    Update AM_PROG_LIBTOOL to AC_PROG_LIBTOOL in configure.ac (#734718)
    
    AM_PROG_LIBTOOL is an old name and alias for AC_PROG_LIBTOOL.  Update.
    
    NOTE:
    In turn AC_PROG_LIBTOOL is an old name and alias for LT_INIT, but
    CentOS 5.x with libtool 1.5.22 doesn't have LT_INIT defined in
    /usr/share/aclocal/libtool.m4 serial 48, only AC_PROG_LIBTOOL and
    AM_PROG_LIBTOOL.  Therefore only update to AC_PROG_LIBTOOL and not
    LT_INIT while CentOS 5.x is supported.
    
    Bug #734718 - Update Autoconf version specific libparted checks and
                  defines to feature specific ones
