Serve WFS in alternate CS: SRSNAME not respected in getfeature, alternate SRS not available

[christinebao]

Reported from Autodesk:

1. In studio, connect to a datalayer in a projected CS, such as state plane or UTM.
2. In studio, define a WFS connection, and be sure to set an EPSG: 4326 CS as the default CS with the native CS as an alternate.
3. Perform a getfeature request using EPSG: 4326 in the string, such as <​http://localhost/mapserver2013/mapagent/mapagent.fcgi?service=wfs&version=1.1.0&request=GetFeature&srsName=epsg:4326&typeName=ns189738229:Untitled1>
4. perform another getfeature, this time with the native CS or no cs in the string, such as <​http://localhost/mapserver2013/mapagent/mapagent.fcgi?service=wfs&version=1.1.0&request=GetFeature&typeName=ns189738229:Untitled1> or <​http://localhost/mapserver2013/mapagent/mapagent.fcgi?service=wfs&version=1.1.0&request=GetFeature&srsName=epsg:25831&typeName=ns189738229:Untitled1>

Expected: native CS values in the results with the native CS request only. The other two should be in LL84 actual: all in native cs
