  Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons.  They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code.  In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)
