  Format copyright headers more consistently
  
  The IJG convention is to format copyright notices as:
  
  Copyright (C) YYYY, Owner.
  
  We try to maintain this convention for any code that is part of the
  libjpeg API library (with the exception of preserving the copyright
  notices from Cendio's code verbatim, since those predate
  libjpeg-turbo.)
  
  Note that the phrase "All Rights Reserved" is no longer necessary, since
  all Buenos Aires Convention signatories signed onto the Berne Convention
  in 2000.  However, our convention is to retain this phrase for any files
  that have a self-contained copyright header but to leave it off of any
  files that refer to another file for conditions of distribution and use.
  For instance, all of the non-SIMD files in the libjpeg API library refer
  to README.ijg, and the copyright message in that file contains "All
  Rights Reserved", so it is unnecessary to add it to the individual
  files.
  
  The TurboJPEG code retains my preferred formatting convention for
  copyright notices, which is based on that of VirtualGL (where the
  TurboJPEG API originated.)
