[Helma-dev] Quick XML-RPC update

[Hannes Wallnoefer]

I updated the XML-RPC library in CVS to Apache XML-RPC 2.0.

This was necessary to handle XML-RPC requests through Helma's ordinary
servlet/req/action pipeline. XML-RPC requests now invoke actions with
suffix _action_xmlrpc, if such a function is defined. The XML-RPC
method name is passed as first argument, XML-RPC parameters are passed
as arguments 1..n. Note that you don't generate a response by writing
to the res object, but by simply returning a XML-RPCable return value
from the action.

Let me know if this works for you, and if you like it, and if I broke
something along the way.
