ce6891f048 If we have transformed a 4:2:2 or 4:4:0 image in any way that transposes the horizontal and vertical dimensions, then we need to inform the decompression function that the subsampling type has changed. Otherwise, tjDecodeYUV() will not produce correct results.

95e4cb2060 Since we now have a complete set of YUV functions, TJBench can be greatly simplified. It now tests YUV encoding/decoding as an intermediate step of JPEG compression/decompression, which eliminates the need for a separate YUV mode. Several other things have been streamlined in the process.

d4b453c26e Back-port the -subsamp option from 1.4 rather than use the hackish approach of replacing 4:2:2 with 4:4:0. This has the added advantage of allowing the user to test only a specific level of subsampling.

c6501f7f5f Add the ability to test scaling when decompressing to YUV; compression from YUV to JPEG; and YUV padding. Replace clunky -411 and -440 parameters with a -subsamp parameter that allows any of the subsampling options to be tested in isolation.

07e982d9b4 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.

c45653e471 Fix a couple of issues with return value checking. JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.
