Extend YUVImage class to allow reuse of the same buffer with different metadata; port TJBench changes that treat YUV encoding/decoding as an intermediate step of the JPEG compression/decompression pipeline rather than a separate test case; add YUV encode/decode tests to the Java version of tjbenchtest

+# NOTE: The combination of tjEncodeYUV*() and tjCompressFromYUV*() does not
+# always produce bitwise-identical results to tjCompress*() if subsampling is
+# enabled.  In both cases, if the image width or height are not evenly
+# divisible by the MCU width/height, then the bottom and/or right edge are
+# expanded.  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.  This latter
+# phenomenon is not yet fully understood but is also believed to be some sort
+# of round-off error.)
