XML-RPC: IXR_Server::output() is notoriously bad at returning the right value for the Content-Length HTTP header. This header is not required, so we will remove it.

"We could of course remove the content-length header as it is not required" was suggested 10 years ago. The IXR library is not maintained. Our release is the latest, which occurred in 2010.

Fixes #2567.
