  Format preprocessor macros more consistently
  
  Within the libjpeg API code, it seems to be more the convention than not
  to separate the macro name and value by two or more spaces, which
  improves general readability.  Making this consistent across all of
  libjpeg-turbo is less about my individual preferences and more about
  making it easy to automatically detect variations from our chosen
  formatting convention.  I intend to release the script I'm using to
  validate this stuff, once it matures and stabilizes a bit.
