ACCUMULO-1327 removed commented style info from manual header
ACCUMULO-2583 Change the zookeeper advertisements from port to host:port for replication services.

Centralize all service advertisements for replication (tserver and master) to make
the service discovery a bit easier to manage
ACCUMULO-378 Make MAC set random ports for the replication services.
ACCUMULO-378 Remove unnecessary logging, make proper logging when setSystemProperty ignores an invocation.
ACCUMULO-2574 Add a test class for Status protobufs
ACCUMULO-2572 Make some static helpers to ease programmatic configuration of ReplicaSystems
ACCUMULO-2791 Downgrade commons-codec to match that provided by Hadoop.

* Povide a core.util Base64 class to enforce the non-chunked behavior we rely on
* Changed to use codec 1.4 'shaHex' method
ACCUMULO-2575 Update javadoc and method names on CloseWriteAheadLogReferences to better represent what it does.
ACCUMULO-2575 Update RemoveCompleteReplicationRecords to remove closed, fully replicated entries from both tables.

Because we're lazily passing the state between the metadata and replication tables,
we must scan and submit deletes for each of them separately. There is a race condition
where we might delete an element from metadata only to have the StatusMaker re-make
a record in the replication, but this is acceptable as future invocations of this
class will clean it up for us.
ACCUMULO-378 Better logging inside the ReplicationProcessor
ACCUMULO-378 Remove old files
ACCUMULO-378 WIP to make sure that Work messages with progress update the Status messages
ACCUMULO-378 Finish up the changes to ReplicationTarget and FinishedWorkUpdater.
ACCUMULO-378 Fix the last batch of test and compilation failures.

ACCUMULO-2574 Wrapper around the single-line protobuf toString
ACCUMULO-2581 Change the StatusMaker to delete the entry from metadata when it's closed.

When the Status is closed, we should not see any additional updates that need to
be propagated to the replication table. Thus, we can delete it all at one time instead of
trying to handle the concurrency from trying to do the deletes in another thread.
ACCUMULO-378 Fix some comments and logging.
ACCUMULO-378 More logging, batchwriter mgmt, and test updates.
ACCUMULO-378 Unused imports
