RouterStub: ignore SUSPECT message from GossipRouter if used in TCPGOSSIP
-------------------------------------------------------------------------

                 Key: JGRP-1151
                 URL: https://jira.jboss.org/jira/browse/JGRP-1151
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.8.1, 2.9


When a RouterStub is used in TCPGOSSIP (as opposed to TUNNEL), then the GossipRouter might send unsolicited SUSPECT messages. However, the RouterStub doesn't handle them, as it doesn't have a receiver thread. So when it sends a GET-MEMBERS, and then tries to read the response from the input stream, it might encounter a SUSPECT message first. However, since it doesn't know how to interpret SUSPECT (it tries reading a response), it fails.

SOLUTION: check the input stream before sending a GET-MEMBERS request: if not empty, skip all input available
