DRC ef9a4e05ba Integrate a slightly modified version of Mozilla's patch for precomputing the bit-counting LUT. This is useful if the table needs to be shared among multiple processes, although the primary reason for doing that is reduced footprint on mobile devices, which are probably already covered by the clz intrinsic code.

DRC 0cfc4c17b7 Use clz/bsr instructions on ARM for bit counting rather than the lookup table (reduces memory footprint and can improve performance in some cases.)

DRC a6ef282a49 Some of the IJG headers say "Modified by", so clarify that our "Modifications" are not referring to these.

DRC ba923a8529 Fix I/O suspension. This little nugget of code was introduced in r30 as part of an early attempt to make buffered I/O work with the optimized Huffman codec. Ultimately, r32 reverted a lot of that mess and introduced much of the logic we now use, rendering this code unnecessary, but it was never reverted because it only causes problems when I/O suspension is used, and apparently no one has tried to do that with libjpeg-turbo until now.

DRC 6bb57b7219 Re-factor and re-license under the libjpeg BSD-style license. Justification: the accelerated Huffman encoding optimizations in libjpeg-turbo were all developed by me as an independent developer. The structure of the inline Huffman encoding macros was originally borrowed from similar routines in the TurboJPEG/mediaLib codec, which is part of VirtualGL and TurboVNC. Thus, although the code for these macros was not copied verbatim, they were still thought to be a derivative work of TurboJPEG/mediaLib, and I assigned the copyright and license from TurboJPEG/mediaLib to them. I have re-written these routines from first principles by breaking down the libjpeg out-of-line routines. Although the new code bears algorithmic similarities to the TurboJPEG/mediaLib macros, it can now clearly be shown to be derived from the out-of-line routines and thus, in my opinion, it can no longer be considered a derivative of TurboJPEG/mediaLib. -- DRC

DRC dae4474117 Unfortunately, the previous enhancements made an invalid assumption about the code sizes, which caused "DCT out of range" errors in the decoder. Was able to fix 64-bit without losing any performance, but unfortunately had to revert 32-bit back to its previous behavior for now.
