Remove XFire reference documentation (SPR-7434)

XFire is now CXF (per http://xfire.codehaus.org), and given that Spring
does not actually ship with any explicit XFire support, it makes sense
to remove the documentation completely.  CXF does provide support for
writing services with Spring, and they provide their own documentation.

See http://cxf.apache.org/docs/writing-a-service-with-spring.html

-      <para>XFire is a lightweight SOAP library, hosted by Codehaus. Exposing
-      XFire is done using a XFire context that is shipping with XFire itself in
-      combination with a RemoteExporter-style bean you have to add to your
-      <interfacename>WebApplicationContext</interfacename>. As with all
-      methods that allow you to expose service, you have to create a
-      <classname>DispatcherServlet</classname> with a corresponding
-      <interfacename>WebApplicationContext</interfacename> containing the
-      services you will be exposing:</para>
-
-      <programlisting language="xml">&lt;servlet&gt;
-    &lt;servlet-name&gt;xfire&lt;/servlet-name&gt;
-    &lt;servlet-class&gt;org.springframework.web.servlet.DispatcherServlet&lt;/servlet-class&gt;
-&lt;/servlet&gt;</programlisting>
-
-      <para>You also have to link in the XFire configuration. This is done by
-      adding a context file to the <literal>contextConfigLocations</literal>
-      context parameter picked up by the
-      <classname>ContextLoaderListener</classname> (or
-      <classname>ContextLoaderServlet</classname> for that matter).</para>

-
-      <para>After you added a servlet mapping (mapping <literal>/*</literal>
-      to the XFire servlet declared above) you only have to add one extra bean
-      to expose the service using XFire. Add for example the following
-      configuration in your <filename>'xfire-servlet.xml'</filename>
-      file:</para>
-
-      <programlisting language="xml">&lt;beans&gt;

-    &lt;bean name="/Echo" class="org.codehaus.xfire.spring.remoting.XFireExporter"&gt;
