* implemented the wsdl_set_global_compat_allow_any_header

must be present or an exception is thrown
* fixed a bug handling base type extensions to complexTypes
* improved argument error messages with RPC calls in the
XmlRpcHandler module
* fixed SOAP handler to produce correct URLs in WSDL

gives an empty string
