Description

Description of problem:
When replication exchange detects duplicated messages, it 1) discards them, and
2) as for any other message, it increases msgIn and byteIn counters. But
msgDrop and byteDrop counters are not updated, though the messages were
discarded.

Version-Release number of selected component (if applicable):
any (incl. 0.14)

How reproducible:
100%

Steps to Reproduce:
1. Setup queue state replication, like
https://cwiki.apache.org/qpid/queue-state-replication.html.
2. Produce 5 messages to the queue-a on the source broker.
3. Restart source broker.
4. Produce another 3 messages to the queue-a on the source broker.

Actual results:
Destination broker (replication exchange in particular) drops the messages
(though these are not duplicates of previously sent - new BZ to be open for
that). Replication exchange increases msgIn and byteIn counters but does not
increase msgDrop and byteDrop counters.

Expected results:
msgDrop and byteDrop counters are also increased.

Additional info:
Patch to be proposed.
