Extend the YUV decode functionality to the TurboJPEG Java API, and port the TJUnitTest modifications that treat YUV encoding/decoding as an intermediate step of the JPEG compression/decompression pipeline rather than a separate test case; Add the ability to encode YUV images from an arbitrary position in a large image buffer; Significantly refactor the handling of YUV images; numerous doc tweaks; other Java API cleanup and usability improvements

Streamline the BufferedImage functionality in the compressor so that it works the same way as compressing a "normal" image, and deprecate the old BufferedImage methods and other redundant methods. Eliminate the use of deprecated features in the test programs.

Remove benchmarks. They were originally intended as a way of measuring overhead for small compress/decompress operations, but using TJBench with a small image is a better way to accomplish that.

Fix an issue that prevented tjEncodeYUV3() and TJCompressor.encodeYUV() from working properly if the source image was very tiny. Basically, jpeg_start_compress() was attempting to write the JPEG headers, which was overrunning the YUV buffer. This patch removes the call to jpeg_start_compress() in tjEncodeYUV3() and replaces it with calls to the individual routines that are necessary to initialize the color converter and downsampler. TJUnitTest has also been modified to test for this condition (the buffer size regression test now works in YUV mode.)
