Summary
-------

Patch that removes all the MSG_CALL_SERVER_STARTUP related code that was screwing us more than helping us. Now, when a region server pings back with a different start code, we just shut it down.


This addresses bug HBASE-2613.

> Currently we have a weird piece of code in the master that handles region servers that report but that we don't know about. People likely see:
> {code}
>       LOG.warn("Received report from unknown server -- telling it " +
>         "to " + HMsg.CALL_SERVER_STARTUP + ": " + info.getServerName());
> {code}
> But I never saw that working.correctly, usually the region server will restar-ish and we will likely end up with double assignment.
