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.)

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.
