Logical addresses: removing a logical name or UUID/PhysicalAddress mapping on a view change is incorrect
--------------------------------------------------------------------------------------------------------

                 Key: JGRP-918
                 URL: https://jira.jboss.org/jira/browse/JGRP-918
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 2.8


In TP.down(), when receiving a view V, we
- remove all mappings for members not in V from logical_addr_cache and
- remove all mappings in UUID.cache for members not in V

This is incorrect, because

#1  We might have multiple channels in the same JVM, and any given view only pertains to a specific channel C1. But if we remove all mappings for members not in C1's view from UUID.cache, which is a JVM singleton, then we remove mappings for C2's view

#2 With a shared channel, we share TP's logical_addr_cache among all channels, so we cannot do this either
