Metacat

In the call to MNReplication.replicate(), call back to CNReplication.setReplicationStatus() and set the status to failed when we get local exceptions, exceptions from the source MN when calling getReplica(). Send back an exception with a description when setting the status. Add a private setReplicationStatus() method to refactor these calls out.

Modify CNresourceHandler.setReplicationStatus() to use the new API signature, including the failure BaseException that is parsed out of the MMP as a file section. Log the exception message. Since this is an asynchronous call, ReplicationManager won't see a failed status, but the MNAuditTask eventually will.

Add collectReplicationStatus() to CNResourcHandler to return the BaseException or it's subclass, if any, provided in the the call to setReplicationStatus. The exception will be reported on the CN.

Change setReplicationStatus() to drop serialVersion and report the failure exception message in the CN log.

set SystemMetadata.archived=true on MN.delete
There is ongoing discussion on what the exact behavior should be here, but this mimics Metacat's delete-as-archive action.

In MNodeService.replicate(), check to see if we have a replica (via an out of band channel) before we call sourceMN.getReplica().

only create guid->docid mapping during metadata replication if it does not already exist

do not treat access change as an update -- it should not attempt to retrieve the contents of the object
