004427c071 Add a set of undocumented environment variables and Java system properties that allow compression features of libjpeg that are not normally exposed in the TurboJPEG API to be enabled. These features are not normally exposed because, for the most part, they aren't "turbo" features, but it is still useful to be able to benchmark them without modifying the code.

3d037a5c72 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

66245aa735 libjpeg-turbo has never supported non-ANSI compilers, so get rid of the crufty SIZEOF() macro. It was not being used consistently anyhow, so it would not have been possible to build prior releases of libjpeg-turbo using the broken compilers for which that macro was designed.

1aa56251a9 Get rid of the HAVE_PROTOTYPES configuration option, as well as the related JMETHOD and JPP macros. libjpeg-turbo has never supported compilers that don't handle prototypes. Doing so requires ansi2knr, which isn't even supported in the IJG code anymore.

0d141f4844 For now, punt on trying to support fancy upsampling in tjDecodeYUV(). Fancy upsampling requires context rows and other refinements, which are difficult to implement correctly with the algorithm we're using. Longer-term, supporting fancy upsampling would probably require using the main buffer that libjpeg allocates.

c33bc1dab0 When tjDecodeYUV() is used with a "fresh" decompressor instance (one that hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error.

693f4a5600 Fix an issue that prevented tjEncodeYUV2() 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 tjEncodeYUV2() 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.)
