[Bastien Nocera <hadess src gnome org>]

commit 54476e06f868b37298a261a01c07414fd272e8a5
Author: Iñigo Martínez <inigomartinez gmail com>

    build: Use template files for enums generation
    
    The data contents for the enum related files were stored in the
    build files.
    
    This patch moves this information to template files to be used
    along glib-mkenums.
