Update a number of the client-side tools provided with OpenDS to ensure that
they use consistently incrementing message IDs for requests sent to the server.
In at least one case, it was possible for the same message ID to be used by the
client for two consecutive requests, which could trigger a race condition that
caused the server to refuse the second request.

Note that the underlying race condition still exists in the Directory Server
and will need to be addressed through a separate set of changes.
