    roaring.[ch]: Add attribution and licensing information
    
    OS distributions that take copyright and licensing seriously will tend
    to become concerned about source files that appear to come from a
    third party and do not come with copyright/licensing information,
    and stating that these files are modified is required by clause 4(b)
    of the Apache license.
