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

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.

- introduced common/jpeg/{configure.ac,Makefile.am}
- removed autogenerated stuff (jconfig.h, configure, config.guess, config.sub, jconfig.h, install-sh)
- minor macros changes in jchuff.c, jcphuff.c, jmorecfg.h (same with configure produced macros)
