New Revision: 1058664

URL: http://svn.apache.org/viewvc?rev=1058664&view=rev
Log:
QPID-2982: Fix discrepancy in management object and deleted object counts.

cluster_tests.test_management was showing discrepancy in management
object and deleted object count after a new member update.

In ManagementAgent.cpp, code to move deleted objects into
pendingDeletedObjs was duplicated in 2 places.

Moved duplicated code into a function moveDeletedObjectsLH()

Call moveDeletedObjectsLH from clusterUpdate to correct discrepancy in
object count around update.
