TurboJPEG: Add lossless JPEG detection capability Add a new TurboJPEG C API function (tjDecompressHeader4()) and Java API method (TJDecompressor.getFlags()) that return the bitwise OR of any flags that are relevant to the JPEG image being decompressed (currently TJFLAG_PROGRESSIVE, TJFLAG_ARITHMETIC, TJFLAG_LOSSLESS, and their Java equivalents.) This allows a calling program to determine whether the image being decompressed is a lossless JPEG image, which means that the decompression scaling feature will not be available and that a full-sized destination buffer should be allocated. More specifically, this fixes a buffer overrun in TJBench, TJExample, and the decompress* fuzz targets that occurred when attempting (in vain) to decompress a lossless JPEG image with decompression scaling enabled.

However, the libjpeg code performs this expansion prior to # downsampling, and TurboJPEG performs it in tjCompressFromYUV*(), which is # after downsampling. Thus, the two will agree only if the width/height along # each downsampled dimension is an odd number or is evenly divisible by the MCU # width/height. This disagreement basically amounts to a round-off error, but # there is no easy way around it, so for now, we just test the only image that # works. (NOTE: nightshot_iso_100 does not suffer from the above issue, but # it suffers from an unrelated problem whereby the combination of # tjDecompressToYUV*() and tjDecodeYUV*() do not produce bitwise-identical # results to tjDecompress*() if decompression scaling is enabled.
