Refactored YUVImage Java class so that it supports both unified YUV image buffers as well as separate YUV image planes; modified the JNI functions accordingly and added new helper functions to the TurboJPEG C API (tjPlaneWidth(), tjPlaneHeight(), tjPlaneSizeYUV()) to facilitate those modifications; changed potentially confusing "component width" and "component height" terms to "plane width" and "plane height" and modified variable names in turbojpeg.c to reflect this; numerous other documentation tweaks

Clean up and consolidate notes regarding the YUV image format. This also corrects a factual error regarding the padding of the luminance plane-- because we now support 4:1:1, the component width is not necessarily padded to the nearest multiple of 2 if horizontal subsampling is used.

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

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.

Per the conventions of the image compression and digital video communities, use "YCbCr" to describe the JPEG colorspace and "YUV" to describe an image format consisting of Y, Cb, and Cr planes (this partially reverts r960.)

Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

Slight refactor to put ScalingFactor into its own class (mainly because the $ in the class name was wreaking havoc on the build scripts, but also to add a few convenience methods to it) and to create a separate loader class so we can provide a .jar file with the MinGW distribution that loads the correct DLL
