From 06fc36ba2e32bc5c17ba18c1338f602cb84d54bb Mon Sep 17 00:00:00 2001

Subject: Moved across fixes from trunk for handling exclusive consumers and
 no_local consumption. Fixed close process in AMQChannel (remove channel from
 map only after consumer cancellations have been processed).

git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/branches/qpid.0-9@501144 13f79535-47bb-0310-9956-ffa450edef68
