Subject: QPID-1823: Allow recycling of channel IDs

AMQConnection.getNextChannelID: add method to abstract channel id assignment, allow max to be set
AMQConnectionDelegate*: add getMaxChannelID
AMQConnectionDelegate_0_10: use getNextChannelID for this session-id
SessionCreateTest: add test that attempts to create 65555 sessions on one connection
AMQConnectionTest: add unit test for getNextChannelID

SessionCreateTest takes a long, long time to run so is excluded by default

git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@767185 13f79535-47bb-0310-9956-ffa450edef68
