Send a label with all messages sent from downstream

Browse Source 
This is preparatory work for forwarding errors of downstream-initiated
messages to their sender, as well as any other unknown message.

Preivously, we only sent labels (for labeled-response) for specific
downstream messages, such as WHO, where we knew the reply should only be
sent to that specific downstream.

However, in the case of an error of a message that is not labeled, the
error reply is not be tagged with a downstream id label and we can't
forward it to a specific downstream. It is not a good solution either to
forward this error to all downstreams.

This adds labels to all downstream-initiated messages (provided the
upstream supports it).
