Moved banner to the external file to make partial rollout possible. An idea is to have several banners and show them with different probability specified by split directive in the nginx.conf

While building nginx version 0.7.66, 0.8.35 or higher on Linux
the following warning messages are issued:

<programlisting>
warning: `sys_errlist' is deprecated;
    use `strerror' or `strerror_r' instead
warning: `sys_nerr' is deprecated;
    use `strerror' or `strerror_r' instead
</programlisting>

</para>

<para>
<initial>A:</initial>
This is normal: nginx has to use the deprecated sys_errlist[] and sys_nerr
in signal handlers because strerror() and strerror_r() functions
are not Async-Signal-Safe.
