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
