Use a more robust method of obtaining the build timestamp on Windows. 'wmic os get LocalDateTime' will always return the timestamp in the format we want (YYYYMMDD), whereas date /t is sensitive to locale. If wmic fails, then we fall back to using date /t, even though this means that the BUILD variable will end up in the incorrect format on some systems.

Add a Java version of TJBench and extend the TurboJPEG Java API to support it (this involved adding a polymorphic method in TJCompressor that accepts x and y offsets into a larger buffer, similar to the previous modification that had been done to TJDecompressor.)

Added flags to the TurboJPEG API that allow the caller to force the use of either the fast or the accurate DCT/IDCT algorithms in the underlying codec.

More recent versions of autoconf add -traditional-cpp to the CPP flags, which causes jsimdcfg.inc.h to not preprocess correctly unless we expand all of the instances of the #definev macro.

Later versions of autoconf (specifically, the one shipped with Xcode 4.3) default to building x86-64, so it is necessary to override the host_alias to get a 32-bit build.

Fixed regression caused by a bug in the 32-bit strict memory access code in jdmrgss2.asm (contributed by Chromium to stop valgrind from whining whenever the output buffer size was not evenly divisible by 16 bytes.) On Linux/x86, this regression caused incorrect pixels on the right-hand side of images whose rows were not 16-byte aligned, whenever fancy upsampling was used and when decompressing to a 32-bit (RGBX, etc.) buffer.

Emulate colorspace extensions if they are not present in the libjpeg API. This allows the TurboJPEG wrapper to be used with libjpeg rather than libjpeg-turbo. Not useful within the context of our project, but other projects prefer to include the TurboJPEG wrapper in-tree, and this allows them to be linked against either libjpeg-turbo or libjpeg.
