dojo.rpc.JsonService error handling

[guest]

For server-side errors such as 404 or a badly-formed JSON-RPC response, the dojo.rpc.JsonService? does not call any errback functions.

Instead, it seems the normal callback function is called with a reference to the XmlHttp? object.

Update:

Well-formed error responses that is, responses in the form:

{"error":"foo", "id":5}

also don't invoke the errback. In fact, they call the callback with a reference to the RPC response envelope.

Errback seems to be invoked only when callback throws an error when trying to deal with the RPC envelope.

(In [5785]) make RpcService? and JsonService? errback properly (finally). fixes #1119
