Removed iBatis based components

Browse Source 
This commit removes the iBatis based ItemReaders and ItemWriter.  They
were depricated in the 3.0 line in favor of the MyBatis natively
provided ItemReader and ItemWriter implementations.  This removes those
depricated components.

<title>IbatisPagingItemReader</title>
<note>This reader is deprecated as of Spring Batch 3.0.</note>
<para>If you use IBATIS for your data access then you can use the
<classname>IbatisPagingItemReader</classname> which, as the name
indicates, is an implementation of a paging
<classname>ItemReader</classname>. IBATIS doesn't have direct support
for reading rows in pages but by providing a couple of standard
variables you can add paging support to your IBATIS queries.</para>
<para>Here is an example of a configuration for a
<classname>IbatisPagingItemReader</classname> reading CustomerCredits
as in the examples above:</para>
<programlisting language="xml">&lt;bean id="itemReader" class="org.spr...IbatisPagingItemReader"&gt;
&lt;property name="sqlMapClient" ref="sqlMapClient"/&gt;
&lt;property name="queryId" value="getPagedCustomerCredits"/&gt;
&lt;property name="pageSize" value="1000"/&gt;
&lt;/bean&gt;</programlisting>
<para>The <classname>IbatisPagingItemReader</classname> configuration
above references an IBATIS query called "getPagedCustomerCredits".
Here is an example of what that query should look like for
MySQL.</para>
<programlisting language="xml">&lt;select id="getPagedCustomerCredits" resultMap="customerCreditResult"&gt;
select id, name, credit from customer order by id asc LIMIT #_skiprows#, #_pagesize#
&lt;/select&gt;</programlisting>
<para>The <classname>_skiprows</classname> and
<classname>_pagesize</classname> variables are provided by the
<classname>IbatisPagingItemReader</classname> and there is also a
<classname>_page</classname> variable that can be used if necessary.
The syntax for the paging queries varies with the database used. Here
is an example for Oracle (unfortunately we need to use CDATA for some
operators since this belongs in an XML document):</para>
<programlisting language="xml">&lt;select id="getPagedCustomerCredits" resultMap="customerCreditResult"&gt;
select * from (
select * from (
select t.id, t.name, t.credit, ROWNUM ROWNUM_ from customer t order by id
)) where ROWNUM_ &lt;![CDATA[ &gt; ]]&gt; ( #_page# * #_pagesize# )
) where ROWNUM &lt;![CDATA[ &lt;= ]]&gt; #_pagesize#
&lt;/select&gt;</programlisting>
