Re-factor and re-license under the libjpeg BSD-style license. Justification: the accelerated Huffman decoding optimizations in libjpeg-turbo were all developed by me as an independent developer. The structure of the inline Huffman decoding 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

The previous attempt to handle unexpected markers in the data stream caused breakage in applications that attempted to set bytes_in_buffer to a larger value than the actual size of the JPEG image. The latter behavior was causing the fast decoder to be used for the last MCU in the image under certain circumstances, and this sometimes caused the EOI marker to be encountered by the fast decoder, which was treating it as an "unexpected" marker and throwing an error. Now, the fast decoder simply hands off the decoding of the block to the slow decoder if any marker is encountered.

Fix data corruption issues when decompressing large JPEG images and/or using buffered I/O. Specifically, decode_mcu_fast() can potentially process more than 1 MCU, so make sure there is enough space in the buffer to accommodate this case. Otherwise, the buffer pointer goes negative, and bad mojo ensues. Also, the fast decoder's method of handling unread markers doesn't make libjpeg's restart handler happy, so disable fast decode when restarts are used.
