GetRecords hardcoded prefixes in TypeNames check

[heikki]

The check for legal TypeNames in GetRecords, only accepts "csw:Record" or "gmd:MD_Metadata". If an input document uses different prefixes for those namespaces, it's rejected.

This fix checks what the prefixes are for the CSW and the GMD namespace, in the scope of the query element. If not found, default values "csw" and "gmd" are used. The test for legal TypeNames values then uses this prefix for its check.

Computing the namespaces in scope is done using the algorithm in JDOM2 Element, adapted for use with JDOM1.

During testing, this request which was supported is not anymore because it requires the xmlns="​http://www.opengis.net/cat/csw/2.0.2" to be xmlns:csw="http://www.opengis.net/cat/csw/2.0.2" for the typeNames to match

<GetRecords xmlns="http://www.opengis.net/cat/csw/2.0.2" service="CSW" startPosition="1" maxRecords="5" version="2.0.2" resultType="results">
    <Query typeNames="csw:Record">
        <ElementSetName>full</ElementSetName>
        <Constraint version="1.1.0">
            <Filter xmlns="http://www.opengis.net/ogc">
              <PropertyIsEqualTo>
                <PropertyName>subject</PropertyName>
                <Literal>mediterranean-sea</Literal>
              </PropertyIsEqualTo>
            </Filter>
        </Constraint>
    </Query>
</GetRecords>

Also testing that case where no namespace is used in prefix is not supported (but not sure if it needs to be).

<GetRecords xmlns="http://www.opengis.net/cat/csw/2.0.2" service="CSW" startPosition="1" maxRecords="5" version="2.0.2" resultType="results">
    <Query typeNames="Record">
        <ElementSetName>full</ElementSetName>
        <Constraint version="1.1.0">
            <Filter xmlns="http://www.opengis.net/ogc">
              <PropertyIsEqualTo>
                <PropertyName>subject</PropertyName>
                <Literal>mediterranean-sea</Literal>
              </PropertyIsEqualTo>
            </Filter>
        </Constraint>
    </Query>
</GetRecords>
