DISPATCH-98: Refactor message annotation handling
Allows the various annotations to be set on a per-message basis.
> Refactor the handling of Message Annotations
> --------------------------------------------
>
> Key: DISPATCH-98
> URL: https://issues.apache.org/jira/browse/DISPATCH-98
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Affects Versions: 0.3
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Minor
> Fix For: 0.5

>
> In order to facility DISPATCH-89, we need to modify the way the router updates the router-specific fields in the Message Annotations section of a forwarded message.
> Currently, all the salient fields - trace, ingress, to-override, etc - are updated all at once prior to forwarding. Let's break this up so fields may be updated individually as needed. Specifically, for DISPATCH-89, the custom forwarding code will need to update the to-override after the route lookup is done. In addition, will need to set unique values for to-override for each copy of the message that is created.
> As an optimization, we should adopt a lazy approach to encoding these field values: only build the final outgoing Message Annotation section as the message is being sent out.
