**=========================================================================
** A method registry maintains a list of functions, and handles

** parameters. All pointers except user_data belong to the library, and
** must not be freed by the callback or used after the callback returns.
**
** env: An XML-RPC error-handling environment. No faults will be
** set when the function is called. If an error occurs,
** set an appropriate fault and return NULL. (If a fault is
** set, the NULL return value will be enforced!)
** host: The 'Host:' header passed by the XML-RPC client, or NULL,
** if no 'Host:' header has been provided.
** method_name: The name used to call this method.
** user_data: The user_data used to register this method.
** param_array: The parameters passed to this function, stored in an
** XML-RPC array. You are *not* responsible for calling
** xmlrpc_DECREF on this array.
**
** Return value: If no fault has been set, the function must return a
** valid xmlrpc_value. This will be serialized, returned
** to the caller, and xmlrpc_DECREF'd.
