    Bug Description: large targetattr list with syntax errors cause server to crash or hang
    Reviewed by: nhosoi (Thanks!)
    Branch: 389-ds-base-1.2.9
    Fix Description: If we need to realloc the list to hold more target attributes,
    the list is not NULL terminated.  If there are syntax errors in the aci, the
    function returns with an unterminated list, and this will either cause the
    loop in the free code to go off the end of the list or crash with a segfault.
    The fix is to make sure the list is always NULL terminated.
    Platforms tested: RHEL6 x86_64
