    Cleanup after meson port.
    
    * As the build is always out-of-source, we don't need gitignores
      everywhere. I added sane defaults in the top-level gitignore.
    
    * Remove auto-generated sources (*.cl.h) as they are *not* used at build
      time (the ones in the build directory are)
