DISPATCH-760: Message annotation handling improvements
This PR replaces existing annotation handling with a more efficient
version. It is fully compatible with 0.8.x.
A comparison with 0.8.x has run on a single laptop. A sender sends a short
message with a varying number of 10-byte user annotations to an ingress router
A. Router A sends the messages to egress router B. A single client is attached
to router B. This comparison is not rigorous and at the
50-annotation-per-message level the producer started to be the limiting factor.
Messages per second. Number of annotations, Nanno, vs router code version,
0.8.x or new.
| Nanno | 0.8.x | new |
|----------|-----------|--------|
| 0 | 26500 | 33700 |
| 1 | 24000 | 33100 |
| 5 | 18000 | 31300 |
| 10 | 14200 | 29700 |
| 20 | 8200 | 25200 |
| 50 | 3500 | 11700 |
