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

在Linux环境下编译nginx 0.7.66、0.8.35或更高版本时，会出现以下警告：

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

这属于正常情况：nginx必须在信号处理函数中使用过时的sys_errlist[]和sys_nerr，因为strerror()和strerror_r()是非异步信号安全的。
