Two changes in this patch:

1) Management object IDs are now persistent for persistent (durable) objects. This is required to provide continuity of historical management data across broker restarts. The format of object IDs now indicates whether they are transient or persistent. The upper bit (bit 63) is 0 for transient IDs and 1 for persistent IDs.

2) Changes have been made to the management code generator in preparation for allowing it to be used by outside projects that wish to use the broker Plugin API for management access.

File-by-file notes:

M python/mgmt-cli/managementdata.py

    Enhanced user-friendly display of 64-bit object IDs to
    differentiate between persistent IDs and non-persistent IDs.

M cpp/src/Makefile.am

    Changed command line format for call to the management code
    generator.

M cpp/src/qpid/broker/Broker.cpp
M cpp/src/qpid/broker/Vhost.cpp
M cpp/src/qpid/broker/Queue.cpp

    Updated calls to ManagementAgent::addObject to use the new support
    for persistent IDs, ensuring that the management object IDs for
    persistent objects are themselves persistent.

M cpp/src/qpid/management/ManagementAgent.h
M cpp/src/qpid/management/ManagementAgent.cpp

    Added support (using defaulted arguments) to
    ManagementAgent::addObject for persistent object IDs

M cpp/managementgen/generate.py
M cpp/managementgen/schema.py
M cpp/managementgen/main.py

    Added the ability for templates to set variables to be used during
    code generation.

    Makefile fragment is now generated using a template rather than
    hard-code. This was done to help non-qpid code to use the code
    generator for management-via-qpid support.

M cpp/managementgen/templates/Args.h
M cpp/managementgen/templates/Class.cpp
M cpp/managementgen/templates/Class.h

    Use a generator variable to define the comment prefix.

A cpp/managementgen/templates/Makefile.mk

    New template for the qpid makefile fragment.

Queue statistics fixed. Additional objects added (exchange, binding).

Changes:

M cpp/src/qpid/broker/ExchangeRegistry.h
M cpp/src/qpid/broker/ExchangeRegistry.cpp

    ExchangeRegistry was modified to pass a parent pointer to created
    exchanges. This parent reference is not stored but is used to
    link management objects in a hierarchy of ownership.

M cpp/src/qpid/broker/Exchange.h
M cpp/src/qpid/broker/Exchange.cpp

    Exchange now inherits Manageable to make it visible via the
    management interface. The Exchange parent class handles most of
    the management boilerplate. A Binding struct was introduced to
    track bindings for management. This is separate from
    QueueBindings which track bindings for queues.

M cpp/src/qpid/broker/HeadersExchange.h
M cpp/src/qpid/broker/FanOutExchange.h
M cpp/src/qpid/broker/DirectExchange.h
M cpp/src/qpid/broker/TopicExchange.h
M cpp/src/qpid/broker/HeadersExchange.cpp
M cpp/src/qpid/broker/FanOutExchange.cpp
M cpp/src/qpid/broker/DirectExchange.cpp
M cpp/src/qpid/broker/TopicExchange.cpp
M cpp/src/qpid/management/ManagementExchange.cpp
M cpp/src/qpid/management/ManagementExchange.h

    Each exchange type handles management stats in its own specific
    way. Additionally, the constructors pass the management parent
    pointer to the constructor or Exchange.

    An extra layer was added to contain bindings. Instead of directly
    storing bound queues, the exchanges store "bindings" which are
    managable constructs.

M cpp/src/qpid/broker/Broker.cpp

    Broker now explicitly enables the management agent. Also sets the
    management parent (vhost) in the exchange registry.

M cpp/src/qpid/broker/Vhost.cpp

    Updated constructor to be more defensive in case the management
    agent has not been enabled.

M cpp/src/qpid/broker/Queue.cpp

    Same constructor update as vhost. Moved accounting of dequeues
    into "pop". Implemented management method handler (purge).

M cpp/src/qpid/broker/Deliverable.h

    A new method was added to extract the content size of the
    deliverable content (if appropriate). The method is not pure
    virtual and returns zero if not overridden.

M cpp/src/qpid/broker/DeliverableMessage.h
M cpp/src/qpid/broker/TxPublish.cpp
M cpp/src/qpid/broker/DeliverableMessage.cpp
M cpp/src/qpid/broker/TxPublish.h

    These derivatives of Deliverable were updated with overrides for
    contenSize.

M cpp/src/qpid/management/ManagementAgent.h
M cpp/src/qpid/management/ManagementAgent.cpp

    An "enable" method was added to prevent inadvertent creation of a
    management agent when not desired.

    Adding and deleting management objects is now protected by a
    mutex.

    Make sure that deleted objects get reported even if neither their
    configuration nor instrumentation is changed.

M specs/management-schema.xml

    Minor cosmetic updates. Additional parent linkage.

M cpp/managementgen/schema.py
M cpp/managementgen/templates/Class.cpp

    Added generated code to publish schema details for methods.

This patch introduces formal schema specification for management and
code generation for management classes.
