Add support for character maps in serializer

[Gabriel Petrovay]

Zorba serializer does not seem to support character maps.

Why is this marked as invalid?

The query below:

let $sp :=
  <serialization-parameters
      xmlns="http://www.w3.org/2010/xslt-xquery-serialization">
    <use-character-maps>
      <character-map character="#" map-string="123"/>
    </use-character-maps>
  </serialization-parameters>
return
  fn:serialize(<my>#abc</my>, $sp)

issues the result:

&lt;my&gt;#abc&lt;/my&gt;

Shouldn't this be:

&lt;my&gt;123abc&lt;/my&gt;

?

If the bug is still invalid, please clean up the code referencing it in parsing_and_serializing_impl.cpp
