  Add a meta-script to run code generators.
  
  This script calls all the various GL and back-end python scripts to
  generate our internal format tables and entry points, etc. It uses
  a GYP-like scheme of inputs/outputs to check modified time before
  running the generators. It also will automatically call 'git cl
  format' if any generator was called.
  
  Also updates the copyright in a couple of touched files.
