commit 60b2487e0f0454a0f9db1f645df38f4183e010bc

    CVE-2016-1234: glob: Do not copy d_name field of struct dirent [BZ #19779]

    Instead, we store the data we need from the return value of
    readdir in an object of the new type struct readdir_result.
    This type is independent of the layout of struct dirent.

    (cherry picked from commit 5171f3079f2cc53e0548fc4967361f4d1ce9d7ea)
    (cherry picked from commit c87db3fcbdf890990b44d956621763538c878cd3)
