You're right, I forgot about that.  For no-wait-mode you don't need
multipart.  But it is critical for wait-mode if we are going to send
complete application/ipp responses for each part, since the version,
status, and request-id are positional fields.

But (unless I read it wrong), the current spec allows the printer
to send multiple event notification groups in a single response,
so you can get all your events even without multipart encoding
(for the no wait mode, anyways)
