encounters an unexpected end of scan in order to make fault-tolerant block smoothing work properly with that decoder.
