Subject: erl_docgen: Add anchors to datatypes without name attribute

db_html.xsl generates anchors for data types referred to by strings
(instead of 'name' attributes). For example:

  <datatype>
    <name>edge()</name>
  </datatype>

generates:

  <p><a name="type-edge"><span class="bold_code">edge()</span></a><br></p>
