  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.
